Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	Basis of Presentation and Organization. Pinnacle Entertainment, Inc. is an owner, operator and developer of casinos and related hospitality and entertainment facilities. References in these footnotes to “Pinnacle,” the “Company,” “we,” “our” or “us” refer to Pinnacle Entertainment, Inc. and its subsidiaries, except where stated or the context otherwise indicates.
	We own and operate 15 gaming entertainment properties, located in Colorado, Indiana, Iowa, Louisiana, Mississippi, Missouri, Nevada, and Ohio. We also hold a majority interest in the racing license owner, and we are a party to a management contract, for Retama Park Racetrack located outside of San Antonio, Texas. In addition to these properties, we own and operate a live and televised poker tournament series under the trade name Heartland Poker Tour. We view each of our operating properties as an operating segment with the exception of our two properties in Jackpot, Nevada, which we view as one operating segment. For financial reporting purposes, we aggregate our operating segments into the following reportable segments:
	Midwest segment, which includes:	Location
	Ameristar Council Bluffs	Council Bluffs, Iowa
	Ameristar East Chicago	East Chicago, Indiana
	Ameristar Kansas City	Kansas City, Missouri
	Ameristar St. Charles	St. Charles, Missouri
	River City	St. Louis, Missouri
	Belterra	Florence, Indiana
	Belterra Park	Cincinnati, Ohio
	South segment, which includes:	Location
	Ameristar Vicksburg	Vicksburg, Mississippi
	Boomtown Bossier City	Bossier City, Louisiana
	Boomtown New Orleans	New Orleans, Louisiana
	L'Auberge Baton Rouge	Baton Rouge, Louisiana
	L'Auberge Lake Charles	Lake Charles, Louisiana
	West segment, which includes:	Location
	Ameristar Black Hawk	Black Hawk, Colorado
	Cactus Petes and Horseshu	Jackpot, Nevada
	The operating results of Lumière Place Casino, HoteLumière, the Four Seasons Hotel St. Louis, and related excess land parcels (collectively, the “Lumière Place Casino and Hotels”) have been classified as discontinued operations in our unaudited Condensed Consolidated Statements of Operations. In April 2014, we completed the sale of the ownership interests in the Lumière Place Casino and Hotels. For further information, see Note 7, “Discontinued Operations and Assets Held for Sale.” Our unaudited Condensed Consolidated Statements of Cash Flows have not been adjusted for discontinued operations.
	In November 2014, we announced that our Board of Directors approved a plan to pursue a separation of our operating assets and real estate assets into two publicly traded companies, in which we have proposed separating our real estate assets through the creation of a newly formed, publicly traded, real estate investment trust (“REIT”), the common stock of which would be distributed to our stockholders in a tax-free spin-off (“REIT transaction”), with Pinnacle remaining an operating entity following the transaction. In May 2015, we announced that we have engaged in productive discussions with Gaming and Leisure Properties, Inc. (“GLPI”), a publicly traded real estate investment trust, regarding their potential acquisition of our real estate assets. If a definitive agreement were entered into with respect to the potential acquisition by GLPI of our real estate assets, such a transaction would be in lieu of effecting our own REIT transaction. There can be no assurance that we will enter into a definitive agreement with GLPI related to a potential transaction or that a transaction will be consummated.
	Principles of Consolidation. The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with the instructions of the Securities and Exchange Commission (the “SEC”) to the Quarterly Report on Form 10-Q and, therefore, do not include all information and notes necessary for complete financial statements in conformity with generally accepted accounting principles in the United States (“GAAP”). The results for the periods indicated are unaudited, but reflect all adjustments, which are of a normal recurring nature, that management considers necessary for a fair presentation of operating results. The unaudited Condensed Consolidated Financial Statements include the accounts of Pinnacle Entertainment, Inc. and its subsidiaries. Investments in the common stock of unconsolidated affiliates in which we have the ability to exercise significant influence are accounted for under the equity method. All intercompany accounts and transactions have been eliminated in consolidation.
	The results of operations for interim periods are not indicative of a full year of operations. These unaudited Condensed Consolidated Financial Statements and notes thereto should be read in conjunction with the Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K filed with the SEC for the fiscal year ended December 31, 2014.
	Use of Estimates. The preparation of unaudited Condensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect (i) the reported amounts of assets and liabilities, (ii) the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and (iii) the reported amounts of revenues and expenses during the reporting period. Estimates used by us include, among other things, the estimated useful lives for depreciable and amortizable assets, the estimated allowance for doubtful accounts receivable, estimated income tax provisions, the evaluation of the future realization of deferred tax assets, determining the adequacy of reserves for self-insured liabilities and our customer loyalty programs, estimated cash flows in assessing the recoverability of long-lived assets, asset impairments, goodwill and intangible assets, contingencies and litigation, and estimates of the forfeiture rate and expected life of share-based awards and stock price volatility when computing share-based compensation expense. Actual results may differ from those estimates.
	Fair Value. Fair value measurements affect our accounting and impairment assessments of our long-lived assets, investments in unconsolidated affiliates, assets acquired in an acquisition, goodwill, and other intangible assets. Fair value measurements also affect our accounting for certain financial assets and liabilities. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and is measured according to a hierarchy that includes: “Level 1” inputs, such as quoted prices in an active market for identical assets or liabilities; “Level 2” inputs, which are observable inputs for similar assets; or “Level 3” inputs, which are unobservable inputs.
	The following table presents a summary of fair value measurements by level for certain liabilities measured at fair value on a recurring basis in the unaudited Condensed Consolidated Balance Sheets:
					Fair Value Measurements Using:
		Total Fair Value			Level 1			Level 2		Level 3
		(in millions)
	As of March 31, 2015
	Liabilities:
	Deferred compensation	$	0.4		$	0.4		$	—	$	—
	As of December 31, 2014
	Liabilities:
	Deferred compensation	$	0.6		$	0.6		$	—	$	—
	The following table presents a summary of fair value measurements by level for certain financial instruments not measured at fair value on a recurring basis in the unaudited Condensed Consolidated Balance Sheets for which it is practicable to estimate fair value:
								Fair Value Measurements Using:
		Total Carrying Value			Total Fair Value			Level 1		Level 2		Level 3
	As of March 31, 2015	(in millions)
	Assets:
	Held-to-maturity securities	$	14.6		$	21.1		$	—	$	17.9	$	3.2
	Promissory notes	$	12.8		$	17.4		$	—	$	17.4	$	—
	Liabilities:
	Long-term debt	$	3,883.50		$	4,026.20		$	—	$	4,026.20	$	—
	As of December 31, 2014
	Assets:
	Held-to-maturity securities	$	14.8		$	21.7		$	—	$	18.5	$	3.2
	Promissory notes	$	12		$	16.8		$	—	$	16.8	$	—
	Liabilities:
	Long-term debt	$	3,986.60		$	4,029.90		$	—	$	4,029.90	$	—
	The estimated fair values for certain of our long-term held-to-maturity securities and our long-term promissory notes were based on Level 2 inputs using observable market data for comparable instruments in establishing prices.
	The estimated fair values for certain of our long-term held-to-maturity securities were based on Level 3 inputs using a present value of future cash flow valuation technique that relies on management assumptions and qualitative observations. Key significant unobservable inputs in this technique include discount rate risk premiums and probability-weighted cash flow scenarios.
	The estimated fair values of our long-term debt, which includes the fair value of our senior notes, senior subordinated notes, senior secured credit facility and term loans, were based on Level 2 inputs of observable market data on comparable debt instruments on or about March 31, 2015, and December 31, 2014.
	The fair values of our short term financial instruments approximate the carrying values due to their short term nature.
	Land, Buildings, Vessels and Equipment. Land, buildings, vessels and equipment are stated at cost. Land includes land not currently being used in our operations, which totaled $35.0 million at March 31, 2015. We capitalize the costs of improvements that extend the life of the asset. We expense repair and maintenance costs as incurred. Gains or losses on the disposition of land, buildings, vessels and equipment are included in the determination of income.
	We review the carrying value of our land, buildings, vessels and equipment used in our operations whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable from estimated future undiscounted cash flows expected to result from its use and eventual disposition. If the undiscounted cash flows exceed the carrying value, no impairment is indicated. If the undiscounted cash flows do not exceed the carrying value, then an impairment charge is recorded based on the fair value of the asset.
	Development costs directly associated with the acquisition, development, and construction of a project are capitalized as a cost of the project, during the periods in which activities necessary to get the property ready for its intended use are in progress. The costs incurred for development projects are carried at cost. Interest costs associated with development projects are capitalized as part of the cost of the constructed asset. When no debt is incurred specifically for a project, interest is capitalized on amounts expended for the project using our weighted-average cost of borrowing. Capitalization of interest ceases when the project, or discernible portion of the project, is substantially complete. If substantially all of the construction activities of a project are suspended, capitalization of interest will cease until such activities are resumed. For further discussion, see Note 2, “Long-Term Debt.”
	The following table presents a summary of our land, buildings, vessels and equipment:
		March 31,			December 31,
		2015			2014
		(in millions)
	Land, buildings, vessels and equipment:
	Land and land improvements	$	400.6		$	401.9

Less: accumulated depreciation	(917.9		)	(860.2		)
Land, buildings, vessels and equipment, net	$	2,964.30		$	3,017.00
Equity Method Investments. We apply equity method accounting for investments when we do not control the investee, but have the ability to exercise significant influence over its operating and finance policies. Equity method investments are recorded at cost, with the allocable portion of the investee's income or loss reported in earnings, and adjusted for capital contributions to and distributions from the investee. Distributions in excess of equity method earnings, if any, are recognized as a return of investment and recorded as investing cash flows in the unaudited Condensed Consolidated Statements of Cash Flows. We review our equity method investments for impairment whenever events or changes in circumstances indicate that the carrying value of our investment may have experienced an other-than-temporary decline in value.
Goodwill and Other Intangible Assets. Goodwill and other indefinite-lived intangible assets are subject to an annual assessment for impairment during the fourth quarter, or more frequently if there are indications of possible impairment, by applying a qualitative and/or quantitative fair-value-based test. There were no impairments to goodwill or intangible assets recognized during the three months ended March 31, 2015, or 2014. In April 2015, we made our final installment payment of $25.0 million for Belterra Park's VLT license, which we had accrued as of March 31, 2015, and December 31, 2014, in “Other accrued liabilities” in our unaudited Condensed Consolidated Balance Sheets.
Customer Loyalty Programs. We offer incentives to our customers through our mychoice customer loyalty program. Under the mychoice customer loyalty program, customers earn points based on their level of play that may be redeemed for various benefits, such as cash back, dining, or hotel stays, among others. The reward credit balance under the plan will be forfeited if the customer does not earn any reward credits over the prior six-month period. In addition, based on their level of play, customers can earn additional benefits without redeeming points, such as a car lease, among other items.
We accrue a liability for the estimated cost of providing these benefits as the benefits are earned. Estimates and assumptions are made regarding cost of providing the benefits, breakage rates, and the mix of goods and services customers will choose. We use historical data to assist in the determination of estimated accruals. Changes in estimates or customer redemption habits could produce significantly different results. As of March 31, 2015, and December 31, 2014, we had accrued $27.7 million and $26.6 million, respectively, for the estimated cost of providing mychoice benefits. Such amounts are included in “Other accrued liabilities” in our unaudited Condensed Consolidated Balance Sheets.
Revenue Recognition. Gaming revenues consist of the net win from gaming activities, which is the difference between amounts wagered and amounts paid to winning patrons. Cash discounts and other cash incentives to customers related to gaming play are recorded as a reduction to gaming revenue. Food and beverage, lodging, retail, entertainment, and other operating revenues are recognized as products are delivered or services are performed. Advanced deposits on lodging are recorded as accrued liabilities until services are provided to the customer.
The retail value of food and beverage, lodging and other services furnished to guests on a complimentary basis is included in revenues and then deducted as promotional allowances in calculating total revenues. The estimated cost of providing such promotional allowances is primarily included in gaming expenses. Complimentary revenues that have been excluded from the accompanying unaudited Condensed Consolidated Statements of Operations were as follows:
	For the three months ended March 31,
	2015			2014
	(in millions)
Food and beverage	$	35.2		$	33.2
Lodging	15.2			16
Other	4.4			3.7
Total promotional allowances	$	54.8		$	52.9
The costs to provide such complimentary benefits were as follows:
	For the three months ended March 31,
	2015			2014
	(in millions)
Promotional allowance costs included in gaming expense	$	39.3		$	38.1
Gaming Taxes. We are subject to taxes based on gross gaming revenues in the jurisdictions in which we operate, subject to applicable jurisdictional adjustments. These gaming taxes are an assessment on our gaming revenues and are recorded as a gaming expense in the unaudited Condensed Consolidated Statements of Operations. These taxes were as follows:
	For the three months ended March 31,
	2015			2014
	(in millions)
Gaming taxes	$	144.7		$	132.8
Pre-opening, Development and Other Costs. Pre-opening, development and other costs consist of payroll costs to hire, employ and train the workforce prior to opening an operating facility; marketing campaigns prior to and in connection with the opening; legal and professional fees related to the project but not otherwise attributable to depreciable assets; lease payments; real estate taxes; acquisition costs; restructuring costs; and other costs prior to the opening of an operating facility. Pre-opening, development and other costs are expensed as incurred. Pre-opening, development and other costs consist of the following:
	For the three months ended March 31,
	2015			2014
	(in millions)
Ameristar acquisition (1)	$	0.4		$	0.5
Belterra Park (2)	—			2.7
Other (3)	1.2			0.2
Total pre-opening, development and other costs	$	1.6		$	3.4
-1	Amounts principally comprised of legal and advisory expenses, severance charges and other costs and expenses related to the financing and integration of the acquisition of Ameristar Casinos, Inc. ("Ameristar").
-2	Belterra Park opened on May 1, 2014.
-3	For the three months ended March 31, 2015, total includes $0.7 million of cost associated with our pursuit of a REIT spin-off transaction.
Earnings per Share. The computation of basic and diluted earnings per share (“EPS”) is based on net income attributable to Pinnacle Entertainment, Inc. divided by the basic weighted average number of common shares and diluted weighted average number of common shares, respectively. Diluted earnings per share reflect the addition of potentially dilutive securities, which include in-the-money stock options and restricted stocks units. A total of 1.4 million and 1.3 million out-of-money stock options were excluded from the calculation of diluted earnings per share for the three months ended March 31, 2015, and 2014, respectively, because including them would have been anti-dilutive.
Reclassifications. The unaudited Condensed Consolidated Financial Statements reflect certain reclassifications to prior year amounts to conform to classification in the current period. These reclassifications had no effect on the previously reported net income amounts.
Recently Issued Accounting Pronouncements
In April 2014, the FASB issued an accounting standards update in connection with reporting discontinued operations and disclosures of disposals of components of entities. The accounting standards update changes the criteria for reporting discontinued operations. Under the amendment, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results when any of the following occurs: (i) the component of an entity or group of components of an entity meets the criteria to be classified as held for sale; (ii) the component of an entity or group of components of an entity is disposed of by sale; and (iii) the component of an entity or group of components of an entity is disposed of other than by sale. This new guidance is effective prospectively for all disposals (or classifications as held for sale) of components of an entity and all business activities, on acquisition, that are classified as held for sale that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. We adopted this guidance during the first quarter of 2015 and it did not have a material impact on our unaudited Condensed Consolidated Financial Statements.
In May 2014, as part of its ongoing efforts to assist in the convergence of GAAP and International Financial Reporting Standards, the FASB issued a new standard related to revenue recognition. Under the new standard, recognition of revenue occurs when a customer obtains control of promised services or goods in an amount that reflects the consideration to which the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts. The new standard will be effective for fiscal years beginning after December 15, 2016. We are currently evaluating the impact of adopting this accounting standard on our unaudited Condensed Consolidated Financial Statements.
In June 2014, the FASB issued an accounting standards update with respect to performance share awards. This accounting standards update requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period or periods for which the requisite service has already been rendered. The effective date for this update is for the annual and interim periods beginning after December 15, 2015. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on our unaudited Condensed Consolidated Financial Statements.
In April 2015, the FASB issued an accounting standards update which changes the presentation of debt issuance costs in financial statements. Under the new standard, an entity presents such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. The amortization of the costs is reported as interest expense. The new guidance should be applied on a retrospective basis, wherein the balance sheet of each individual period should be adjusted to reflect the period-specific effects of applying the new guidance. The effective date for this update is for the annual and interim periods beginning after December 15, 2015. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on our unaudited Condensed Consolidated Financial Statements.
A variety of proposed or otherwise potential accounting standards are currently under review and study by standard-setting organizations and certain regulatory agencies. Given the tentative and preliminary nature of such proposed standards, we have not yet determined the effect, if any, that the implementation of any such proposed or revised standards would have on our unaudited Condensed Consolidated Financial Statements.

	Senior Secured Credit Facility: In August 2013, we entered into an Amended and Restated Credit Agreement (“Credit Facility”), which amended and restated our Fourth Amended and Restated Credit Agreement dated as of August 2, 2011, as amended. The Credit Facility consists of (i) $1.6 billion of term loans comprised of $500.0 million of Tranche B-1 term loans and $1.1 billion of Tranche B-2 term loans and (ii) a $1.0 billion revolving credit commitment. As of March 31, 2015, we had approximately $561.6 million drawn under the $1.0 billion revolving credit facility, approximately $724.5 million outstanding principal Tranche B-2 term loan debt, and approximately $13.2 million committed under various letters of credit under our Credit Facility. We fully repaid the outstanding principal balances of our Tranche B-1 term loans during 2014. The outstanding principal on the Tranche B-2 term loans has been discounted on issuance for the reduction in the proceeds received when the transaction was consummated.
	6.375% Senior Notes due 2021: In August 2013, we issued $850.0 million in aggregate principal amount of 6.375% senior notes due 2021 (“6.375% Notes”) to fund the acquisition of Ameristar. The 6.375% Notes bear interest at a rate of 6.375% per year, payable semi-annually in arrears on February 1st and August 1st of each year. The 6.375% Notes mature on August 1, 2021. Net of initial purchasers’ fees and various costs and expenses, proceeds from the offering were approximately $835.0 million.
	7.50% Senior Notes due 2021: As part of the acquisition of Ameristar, we assumed $1.04 billion in aggregate principal amount of 7.50% Senior Notes due 2021 (“7.50% Notes”) that were originally issued by Ameristar. The 7.50% Notes bear interest at a rate of 7.50% per year, payable semi-annually in arrears on April 15th and October 15th of each year. The 7.50% Notes mature on April 15, 2021. The 7.50% Notes were recorded at fair value as part of the purchase price allocation with a premium of $72.8 million. In addition, a consent fee payment to the holders of the 7.50% Notes at acquisition was included as a discount component of the total carrying value.
	7.75% Senior Subordinated Notes due 2022: In March 2012, we issued $325.0 million in aggregate principal amount of 7.75% senior subordinated notes due 2022 (“7.75% Notes”). The 7.75% Notes were issued at par with interest payable on April 1st and October 1st of each year. The 7.75% Notes mature on April 1, 2022. Net of initial purchasers’ fees and various costs and expenses, proceeds from the offering were approximately $318.3 million.
	8.75% Senior Subordinated Notes due 2020: In May 2010, we issued $350.0 million in aggregate principal amount of 8.75% senior subordinated notes due 2020 (“8.75% Notes”). The 8.75% Notes were issued at par with interest payable on May 15th and November 15th of each year. The 8.75% Notes mature on May 15, 2020. Net of the initial purchasers' fees and various costs and expenses, proceeds from the offering were approximately $341.5 million.
	Interest expense, net, was as follows:

	Our effective income tax rate for continuing operations for the three months ended March 31, 2015, was 15.1%, or an expense of $4.8 million, as compared to an effective tax rate of 10.5%, or an expense of $2.2 million, for the corresponding prior-year period. Our tax rate differs from the statutory rate of 35.0% due to the effects of permanent items, deferred tax expense on tax amortization of indefinite-lived intangible assets, state taxes, and a reserve for unrecognized tax benefits. Our state tax provision represents taxes in the jurisdictions of Indiana and Louisiana as well as the city jurisdictions in Missouri, where we have no valuation allowance.

	Equity Method Investment: As of March 31, 2015, we have invested $2.0 million in Farmworks, a land re-vitalization project in downtown St. Louis, which is accounted for under the equity method and included in “Other assets, net” in our unaudited Condensed Consolidated Balance Sheets. For the three months ended March 31, 2015, our proportional share of Farmworks' losses totaled $0.1 million. The carrying value of this investment was $1.7 million and $1.8 million as of March 31, 2015, and December 31, 2014, respectively.
	Retama Park Racetrack: We hold 75.5% of the equity of Pinnacle Retama Partners, LLC (“PRP”) and consolidate the accounts of PRP in our Condensed Consolidated Financial Statements. As of March 31, 2015, PRP held $12.8 million in promissory notes issued by Retama Development Corporation (“RDC”), a local government corporation of the City of Selma, Texas, included in “Other assets, net” in our unaudited Condensed Consolidated Balance Sheets. The promissory notes have long-term contractual maturities and are collateralized by Retama Park Racetrack assets. The contractual terms of these promissory notes include interest payments due at maturity. We have not recorded accrued interest on these promissory notes because uncertainty exists as to RDC's ability to make interest payments.
	As of March 31, 2015, we held, at amortized cost, $11.4 million in local government corporation bonds, with long-term contractual maturities, issued by RDC, a local government corporation of the City of Selma, Texas, included in “Other assets, net” in our unaudited Condensed Consolidated Balance Sheets. We have both the intent and ability to hold these investments until the amortized cost is recovered.

	Discontinued operations and assets classified as held for sale are measured at the lower of their carrying values or the fair value less cost to sell. The fair value of the assets to be sold was determined using a market approach using Level 2 inputs, as defined in Note 1, “Summary of Significant Accounting Policies.”
	Lumiére Place Casino and Hotels: In August 2013, we entered into an Equity Interest Purchase Agreement to sell the ownership interests in certain of our subsidiaries, which own and operate the Lumiére Place Casino and Hotels. During 2014, we completed the sale of the ownership interests in these subsidiaries for net cash consideration of $250.3 million.
	Boomtown Reno: As of March 31, 2015, we held 783 acres of land surrounding our former Boomtown Reno operations, with a carrying value of approximately $8.3 million. In April 2015, we completed the sale of this land for cash consideration of approximately $13.2 million.
	Springfield, Massachusetts: As of March 31, 2015, we owned approximately 40 acres of land in Springfield, Massachusetts, originally purchased by Ameristar for a possible future casino resort, with a carrying value of approximately $3.5 million. In April 2015, we completed the sale of this land for cash consideration of approximately $12.0 million.

Insurance reserves include accruals for estimated settlements for known claims, as well as accruals for estimates of claims not yet made. As of March 31, 2015, and December 31, 2014, we had total self-insurance accruals of $24.2 million and $24.4 million, respectively, which are included in “Other accrued liabilities” in our unaudited Condensed Consolidated Balance Sheets.
	Indiana Tax Dispute: In 2008, the Indiana Department of Revenue (the “IDR”) commenced an examination of our Indiana income tax filings for the years 2005, 2006, and 2007. In 2010, we received a proposed assessment in the amount of $7.3 million, excluding interest and penalties. We filed a protest requesting abatement of all taxes, interest and penalties and had two hearings with the IDR where we provided additional facts and support. At issue is whether income and gains from certain asset sales, including the sale of the Hollywood Park Racetrack in 1999, and other transactions outside of Indiana, such as the Aztar merger termination fee in 2006, which we reported on our Indiana state tax returns for the years 2000 through 2007, resulted in business income subject to apportionment. In April 2012, we received a supplemental letter of findings from the IDR that denied our protest on most counts. In the supplemental letter of findings, the IDR did not raise any new technical arguments or advance any new theory that would alter our judgment regarding the recognition or measurement of the unrecognized tax benefit related to this audit. We believe that our tax return position is sustainable on the merits. In June 2012, we filed a tax appeal petition with the Indiana tax court to set aside the final assessment. In August 2013, we filed a Motion for Partial Summary Judgment on the 1999 Hollywood Park sale. We asked the court to grant summary judgment in our favor based on the technical merit of Indiana tax law. In January 2014, oral arguments were held at the Indiana Tax Court regarding our motion for summary judgment. As of March 31, 2015, the Company is still awaiting the issuance of the Indiana Tax Court's ruling on our Motion for Partial Summary Judgment.
	Other: We are a party to a number of other pending legal proceedings. Management does not expect that the outcome of such proceedings, either individually or in the aggregate, will have a material effect on our financial position, cash flows or results of operations.

	(a)	See Note 1, “Summary of Significant Accounting Policies,” for listing of properties included in each segment.
	(b)	We define Consolidated Adjusted EBITDA as earnings before interest income and expense, income taxes, depreciation, amortization, pre-opening, development and other costs, non-cash share-based compensation, asset impairment costs, write-downs, reserves, recoveries, corporate-level litigation settlement costs, gain (loss) on sale of certain assets, loss on early extinguishment of debt, gain (loss) on sale of equity security investments, income (loss) from equity method investments, non-controlling interest and discontinued operations. We define Adjusted EBITDA for each operating segment as earnings before interest income and expense, income taxes, depreciation, amortization, pre-opening, development and other costs, non-cash share-based compensation, asset impairment costs, write-downs, reserves, recoveries, inter-company management fees, gain (loss) on sale of certain assets, gain (loss) on early extinguishment of debt, gain (loss) on sale of discontinued operations, and discontinued operations. We define Adjusted EBITDA margin as Adjusted EBITDA for the segment divided by segment revenues. We use Consolidated Adjusted EBITDA and Adjusted EBITDA for each segment to compare operating results among our properties and between accounting periods. Consolidated Adjusted EBITDA and Adjusted EBITDA have economic substance because they are used by management as measures to analyze the performance of our business and are especially relevant in evaluating large, long-lived casino-hotel projects because they provide a perspective on the current effects of operating decisions separated from the substantial non-operational depreciation charges and financing costs of such projects. We eliminate the results from discontinued operations at the time they are deemed discontinued. We also review pre-opening, development and other costs separately, as such expenses are also included in total project costs when assessing budgets and project returns, and because such costs relate to anticipated future revenues and income. We believe that Consolidated Adjusted EBITDA and Adjusted EBITDA are useful measures for investors because they are indicators of the performance of ongoing business operations. These calculations are commonly used as a basis for investors, analysts and credit rating agencies to evaluate and compare operating performance and value of companies within our industry. In addition, our credit agreement and bond indentures require compliance with financial measures similar to Consolidated Adjusted EBITDA. Consolidated Adjusted EBITDA should not be considered as an alternative to operating income as an indicator of performance, or as an alternative to any other measure provided in accordance with GAAP. Our calculations of Adjusted EBITDA and Consolidated Adjusted EBITDA may be different from the calculation methods used by other companies and, therefore, comparability may be limited.
	(c)	Corporate and other includes revenues from Retama Park Racetrack (which we manage) and the Heartland Poker Tour. Corporate expenses represent payroll, professional fees, travel expenses and other general and administrative expenses not directly related to our casino and hotel operations. Beginning in the 2013 third quarter, we changed the methodology used to allocate corporate expenses to our reportable segments. Historically, we allocated direct and some indirect expenses incurred at the corporate headquarters to each property. Expenses incurred at the corporate headquarters that were related to property operations, but not directly attributable to a specific property, were allocated, typically on a pro rata basis, to each property. Only the remaining corporate expenses that were not related to an operating property were retained in the Corporate expense category. Under our new methodology, only corporate expenses that are directly attributable to a property were allocated to each applicable property. All other costs incurred relating to management and consulting services provided by corporate headquarters to the properties are now allocated to those properties based on their respective share of the monthly consolidated net revenues in the form of a management fee. The corporate management fee is excluded in the calculation of segment Adjusted EBITDA and is completely eliminated in any consolidated financial results. The change in methodology increases Adjusted EBITDA for the reportable segments with a corresponding increase in corporate expense, resulting in no impact to Consolidated Adjusted EBITDA.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Organization	Basis of Presentation and Organization. Pinnacle Entertainment, Inc. is an owner, operator and developer of casinos and related hospitality and entertainment facilities. References in these footnotes to “Pinnacle,” the “Company,” “we,” “our” or “us” refer to Pinnacle Entertainment, Inc. and its subsidiaries, except where stated or the context otherwise indicates.
	We own and operate 15 gaming entertainment properties, located in Colorado, Indiana, Iowa, Louisiana, Mississippi, Missouri, Nevada, and Ohio. We also hold a majority interest in the racing license owner, and we are a party to a management contract, for Retama Park Racetrack located outside of San Antonio, Texas. In addition to these properties, we own and operate a live and televised poker tournament series under the trade name Heartland Poker Tour. We view each of our operating properties as an operating segment with the exception of our two properties in Jackpot, Nevada, which we view as one operating segment. For financial reporting purposes, we aggregate our operating segments into the following reportable segments:
	Midwest segment, which includes:	Location
	Ameristar Council Bluffs	Council Bluffs, Iowa
	Ameristar East Chicago	East Chicago, Indiana
	Ameristar Kansas City	Kansas City, Missouri
	Ameristar St. Charles	St. Charles, Missouri
	River City	St. Louis, Missouri
	Belterra	Florence, Indiana
	Belterra Park	Cincinnati, Ohio
	South segment, which includes:	Location
	Ameristar Vicksburg	Vicksburg, Mississippi
	Boomtown Bossier City	Bossier City, Louisiana
	Boomtown New Orleans	New Orleans, Louisiana
	L'Auberge Baton Rouge	Baton Rouge, Louisiana
	L'Auberge Lake Charles	Lake Charles, Louisiana
	West segment, which includes:	Location
	Ameristar Black Hawk	Black Hawk, Colorado
	Cactus Petes and Horseshu	Jackpot, Nevada
	The operating results of Lumière Place Casino, HoteLumière, the Four Seasons Hotel St. Louis, and related excess land parcels (collectively, the “Lumière Place Casino and Hotels”) have been classified as discontinued operations in our unaudited Condensed Consolidated Statements of Operations. In April 2014, we completed the sale of the ownership interests in the Lumière Place Casino and Hotels. For further information, see Note 7, “Discontinued Operations and Assets Held for Sale.” Our unaudited Condensed Consolidated Statements of Cash Flows have not been adjusted for discontinued operations.
	In November 2014, we announced that our Board of Directors approved a plan to pursue a separation of our operating assets and real estate assets into two publicly traded companies, in which we have proposed separating our real estate assets through the creation of a newly formed, publicly traded, real estate investment trust (“REIT”), the common stock of which would be distributed to our stockholders in a tax-free spin-off (“REIT transaction”), with Pinnacle remaining an operating entity following the transaction. In May 2015, we announced that we have engaged in productive discussions with Gaming and Leisure Properties, Inc. (“GLPI”), a publicly traded real estate investment trust, regarding their potential acquisition of our real estate assets. If a definitive agreement were entered into with respect to the potential acquisition by GLPI of our real estate assets, such a transaction would be in lieu of effecting our own REIT transaction. There can be no assurance that we will enter into a definitive agreement with GLPI related to a potential transaction or that a transaction will be consummated.
Principles of Consolidation	Principles of Consolidation. The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with the instructions of the Securities and Exchange Commission (the “SEC”) to the Quarterly Report on Form 10-Q and, therefore, do not include all information and notes necessary for complete financial statements in conformity with generally accepted accounting principles in the United States (“GAAP”). The results for the periods indicated are unaudited, but reflect all adjustments, which are of a normal recurring nature, that management considers necessary for a fair presentation of operating results. The unaudited Condensed Consolidated Financial Statements include the accounts of Pinnacle Entertainment, Inc. and its subsidiaries. Investments in the common stock of unconsolidated affiliates in which we have the ability to exercise significant influence are accounted for under the equity method. All intercompany accounts and transactions have been eliminated in consolidation.
	The results of operations for interim periods are not indicative of a full year of operations. These unaudited Condensed Consolidated Financial Statements and notes thereto should be read in conjunction with the Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K filed with the SEC for the fiscal year ended December 31, 2014.
Use of Estimates	Use of Estimates. The preparation of unaudited Condensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect (i) the reported amounts of assets and liabilities, (ii) the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and (iii) the reported amounts of revenues and expenses during the reporting period. Estimates used by us include, among other things, the estimated useful lives for depreciable and amortizable assets, the estimated allowance for doubtful accounts receivable, estimated income tax provisions, the evaluation of the future realization of deferred tax assets, determining the adequacy of reserves for self-insured liabilities and our customer loyalty programs, estimated cash flows in assessing the recoverability of long-lived assets, asset impairments, goodwill and intangible assets, contingencies and litigation, and estimates of the forfeiture rate and expected life of share-based awards and stock price volatility when computing share-based compensation expense. Actual results may differ from those estimates.
Fair Value	Fair Value. Fair value measurements affect our accounting and impairment assessments of our long-lived assets, investments in unconsolidated affiliates, assets acquired in an acquisition, goodwill, and other intangible assets. Fair value measurements also affect our accounting for certain financial assets and liabilities. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and is measured according to a hierarchy that includes: “Level 1” inputs, such as quoted prices in an active market for identical assets or liabilities; “Level 2” inputs, which are observable inputs for similar assets; or “Level 3” inputs, which are unobservable inputs.
Land, Buildings, Vessels and Equipment	Land, Buildings, Vessels and Equipment. Land, buildings, vessels and equipment are stated at cost. Land includes land not currently being used in our operations, which totaled $35.0 million at March 31, 2015. We capitalize the costs of improvements that extend the life of the asset. We expense repair and maintenance costs as incurred. Gains or losses on the disposition of land, buildings, vessels and equipment are included in the determination of income.
	We review the carrying value of our land, buildings, vessels and equipment used in our operations whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable from estimated future undiscounted cash flows expected to result from its use and eventual disposition. If the undiscounted cash flows exceed the carrying value, no impairment is indicated. If the undiscounted cash flows do not exceed the carrying value, then an impairment charge is recorded based on the fair value of the asset.
	Development costs directly associated with the acquisition, development, and construction of a project are capitalized as a cost of the project, during the periods in which activities necessary to get the property ready for its intended use are in progress. The costs incurred for development projects are carried at cost. Interest costs associated with development projects are capitalized as part of the cost of the constructed asset. When no debt is incurred specifically for a project, interest is capitalized on amounts expended for the project using our weighted-average cost of borrowing. Capitalization of interest ceases when the project, or discernible portion of the project, is substantially complete. If substantially all of the construction activities of a project are suspended, capitalization of interest will cease until such activities are resumed. For further discussion, see Note 2, “Long-Term Debt.”
Equity Method Investments	Equity Method Investments. We apply equity method accounting for investments when we do not control the investee, but have the ability to exercise significant influence over its operating and finance policies. Equity method investments are recorded at cost, with the allocable portion of the investee's income or loss reported in earnings, and adjusted for capital contributions to and distributions from the investee. Distributions in excess of equity method earnings, if any, are recognized as a return of investment and recorded as investing cash flows in the unaudited Condensed Consolidated Statements of Cash Flows. We review our equity method investments for impairment whenever events or changes in circumstances indicate that the carrying value of our investment may have experienced an other-than-temporary decline in value.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets. Goodwill and other indefinite-lived intangible assets are subject to an annual assessment for impairment during the fourth quarter, or more frequently if there are indications of possible impairment, by applying a qualitative and/or quantitative fair-value-based test.
Customer Loyalty Programs	Customer Loyalty Programs. We offer incentives to our customers through our mychoice customer loyalty program. Under the mychoice customer loyalty program, customers earn points based on their level of play that may be redeemed for various benefits, such as cash back, dining, or hotel stays, among others. The reward credit balance under the plan will be forfeited if the customer does not earn any reward credits over the prior six-month period. In addition, based on their level of play, customers can earn additional benefits without redeeming points, such as a car lease, among other items.
	We accrue a liability for the estimated cost of providing these benefits as the benefits are earned. Estimates and assumptions are made regarding cost of providing the benefits, breakage rates, and the mix of goods and services customers will choose. We use historical data to assist in the determination of estimated accruals. Changes in estimates or customer redemption habits could produce significantly different results.
Revenue Recognition	Revenue Recognition. Gaming revenues consist of the net win from gaming activities, which is the difference between amounts wagered and amounts paid to winning patrons. Cash discounts and other cash incentives to customers related to gaming play are recorded as a reduction to gaming revenue. Food and beverage, lodging, retail, entertainment, and other operating revenues are recognized as products are delivered or services are performed. Advanced deposits on lodging are recorded as accrued liabilities until services are provided to the customer.
	The retail value of food and beverage, lodging and other services furnished to guests on a complimentary basis is included in revenues and then deducted as promotional allowances in calculating total revenues. The estimated cost of providing such promotional allowances is primarily included in gaming expenses.
Gaming Taxes	Gaming Taxes. We are subject to taxes based on gross gaming revenues in the jurisdictions in which we operate, subject to applicable jurisdictional adjustments.
Earnings Per Share	Earnings per Share. The computation of basic and diluted earnings per share (“EPS”) is based on net income attributable to Pinnacle Entertainment, Inc. divided by the basic weighted average number of common shares and diluted weighted average number of common shares, respectively. Diluted earnings per share reflect the addition of potentially dilutive securities, which include in-the-money stock options and restricted stocks units.
Reclassifications	Reclassifications. The unaudited Condensed Consolidated Financial Statements reflect certain reclassifications to prior year amounts to conform to classification in the current period. These reclassifications had no effect on the previously reported net income amounts.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements
	In April 2014, the FASB issued an accounting standards update in connection with reporting discontinued operations and disclosures of disposals of components of entities. The accounting standards update changes the criteria for reporting discontinued operations. Under the amendment, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results when any of the following occurs: (i) the component of an entity or group of components of an entity meets the criteria to be classified as held for sale; (ii) the component of an entity or group of components of an entity is disposed of by sale; and (iii) the component of an entity or group of components of an entity is disposed of other than by sale. This new guidance is effective prospectively for all disposals (or classifications as held for sale) of components of an entity and all business activities, on acquisition, that are classified as held for sale that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. We adopted this guidance during the first quarter of 2015 and it did not have a material impact on our unaudited Condensed Consolidated Financial Statements.
	In May 2014, as part of its ongoing efforts to assist in the convergence of GAAP and International Financial Reporting Standards, the FASB issued a new standard related to revenue recognition. Under the new standard, recognition of revenue occurs when a customer obtains control of promised services or goods in an amount that reflects the consideration to which the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts. The new standard will be effective for fiscal years beginning after December 15, 2016. We are currently evaluating the impact of adopting this accounting standard on our unaudited Condensed Consolidated Financial Statements.
	In June 2014, the FASB issued an accounting standards update with respect to performance share awards. This accounting standards update requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period or periods for which the requisite service has already been rendered. The effective date for this update is for the annual and interim periods beginning after December 15, 2015. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on our unaudited Condensed Consolidated Financial Statements.
	In April 2015, the FASB issued an accounting standards update which changes the presentation of debt issuance costs in financial statements. Under the new standard, an entity presents such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. The amortization of the costs is reported as interest expense. The new guidance should be applied on a retrospective basis, wherein the balance sheet of each individual period should be adjusted to reflect the period-specific effects of applying the new guidance. The effective date for this update is for the annual and interim periods beginning after December 15, 2015. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on our unaudited Condensed Consolidated Financial Statements.
	A variety of proposed or otherwise potential accounting standards are currently under review and study by standard-setting organizations and certain regulatory agencies. Given the tentative and preliminary nature of such proposed standards, we have not yet determined the effect, if any, that the implementation of any such proposed or revised standards would have on our unaudited Condensed Consolidated Financial Statements.

	(b)	We define Consolidated Adjusted EBITDA as earnings before interest income and expense, income taxes, depreciation, amortization, pre-opening, development and other costs, non-cash share-based compensation, asset impairment costs, write-downs, reserves, recoveries, corporate-level litigation settlement costs, gain (loss) on sale of certain assets, loss on early extinguishment of debt, gain (loss) on sale of equity security investments, income (loss) from equity method investments, non-controlling interest and discontinued operations. We define Adjusted EBITDA for each operating segment as earnings before interest income and expense, income taxes, depreciation, amortization, pre-opening, development and other costs, non-cash share-based compensation, asset impairment costs, write-downs, reserves, recoveries, inter-company management fees, gain (loss) on sale of certain assets, gain (loss) on early extinguishment of debt, gain (loss) on sale of discontinued operations, and discontinued operations. We define Adjusted EBITDA margin as Adjusted EBITDA for the segment divided by segment revenues. We use Consolidated Adjusted EBITDA and Adjusted EBITDA for each segment to compare operating results among our properties and between accounting periods. Consolidated Adjusted EBITDA and Adjusted EBITDA have economic substance because they are used by management as measures to analyze the performance of our business and are especially relevant in evaluating large, long-lived casino-hotel projects because they provide a perspective on the current effects of operating decisions separated from the substantial non-operational depreciation charges and financing costs of such projects. We eliminate the results from discontinued operations at the time they are deemed discontinued. We also review pre-opening, development and other costs separately, as such expenses are also included in total project costs when assessing budgets and project returns, and because such costs relate to anticipated future revenues and income. We believe that Consolidated Adjusted EBITDA and Adjusted EBITDA are useful measures for investors because they are indicators of the performance of ongoing business operations. These calculations are commonly used as a basis for investors, analysts and credit rating agencies to evaluate and compare operating performance and value of companies within our industry. In addition, our credit agreement and bond indentures require compliance with financial measures similar to Consolidated Adjusted EBITDA. Consolidated Adjusted EBITDA should not be considered as an alternative to operating income as an indicator of performance, or as an alternative to any other measure provided in accordance with GAAP. Our calculations of Adjusted EBITDA and Consolidated Adjusted EBITDA may be different from the calculation methods used by other companies and, therefore, comparability may be limited.
	(c)	Corporate and other includes revenues from Retama Park Racetrack (which we manage) and the Heartland Poker Tour. Corporate expenses represent payroll, professional fees, travel expenses and other general and administrative expenses not directly related to our casino and hotel operations. Beginning in the 2013 third quarter, we changed the methodology used to allocate corporate expenses to our reportable segments. Historically, we allocated direct and some indirect expenses incurred at the corporate headquarters to each property. Expenses incurred at the corporate headquarters that were related to property operations, but not directly attributable to a specific property, were allocated, typically on a pro rata basis, to each property. Only the remaining corporate expenses that were not related to an operating property were retained in the Corporate expense category. Under our new methodology, only corporate expenses that are directly attributable to a property were allocated to each applicable property. All other costs incurred relating to management and consulting services provided by corporate headquarters to the properties are now allocated to those properties based on their respective share of the monthly consolidated net revenues in the form of a management fee. The corporate management fee is excluded in the calculation of segment Adjusted EBITDA and is completely eliminated in any consolidated financial results. The change in methodology increases Adjusted EBITDA for the reportable segments with a corresponding increase in corporate expense, resulting in no impact to Consolidated Adjusted EBITDA.

[1]	We define Consolidated Adjusted EBITDA as earnings before interest income and expense, income taxes, depreciation, amortization, pre-opening, development and other costs, non-cash share-based compensation, asset impairment costs, write-downs, reserves, recoveries, corporate-level litigation settlement costs, gain (loss) on sale of certain assets, loss on early extinguishment of debt, gain (loss) on sale of equity security investments, income (loss) from equity method investments, non-controlling interest and discontinued operations. We define Adjusted EBITDA for each operating segment as earnings before interest income and expense, income taxes, depreciation, amortization, pre-opening, development and other costs, non-cash share-based compensation, asset impairment costs, write-downs, reserves, recoveries, inter-company management fees, gain (loss) on sale of certain assets, gain (loss) on early extinguishment of debt, gain (loss) on sale of discontinued operations, and discontinued operations. We define Adjusted EBITDA margin as Adjusted EBITDA for the segment divided by segment revenues. We use Consolidated Adjusted EBITDA and Adjusted EBITDA for each segment to compare operating results among our properties and between accounting periods. Consolidated Adjusted EBITDA and Adjusted EBITDA have economic substance because they are used by management as measures to analyze the performance of our business and are especially relevant in evaluating large, long-lived casino-hotel projects because they provide a perspective on the current effects of operating decisions separated from the substantial non-operational depreciation charges and financing costs of such projects. We eliminate the results from discontinued operations at the time they are deemed discontinued. We also review pre-opening, development and other costs separately, as such expenses are also included in total project costs when assessing budgets and project returns, and because such costs relate to anticipated future revenues and income. We believe that Consolidated Adjusted EBITDA and Adjusted EBITDA are useful measures for investors because they are indicators of the performance of ongoing business operations. These calculations are commonly used as a basis for investors, analysts and credit rating agencies to evaluate and compare operating performance and value of companies within our industry. In addition, our credit agreement and bond indentures require compliance with financial measures similar to Consolidated Adjusted EBITDA. Consolidated Adjusted EBITDA should not be considered as an alternative to operating income as an indicator of performance, or as an alternative to any other measure provided in accordance with GAAP. Our calculations of Adjusted EBITDA and Consolidated Adjusted EBITDA may be different from the calculation methods used by other companies and, therefore, comparability may be limited.
[2]	See Note 1, “Summary of Significant Accounting Policies,” for listing of properties included in each segment.
[3]	Corporate and other includes revenues from Retama Park Racetrack (which we manage) and the Heartland Poker Tour. Corporate expenses represent payroll, professional fees, travel expenses and other general and administrative expenses not directly related to our casino and hotel operations. Beginning in the 2013 third quarter, we changed the methodology used to allocate corporate expenses to our reportable segments. Historically, we allocated direct and some indirect expenses incurred at the corporate headquarters to each property. Expenses incurred at the corporate headquarters that were related to property operations, but not directly attributable to a specific property, were allocated, typically on a pro rata basis, to each property. Only the remaining corporate expenses that were not related to an operating property were retained in the Corporate expense category. Under our new methodology, only corporate expenses that are directly attributable to a property were allocated to each applicable property. All other costs incurred relating to management and consulting services provided by corporate headquarters to the properties are now allocated to those properties based on their respective share of the monthly consolidated net revenues in the form of a management fee. The corporate management fee is excluded in the calculation of segment Adjusted EBITDA and is completely eliminated in any consolidated financial results. The change in methodology increases Adjusted EBITDA for the reportable segments with a corresponding increase in corporate expense, resulting in no impact to Consolidated Adjusted EBITDA.
