As of June 17, 2020, all of the Company’s properties, including the subsequently acquired Casino KC and Casino Vicksburg had reopened and are operating in some capacity. The following is an update of re-openings and current operations by property. • Twin River Casino Hotel and Tiverton Casino Hotel - The Rhode Island properties pre-opened on June 8, 2020 with very limited invitation only guests allowed. Beginning June 30, 2020, the Company was able to open to the general public, at approximately 65% capacity, with half of VLTs and a limited number of table games, with a three player limit, available. The hotels at the Rhode Island properties remain closed at this time. • Hard Rock Biloxi - The Biloxi property re-opened to the general public, at 50% capacity, on May 21, 2020 with 41% of VLTs, all table games, with a three player limit, and 75% of the hotel rooms available to guests. Currently, Hard Rock Biloxi is still operating at 50% capacity with over 60% of VLTs and all table games, with a three player limit, available and the hotel is currently operating with all rooms available to guests. • Dover Downs Casino Hotel - The Delaware property re-opened, at 30% capacity, on June 1, 2020, with 45% of VLTs. Table games, with a two player limit, became available to guests on June 17, 2020 and the hotel, at 60% room capacity, became available on June 18, 2020. Currently, the property is operating at approximately 60% capacity, with about half of VLTs, and all table games, with a three player limit, and all hotel rooms available to guests. • Casino KC - Casino KC re-opened, at 50% capacity, on June 1, 2020 with 70% of VLTs and 30% of table games, with a three player limit, available to guests. Casino KC is currently operating with almost 100% of VLTs and a limited number of table games, with a three player limit, available. • Casino Vicksburg - Casino Vicksburg re-opened, at 50% capacity, on May 21, 2020 with 48% of VLTs and 50% of hotel rooms available to guests. Currently, Casino Vicksburg is still operating at 50% capacity, however, over 65% of VLTs are available and the hotel is currently operating with all rooms available to guests. • Black Hawk Casinos - The Black Hawk Casinos re-opened, at 50% capacity, on June 17, 2020 with 55% of VLTs available to guests. Currently, they are still operating at 50% capacity, however, over 64% of VLTs are now available to guests. The Company remains committed to compliance with all state and local operating restrictions as well as and meeting or exceeding all guidelines established by the Centers for Disease Control and Prevention. The Company has implemented property-specific comprehensive health and safety protocols for each of its properties, developed in close consultation with applicable state regulators and public health officials in local jurisdictions. A good percentage of the Company’s operations are expected to continue to be negatively impacted by the COVID-19 pandemic and that impact could be material. Principles of Consolidation The accompanying condensed consolidated financial statements of the Company include the accounts of the Company and its wholly-owned subsidiary TRMG and TRMG’s subsidiaries. All intercompany transactions and balances have been eliminated in the consolidation. Certain prior year amounts have been reclassified to conform to the current year’s presentation. The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial information, including the instructions to Form 10-Q and Rule 10-01 of the SEC’s Regulation S-X. Accordingly, certain information and note disclosures normally required in complete financial statements prepared in conformity with accounting principles generally accepted in the United States have been condensed or omitted. In the Company’s opinion, these condensed consolidated financial statements include all adjustments necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods presented. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. Except as described below and in the Notes to the condensed consolidated financial statements, there were no material changes in significant accounting policies from those described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. We have made estimates and judgments affecting the amounts reported in our condensed consolidated financing statements and the accompanying notes. The inputs into our judgments and estimates consider the economic implications of the COVID-19 pandemic on our critical and significant accounting estimates. The actual results that we experience may differ materially from our estimates. Cash and Cash Equivalents and Restricted Cash The Company considers all cash balances and highly liquid investments with an original maturity of three months or less to be cash and cash equivalents. As of September 30, 2020 and December 31, 2019, restricted cash of $1.9 million and $2.9 million, respectively, was comprised of video lottery terminal (“VLT”) and table games cash, payable to the State of Rhode Island, and certain cash accounts at Dover Downs and Mile High USA, which is unavailable for the Company’s use. The following table reconciles cash and restricted cash in the condensed consolidated balance sheets to the total shown on the condensed consolidated statements of cash flows.

Accounting Policies [Abstract]
RECENTLY ADOPTED AND ISSUED ACCOUNTING PRONOUNCEMENTS	RECENTLY ADOPTED AND ISSUED ACCOUNTING PRONOUNCEMENTS Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments–Credit Losses (Topic 326)–Measurement of Credit Losses on Financial Instruments (“ASC 326”). This standard amends several aspects of the measurement of credit losses on financial instruments, including trade receivables. The standard replaces the existing incurred credit loss model with the Current Expected Credit Losses (“CECL”) model and amends certain aspects of accounting for purchased financial assets with deterioration in credit quality since origination. Under CECL, the allowance for losses for financial assets that are measured at amortized cost reflects management’s estimate of credit losses over the remaining expected life of the financial assets, based on historical experience, current conditions and forecasts that affect the collectability of the reported amount. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments–Credit Losses , to clarify that receivables arising from operating leases are not within the scope of ASC 326 and should instead, be accounted for in accordance with ASC 842, Leases . The standard is effective for annual and interim periods beginning after December 15, 2019. Adoption is through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (a modified-retrospective approach). The Company adopted this ASU in the first quarter of 2020 and recorded a $58,000 negative adjustment to retained earnings as of January 1, 2020. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820),–Disclosure Framework–Changes to the Disclosure Requirements for Fair Value Measurement , which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with the movement amongst or hierarchy associated with Level 1, Level 2 and Level 3 fair value measurements. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company adopted this ASU in the first quarter of 2020, with no impact to its consolidated financial statements. Recently Issued Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-14, Compensation–Retirement Benefits–Defined Benefit Plans–General . This amendment improves disclosures over defined benefit plans and is effective for interim and annual periods ending after December 15, 2020, which for the Company will be the first quarter of 2021, with early adoption permitted. The Company does not expect this amendment to have a significant impact on its consolidated financial statements. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes . This amendment serves to simplify the accounting for income taxes by removing certain exceptions to the general principles in ASC Topic 740, Income Taxes. The amendment also improves the consistent application of ASC Topic 740 by clarifying and amending existing guidance. This amendment is effective for fiscal years, and interim periods within those years, beginning after December 15, 2020, which for the Company will be the first quarter of 2021, with early adoption permitted. The Company is currently in the process of evaluating the impact of this amendment on its consolidated financial statements.

REVENUE RECOGNITION

REVENUE RECOGNITION	9 Months Ended

Revenue from Contract with Customer [Abstract]
REVENUE RECOGNITION	REVENUE RECOGNITION The Company accounts for revenue earned from contracts with customers under ASU No. 2014-09, Revenue from Contracts with Customers (“ASC 606”). The Company generates revenue from five principal sources: gaming services, hotel, racing, food and beverage and other. Gaming revenue includes the share of VLT revenue for Twin River Casino Hotel and Tiverton Casino Hotel, in each case, as determined by each property’s respective master VLT contracts with the State of Rhode Island. Twin River Casino Hotel is entitled to a 28.85% share of VLT revenue on the initial 3,002 units and a 26.00% share of VLT revenue generated from units in excess of 3,002 units. Tiverton Casino Hotel is entitled to receive a percentage of VLT revenue that is equivalent to the percentage received by Twin River Casino Hotel. Gaming revenue also includes Twin River Casino Hotel’s and Tiverton Casino Hotel’s share of table games revenue. Twin River Casino Hotel and Tiverton Casino Hotel each were entitled to an 83.5% share of table games revenue generated as of September 30, 2020. Revenue is recognized when the wager is complete, which is when the customer has received the benefits of the Company’s gaming services and the Company has a present right to payment. The Company records revenue from its Rhode Island operations on a net basis which is the percentage share of VLT and table games revenue received as the Company acts as an agent in operating the gaming services on behalf of the State of Rhode Island. Gaming revenue also includes Dover Downs’ share of revenue as determined under the Delaware State Lottery Code from the date of its acquisition. Dover Downs is authorized to conduct video lottery, sports wagering, table game and internet gaming operations as one of three “Licensed Agents” under the Delaware State Lottery Code. Licensing, administration and control of gaming operations in Delaware is under the Delaware State Lottery Office and Delaware’s Department of Safety and Homeland Security, Division of Gaming Enforcement. As of September 30, 2020 and 2019, Dover Downs was entitled to an approximately 42% share of VLT revenue and an 80% share of table games revenue. Revenue is recognized when the wager is complete, which is when the customer has received the benefits of the Company’s gaming services and the Company has a present right to payment. The Company records revenue from its Delaware operations on a net basis, which is the percentage share of VLT and table games revenue received, as the Company acts as an agent in operating the gaming services on behalf of the State of Delaware. Gaming revenue also includes the casino revenue of Hard Rock Biloxi, the Black Hawk Casinos, and, beginning July 1, 2020, Casino KC and Casino Vicksburg, which is the aggregate net difference between gaming wins and losses, with liabilities recognized for funds deposited by customers before gaming play occurs, for chips outstanding and “ticket-in, ticket-out” coupons in the customers’ possession, and for accruals related to the anticipated payout of progressive jackpots. Progressive slot machines, which contain base jackpots that increase at a progressive rate based on the number of credits played, are charged to revenue as the amount of the progressive jackpots increase. Gaming services contracts have two performance obligations for those customers earning incentives under the Company’s player loyalty programs and a single performance obligation for customers who do not participate in the programs. The Company applies a practical expedient by accounting for its gaming contracts on a portfolio basis as such wagers have similar characteristics and the Company reasonably expects the effects on the condensed consolidated financial statements of applying the revenue recognition guidance to the portfolio to not differ materially from that which would result if applying the guidance to an individual wagering contract. For purposes of allocating the transaction price in a wagering contract between the wagering performance obligation and the obligation associated with incentives earned under loyalty programs, the Company allocates an amount to the loyalty program contract liability based on the stand-alone selling price of the incentive earned for a hotel room stay, food and beverage or other amenity. The performance obligations for the incentives earned under the loyalty programs are deferred and recognized as revenue when the customer redeems the incentive. When redeemed, revenue is recognized in the department that provides the goods or service. After allocating revenue to other goods and services provided as part of casino wager contracts, the Company records the residual amount to gaming revenue as the stand-alone price for wagers is highly variable and no set established price exists for such wagers. The allocated revenue for gaming wagers is recognized when the wagers occur as all such wagers settle immediately. The estimated retail value related to goods and services provided to guests without charge or upon redemption under the Company’s player loyalty programs included in departmental revenues, and therefore reducing gaming revenues, are as follows for the three and nine months ended September 30, 2020 and 2019: Three Months Ended September 30, Nine Months Ended September 30, (in thousands) 2020 2019 2020 2019 Hotel $ 3,962 $ 5,594 $ 9,710 $ 14,528 Food and beverage 4,082 8,940 12,989 22,488 Other 464 1,910 2,270 5,071 $ 8,508 $ 16,444 $ 24,969 $ 42,087 Racing revenue includes Twin River Casino Hotel’s, Tiverton Casino Hotel’s, Mile High USA’s and Dover Downs’ share of wagering from live racing and the import of simulcast signals. Racing revenue is recognized when the wager is complete based on an established take-out percentage. The Company functions as an agent to the pari-mutuel pool. Therefore, fees and obligations related to the Company’s share of purse funding, simulcasting fees, tote fees, pari-mutuel taxes, and other fees directly related to the Company’s racing operations are reported on a net basis and included as a deduction to racing revenue. Hotel revenue is recognized at the time of occupancy, which is when the customer obtains control through occupancy of the room. Advance deposits for hotel rooms are recorded as liabilities until revenue recognition criteria are met. Food and beverage revenue are recognized at the time the goods are sold from Company-operated outlets. All other revenues are recognized at the time the goods are sold or the service is provided. Sales tax and other taxes collected on behalf of governmental authorities are accounted for on a net basis and are not included in revenue or operating expenses. Beginning in the third quarter of 2020, the Company changed its reportable segments to better align with its strategic growth initiatives in light of recent and pending acquisitions.

Revenue included in the operations from the Black Hawk Casinos, from the date of their acquisition, January 23, 2020, through September 30, 2020, and Casino KC from the date of its acquisition, July 1, 2020, through September 30, 2020, is reported in the “West” segment. Revenue included in the operations of Casino Vicksburg, from the date of its acquisition, July 1, 2020, through September 30, 2020, is reported in the “Southeast” segment. Refer to Note 4. “Acquisitions” for further information. The Company’s receivables related to contracts with customers are primarily comprised of marker balances and other amounts due from gaming activities, amounts due for hotel stays, and amounts due from tracks and off track betting (“OTB”) locations. The Company’s receivables related to contracts with customers were $10.6 million and $16.0 million as of September 30, 2020 and December 31, 2019, respectively. The Company has the following liabilities related to contracts with customers: liabilities for loyalty programs, deposits made in advance for goods and services yet to be provided, and unpaid wagers. All of the contract liabilities are short term in nature. Loyalty program incentives earned by customers are typically redeemed within one year from when they are earned and expire if a customer’s account is inactive for more than twelve months; therefore, the majority of these incentives outstanding at the end of a period will either be redeemed or expire within the next twelve months. Certain properties extended pre-COVID-19 tier statuses and/or extended earnings dates for tiered status programs. Additionally, certain properties temporarily suspended periodic purges of unused loyalty points. The Company’s contract liabilities related to loyalty programs were $13.3 million and $12.4 million as of September 30, 2020 and December 31, 2019, respectively, and are included as accrued liabilities in the condensed consolidated balance sheets. The Company recognized $1.4 million and $2.7 million of revenue related to loyalty program redemptions for the three months ended September 30, 2020 and 2019, respectively, and $3.7 million and $7.3 million for the nine months ended September 30, 2020 and 2019, respectively. Advance deposits are typically for future banquet events and to reserve hotel rooms. These deposits are usually received weeks or months in advance of the event or hotel stay. The Company’s contract liabilities related to deposits from customers were $1.0 million and $1.4 million as of September 30, 2020 and December 31, 2019, respectively, and are included as accrued liabilities in the condensed consolidated balance sheets. Unpaid wagers include unpaid pari-mutuel tickets and unpaid sports bet tickets. Unpaid pari-mutuel tickets not claimed within twelve months by the customer who earned them are escheated to the state. The Company’s contract liabilities related to unpaid wagers were $1.0 million and $1.1 million as of September 30, 2020 and December 31, 2019, respectively, and are included as accrued liabilities in the condensed consolidated balance sheets. ASC 606 requires complimentary items to be considered a separate performance obligation, which requires the Company to allocate a portion of revenue from a gaming transaction to other operating revenue based on the estimated standalone selling prices of the promotional items provided. For example, when a casino customer is given a complimentary room, the Company is required to allocate a portion of the casino revenue earned from the customer to hotel revenue based on the estimated standalone selling price of the hotel room. The estimated standalone selling price of hotel rooms is determined based on observable prices. The standalone selling price of food and beverage and other miscellaneous goods and services is determined based upon the actual retail prices charged customers for those items. Revenue is recognized in the period the goods or services are provided.

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS Black Hawk Casinos On January 23, 2020, the Company acquired a subsidiary of Affinity Gaming (“Affinity”) that owns three casino properties located in Black Hawk, Colorado: Golden Gates, Golden Gulch and Mardi Gras (the “Black Hawk Casinos”). The total consideration paid by the Company in connection with the Black Hawk Casinos acquisition was approximately $53.8 million, or $50.5 million net of cash acquired, excluding transaction costs. The Company incurred transaction costs related to this acquisition of $0.2 million and $0.4 million in the three months ended September 30, 2020 and 2019, respectively, and $0.9 million and $1.1 million during the nine months ended September 30, 2020 and 2019, respectively. These costs are included in acquisition, integration and restructuring expenses in the condensed consolidated statements of operations and comprehensive income. The Company accounted for the acquisition of the Black Hawk Casinos as a business combination using the acquisition method with Twin River as the accounting acquirer in accordance with FASB Codification Topic 805, Business Combinations (“ASC 805”) . Under this method of accounting, the purchase price has been allocated to Black Hawk Casinos’ assets acquired and liabilities assumed based upon their estimated fair values at the acquisition date. The identifiable intangible assets recorded in connection with the closing of the Black Hawk acquisition based on preliminary valuations include trademarks of $2.1 million and rated player relationships of $0.6 million, which are being amortized on a straight-line basis over estimated useful lives of approximately 10 years and 6 years, respectively. The Company also initially recorded an intangible asset related to gaming licenses of $3.3 million, with an indefinite life. However, in connection with the impairment testing discussed in Note 5. “Goodwill and Intangible Assets”, the asset was deemed fully impaired and its value was written down to zero as of March 31, 2020. The preliminary fair value of the identifiable intangible assets acquired was determined by using an income approach. Significant assumptions utilized in the income approach were based on company-specific information and projections, which are not observable in the market and are thus considered Level 3 measurements as defined by authoritative guidance. As of September 30, 2020, the purchase price allocation was preliminary and will be finalized when the final assessments of the fair value of all acquired assets and assumed liabilities are completed. There can be no assurance that such finalization will not result in material changes from the preliminary purchase price allocations. The Company’s estimates and assumptions are subject to change during the measurement period (up to one year from the acquisition date). Revenue included in operations from the Black Hawk Casinos, from the date of their acquisition, January 23, 2020, for the three and nine months ended September 30, 2020 was $5.7 million and $11.2 million, respectively. Casino KC and Casino Vicksburg On July 1, 2020, the Company completed its acquisition of the operations and real estate of Casino KC and Casino Vicksburg from affiliates of Eldorado. The total consideration paid by the Company in connection with the acquisition was approximately $229.9 million, or $225.5 million net of cash acquired, excluding transaction costs. The Company recorded transaction costs related to the acquisition of Casino KC and Casino Vicksburg of $0.5 million and $1.4 million during the three and nine months ended September 30, 2020, respectively. These costs are included in acquisition, integration and restructuring expense in the condensed consolidated statements of operations and comprehensive income. The Company accounted for the acquisition of Casino KC and Casino Vicksburg as a business combination using the acquisition method with Twin River as the accounting acquirer in accordance with ASC 805. Under this method of accounting, the purchase price has been allocated to Casino KC’s and Casino Vicksburg’s assets acquired and liabilities assumed based upon their estimated fair values at the acquisition date. The following table summarizes the consideration paid and the preliminary fair values of the assets acquired and liabilities assumed in connection with the acquisition. Due to the fact that the transaction only recently closed, the purchase price allocation is preliminary and will be finalized when valuations are complete and final assessments of the fair value of other acquired assets and assumed liabilities are completed. There can be no assurance that such finalizations will not result in material changes from the preliminary purchase price allocations. The Company’s estimates and assumptions are subject to change during the measurement period (up to one year from the acquisition date), as the Company finalizes the valuations of certain tangible and intangible asset acquired and liabilities assumed.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND INTANGIBLE ASSETS	GOODWILL AND INTANGIBLE ASSETSThe Company performs its annual goodwill impairment test as of the first day of the fourth quarter of each year at the reporting unit level, which is at or one level below the operating segment level. Intangible assets not subject to amortization are reviewed for impairment annually. In addition to the annual impairment test, the Company is required to regularly assess whether a triggering event has occurred which would require interim impairment testing. Late in the first quarter of 2020, as a result of the economic and market conditions surrounding the COVID-19 pandemic and the decline in its stock price and market capitalization the Company experienced at the time, the Company determined that it was more likely than not that the carrying value of all of its reporting units exceeded these units’ fair value and performed an interim quantitative impairment test of goodwill. The Company estimated the fair values of all reporting units using both the market approach, applying a multiple of earnings based on guidelines for publicly traded companies, and the income approach, discounting projected future cash flows based on management’s expectations of the current and future operating environment for each reporting unit. The calculation of the impairment charge includes substantial fact-based determinations and estimates including weighted average cost of capital, future revenue, profitability, cash flows and fair values of assets and liabilities. The rates used to discount projected future cash flows under the income approach reflect a weighted average cost of capital in the range of 10% to 15%, which considered guidelines for publicly traded companies, capital structure and risk premiums, including those reflected in the current market capitalization. The Company corroborated the reasonableness of the estimated reporting unit fair values by reconciling to its enterprise value and market capitalization. Based on this analysis, the Company determined that only the carrying value of its Black Hawk Casinos reporting unit exceeded its fair value by an amount that exceeded the assigned goodwill and indefinite lived intangibles as of the acquisition date. As a result, the Company recorded a total impairment charge of $8.6 million for the nine months ended September 30, 2020, which is included in our “Other” reportable segment, and was allocated between goodwill and intangible assets with charges of $5.3 million and $3.3 million, respectively. The goodwill impairment charge reflects the preliminary goodwill impairment charge of $5.4 million and an adjustment to the charge of $(0.2) million recorded in the first and second quarters of 2020, respectively. The goodwill impairment charge adjustment recorded in the second quarter of 2020 was attributable to changes in the preliminary fair value of net assets, which affected the initial goodwill resulting from the Black Hawk Casinos acquisition. The goodwill impairment charge is reflected in goodwill and asset impairment (adjustment) in the condensed consolidated statements of operations and comprehensive income. The goodwill impairment charge reflects all of the Black Hawk Casinos reporting unit goodwill, based on the preliminary acquisition date assigned fair values. The goodwill impairment charges recorded in the nine months ended September 30, 2020 are subject to change based upon the final purchase price allocation during the measurement period for estimated fair values of assets acquired and liabilities assumed from the Black Hawk Casinos acquisition. There can be no assurance that such final assessments will not result in material increases or decreases to the recorded goodwill and intangible impairment charge based upon the preliminary purchase price allocations, due to changes in the provisional opening balance sheet estimates of goodwill. The Company’s estimates and assumptions are subject to change during the measurement period (up to one year from the acquisition date). Refer to Note 4. “Acquisitions” for further information about the preliminary purchase price allocation and provisional goodwill and intangible balance estimated as of the acquisition date. The change in carrying value of goodwill by reportable segment for the nine months ended September 30, 2020 is as follows: (in thousands) Rhode Island Mid-Atlantic Southeast West Total Goodwill as of December 31, 2019 $ 83,101 $ 1,047 $ 48,934 $ — $ 133,082 Goodwill from current year business acquisitions — — 6,053 52,690 58,743 Impairment charges — — — (5,254) (5,254) Goodwill as of September 30, 2020 $ 83,101 $ 1,047 $ 54,987 $ 47,436 $ 186,571

Leases [Abstract]
LEASES	LEASES Operating Leases The Company is committed under various operating lease agreements primarily related to submerged tidelands, property and equipment. Hard Rock Biloxi has an agreement with the State of Mississippi for the lease and use of approximately five acres of submerged tidelands for a primary term of thirty years, expiring September 30, 2037. Upon expiration of the primary term, Hard Rock Biloxi will have an option to extend the lease for a renewal term of thirty years. The renewal option has not been included in the calculation of the lease liability or right of use asset as the Company is not reasonably certain to exercise the option. Annual rent for the lease, as of September 30, 2020, is approximately $1.2 million and adjusts annually by the increase in the consumer price index (“CPI”). Future changes to the CPI are treated as variable lease payments and are recognized in the period in which the obligation for those payments is incurred. Hard Rock Biloxi also has a Lease and Air Space agreement with the City of Biloxi. The agreement grants the Company rights to a parking area, and to the airspace above two defined parcels of land along with certain support structure rights for the construction of a parking garage. The arrangement has a 40-year term expiring November 18, 2043 and provides the Company one 25-year renewal option. The renewal option has not been included in the calculation of the lease liability or right of use asset as the Company is not reasonably certain to exercise the option. Monthly rent escalates every 5 years based on CPI, and we are responsible for property taxes. Future changes to the CPI are treated as variable lease payments and are recognized in the period in which the obligation for those payments is incurred. In connection with the acquisition of Casino KC, we are party to a sublease with the Port Authority of Kansas City, Missouri, which has leased the property from the City of Kansas City. Our sublease expires on October 18, 2021, but on that date will automatically renew for five additional periods of five years each. The lease agreement provides for minimum annual rent paid in advance and subject to increases in the CPI every five years. Current minimum annual rent payments are $3.1 million per year. In addition, the agreement calls for quarterly percentage rent payments equal to 3.25% of gross revenues, less the minimum annual rent payment. Casino KC is obligated to operate Casino KC at all times. If Casino KC fails to do so, it must pay the Port Authority, in lieu of percentage rent, a sum equal to 50% of the then-applicable base rent during the time Casino KC is not operating. Certain of the Company’s subsidiaries lease office space, parking space, memorabilia and equipment under agreements classified as operating leases that expire on various dates through 2027. Certain of the Company’s leases include renewal options and escalation clauses. Renewal options have not been included in the calculation of the lease liabilities and right of use assets as the Company is not reasonably certain to exercise the options. Discount rates used to determine the present value of the lease payments are based on a credit-adjusted secured borrowing rate commensurate with the term of the lease. Variable expenses generally represent the Company’s share of the landlord’s operating expenses and CPI increases. The Company does not have any leases classified as financing leases. During the nine months ended September 30, 2019, three equipment leases were terminated via purchase of the underlying assets. The Company had operating lease liabilities of approximately $51.4 million and $17.2 million as of September 30, 2020 and December 31, 2019, respectively, and right of use assets of approximately $27.3 million and $17.2 million as of September 30, 2020 and December 31, 2019, respectively, which were included in the condensed consolidated balance sheet.

EQUITY PLANS	EQUITY PLANS The Company has two equity incentive plans: the 2010 BLB Worldwide Holdings, Inc. Stock Option Plan (the “2010 Option Plan”) and the 2015 Stock Incentive Plan (“2015 Incentive Plan”). The 2010 Option Plan provided for options to acquire 2,455,368 shares of the Company’s common stock. Options granted to employees, officers and directors of the Company under the 2010 Option Plan vested on various schedules by individual as defined in the individual participants’ option agreements. Vested options can generally be exercised all or in part at any time until the tenth anniversary of the date of grant. Effective December 9, 2015, it was determined that no new awards would be granted under the 2010 Option Plan. During the three and nine months ended September 30, 2020, there were 19,564 options exercised at a weighted average exercise price of $4.31 per share and an aggregate intrinsic value of $84,000. As of September 30, 2020, there were 90,000 unexercised options outstanding. The 2015 Incentive Plan provides for the grant of stock options, RSAs, RSUs and other stock-based awards (collectively, “restricted awards”) (including those with performance-based vesting criteria) to employees, directors or consultants of the Company. The 2015 Incentive Plan provides for the issuance of up to 1,700,000 shares of the Company’s common stock. During the first quarter of 2020, the Company issued 483,860 RSUs under the 2015 Incentive Plan to eligible employees and executive management as part of its annual equity grant process. These RSUs vest ratably in three annual installments, the first of which vested during the first quarter of 2020.

Retirement Benefits [Abstract]
BENEFIT PLANS	BENEFIT PLANSThe Company participates in and contributes to a number of multiemployer defined benefit pension plans under the terms of collective-bargaining agreements that cover certain of its union-represented employees. The Company acquired a defined benefit pension plan with the acquisition of Dover Downs on March 28, 2019 (“Dover Downs Pension Plan”) which is a non-contributory, tax qualified defined benefit pension plan that has been frozen since July 2011. Dover Downs Defined Benefit Pension Plan As the Company consummated the acquisition of Dover Downs on March 28, 2019, the net periodic benefit (income) cost was immaterial for the three months ended March 31, 2019. The net periodic benefit (income) cost and other changes in plan assets and benefit obligations, excluding service cost, is set forth in the table below for the three and nine months ended September 30, 2020.

Under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), minimum required contributions for single-employer pension plans, including quarterly contributions, that are otherwise due during calendar year 2020 are instead due January 1, 2021. The CARES Act requires that any delayed contributions be increased by interest accrued between the original due date and the date of delayed payment. In July 2020, the Company made a contribution of $0.3 million to the Dover Downs Pension Plan which included the minimum required contributions for both the first and second quarters of 2020, including all applicable interest after having elected not to make a contribution to the Dover Downs Pension Plan for the first quarter of 2020. In September 2020, the Company made a contribution of $0.2 million which represented a final payment for the 2019 plan year. Additionally, in October 2020, the Company made a contribution of $0.2 million to the Dover Downs Pension Plan to include the required contributions, and applicable interest, for the third quarter of 2020. 401(k) Plans The Company has a retirement savings plan under Section 401(k) of the Internal Revenue Code covering non-union employees and certain union employees. The plan allows employees to defer up to the lesser of the Internal Revenue Code prescribed maximum amount or 100% of their income on a pre-tax basis through contributions to the plan. Dover Downs also maintains a defined contribution 401(k) plan, which permits participation by substantially all of its employees. Total employer contribution expense to both 401(k) profit-sharing plans was $0.1 million and $0.6 million for the three and nine months ended September 30, 2020, and $0.4 million and $1.2 million for the three and nine months ended September 30, 2019, respectively.

SHAREHOLDERS’ EQUITY	SHAREHOLDERS’ EQUITY Stock Dividend On January 18, 2019, the Board of Directors of the Company approved a common stock dividend, accounted for as a stock split. The stock split was effected through a stock dividend of three shares for each share outstanding as of the approval date. All share and per share information included in the condensed consolidated financial statements has been retroactively adjusted to reflect the impact of the stock dividend. The shares of common stock authorized remained at 100 million, and the shares retained a par value per share of $0.01. Capital Return Program and Quarterly Cash Dividend On June 14, 2019, the Company announced that its Board of Directors approved a capital return program under which the Company could expend a total of up to $250 million for a share repurchase program and payment of dividends. Share repurchases may be effected in various ways, which could include open-market or private repurchase transactions, accelerated stock repurchase programs, tender offers or other transactions. The amount, timing and terms of any return of capital transaction will be determined based on prevailing market conditions and other factors. The Company expects to fund any share repurchases and dividends from existing capital resources. There is no fixed time period to complete share repurchases. On July 26, 2019, the Company completed a modified Dutch auction tender offer (“Offer”), purchasing 2,504,971 common shares at an aggregate purchase price of $73.9 million. The Offer was funded with cash on hand. On February 10, 2020, the Board of Directors approved an increase in the capital return program of $100 million.

Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTINGAs of September 30, 2020, the Company had eight operating segments, Twin River Casino Hotel, Hard Rock Biloxi, Tiverton Casino Hotel, Dover Downs, the Black Hawk Casinos, Casino KC, Casino Vicksburg and Mile High USA. Beginning in the third quarter of 2020, the Company changed its reportable segments to better align with its strategic growth initiatives in light of recent and pending acquisitions. The growth and diversification achieved through the Company’s acquisitions has resulted in a change in the way the Company's chief operating decision maker makes operating decisions, assesses the performance of the business and allocates resources. As a result, the Company’s operating segments are aggregated into four reportable segments: Rhode Island, Mid-Atlantic, Southeast and West. As of September 30, 2020, the Company’s Rhode Island reportable segment includes Twin River Casino Hotel and Tiverton Casino Hotel, the Mid-Atlantic reportable segment includes only Dover Downs, the Southeast reportable segment includes Hard Rock Biloxi and Casino Vicksburg, the West reportable segment includes Casino KC and the Black Hawk Casinos. The “Other” category includes Mile High USA, an immaterial operating segment, and also includes interest expense for the Company and certain corporate operating expenses that are not allocated to the other segments, which include, among other expenses, share-based compensation, merger and acquisition costs, and certain non-recurring charges. Hard Rock Biloxi and Dover Downs were previously reported as “Biloxi” and “Delaware” reportable segments, respectively, and prior year amounts have been conformed into the new presentation. Black Hawk Casinos was previously included in the “Other’ category since its acquisition on January 23, 2020 The Company is currently evaluating the impact that its pending acquisitions will have on its operating and reporting segments, however the expectation is that Shreveport will be reported with the Southeast, MontBleu with the West and Bally’s with Mid-Atlantic. No determination have been made on Evansville or Jumer’s. The Company’s operations are all within the United States. The Company does not have any revenues from any individual customers that exceed 10% of total reported revenues.

EARNINGS PER SHARE	EARNINGS (LOSS) PER SHARE Basic earnings (loss) per common share (“EPS”) is calculated by dividing net income (loss) per common share by the weighted average number of common shares outstanding and Restricted Stock Units (“RSUs”) and Performance Stock Units (“PSUs”) for which no future service is required as a condition to the delivery of the underlying common stock (collectively, basic shares). Diluted EPS includes the determinants of basic EPS and, in addition, reflects the dilutive effect of the common stock deliverable for stock options, using the treasury stock method, and for RSUs and PSUs for which future service is required as a condition to the delivery of the underlying common stock. The table below presents the computations of basic and diluted EPS: Three Months Ended September 30, Nine Months Ended September 30, (in thousands, except per share data) 2020 2019 2020 2019 Net income (loss) $ 6,723 $ 6,999 $ (25,710) $ 41,775 Weighted average common shares outstanding, basic 30,458 37,809 30,825 39,063 Weighted average effect of dilutive securities 177 116 — 120 Weighted average common shares outstanding, diluted 30,635 37,925 30,825 39,183 Per share data Basic net income (loss) $ 0.22 $ 0.19 $ (0.83) $ 1.07 Diluted net income (loss) $ 0.22 $ 0.18 $ (0.83) $ 1.07

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying condensed consolidated financial statements of the Company include the accounts of the Company and its wholly-owned subsidiary TRMG and TRMG’s subsidiaries. All intercompany transactions and balances have been eliminated in the consolidation. Certain prior year amounts have been reclassified to conform to the current year’s presentation. The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial information, including the instructions to Form 10-Q and Rule 10-01 of the SEC’s Regulation S-X. Accordingly, certain information and note disclosures normally required in complete financial statements prepared in conformity with accounting principles generally accepted in the United States have been condensed or omitted. In the Company’s opinion, these condensed consolidated financial statements include all adjustments necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods presented. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. Except as described below and in the Notes to the condensed consolidated financial statements, there were no material changes in significant accounting policies from those described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents and Restricted Cash The Company considers all cash balances and highly liquid investments with an original maturity of three months or less to be cash and cash equivalents.
Treasury Stock	Treasury StockThe Company records the repurchase of shares of common stock at cost based on the settlement date of the transaction. Upon settlement, these shares are classified as treasury stock, which is a reduction to shareholders’ equity. Treasury stock is included in authorized and issued shares but excluded from outstanding shares
Recently Adopted and Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments–Credit Losses (Topic 326)–Measurement of Credit Losses on Financial Instruments (“ASC 326”). This standard amends several aspects of the measurement of credit losses on financial instruments, including trade receivables. The standard replaces the existing incurred credit loss model with the Current Expected Credit Losses (“CECL”) model and amends certain aspects of accounting for purchased financial assets with deterioration in credit quality since origination. Under CECL, the allowance for losses for financial assets that are measured at amortized cost reflects management’s estimate of credit losses over the remaining expected life of the financial assets, based on historical experience, current conditions and forecasts that affect the collectability of the reported amount. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments–Credit Losses , to clarify that receivables arising from operating leases are not within the scope of ASC 326 and should instead, be accounted for in accordance with ASC 842, Leases . The standard is effective for annual and interim periods beginning after December 15, 2019. Adoption is through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (a modified-retrospective approach). The Company adopted this ASU in the first quarter of 2020 and recorded a $58,000 negative adjustment to retained earnings as of January 1, 2020. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820),–Disclosure Framework–Changes to the Disclosure Requirements for Fair Value Measurement , which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with the movement amongst or hierarchy associated with Level 1, Level 2 and Level 3 fair value measurements. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company adopted this ASU in the first quarter of 2020, with no impact to its consolidated financial statements. Recently Issued Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-14, Compensation–Retirement Benefits–Defined Benefit Plans–General . This amendment improves disclosures over defined benefit plans and is effective for interim and annual periods ending after December 15, 2020, which for the Company will be the first quarter of 2021, with early adoption permitted. The Company does not expect this amendment to have a significant impact on its consolidated financial statements. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes . This amendment serves to simplify the accounting for income taxes by removing certain exceptions to the general principles in ASC Topic 740, Income Taxes. The amendment also improves the consistent application of ASC Topic 740 by clarifying and amending existing guidance. This amendment is effective for fiscal years, and interim periods within those years, beginning after December 15, 2020, which for the Company will be the first quarter of 2021, with early adoption permitted. The Company is currently in the process of evaluating the impact of this amendment on its consolidated financial statements.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets, Policy	The Company performs its annual goodwill impairment test as of the first day of the fourth quarter of each year at the reporting unit level, which is at or one level below the operating segment level. Intangible assets not subject to amortization are reviewed for impairment annually. In addition to the annual impairment test, the Company is required to regularly assess whether a triggering event has occurred which would require interim impairment testing. Late in the first quarter of 2020, as a result of the economic and market conditions surrounding the COVID-19 pandemic and the decline in its stock price and market capitalization the Company experienced at the time, the Company determined that it was more likely than not that the carrying value of all of its reporting units exceeded these units’ fair value and performed an interim quantitative impairment test of goodwill.

Due to the fact that the transaction only recently closed, the purchase price allocation is preliminary and will be finalized when valuations are complete and final assessments of the fair value of other acquired assets and assumed liabilities are completed. There can be no assurance that such finalizations will not result in material changes from the preliminary purchase price allocations. The Company’s estimates and assumptions are subject to change during the measurement period (up to one year from the acquisition date), as the Company finalizes the valuations of certain tangible and intangible asset acquired and liabilities assumed.

Schedule of Recognized Identified Assets Acquired and Liabilities Assumed			The following table summarizes the consideration paid and the preliminary fair values of the assets acquired and liabilities assumed in connection with the acquisition. Due to the fact that the transaction only recently closed, the purchase price allocation is preliminary and will be finalized when valuations are complete and final assessments of the fair value of other acquired assets and assumed liabilities are completed. There can be no assurance that such finalizations will not result in material changes from the preliminary purchase price allocations. The Company’s estimates and assumptions are subject to change during the measurement period (up to one year from the acquisition date), as the Company finalizes the valuations of certain tangible and intangible asset acquired and liabilities assumed.
