Organization Consolidation And Presentation Of Financial Statements [Abstract]
Overview and Summary of Significant Accounting Policies	1. Overview and Summary of Significant Accounting Policies Organization and Description of Business Zynga Inc. (“Zynga,” “we” or “the Company”) develops, markets, and operates social games as live services played over the Internet and on social networking sites and mobile platforms. We generate revenue through the in-game sale of virtual goods and through advertising. Our operations are headquartered in San Francisco, California, and we have several operating locations in the U.S., as well as various international office locations in North America, Asia and Europe. We completed our initial public offering in December 2011 and our Class A common stock is listed on the NASDAQ Global Select Market under the symbol “ZNGA.” Basis of Presentation and Consolidation The accompanying consolidated financial statements are presented in accordance with United States generally accepted accounting principles (“U.S. GAAP”). The consolidated financial statements include the operations of us and our wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in the consolidation. The accompanying interim consolidated financial statements and these related notes should be read in conjunction with the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2015. Unaudited Interim Financial Information The accompanying interim consolidated balance sheet as of March 31, 2016, the interim consolidated statements of operations, the interim consolidated statements of comprehensive income (loss) for the three months ended March 31, 2016 and 2015, the interim consolidated statements of cash flows for the three months ended March 31, 2016 and 2015 and the related footnote disclosures are unaudited. These unaudited consolidated interim financial statements have been prepared in accordance with U.S. GAAP. In management’s opinion, the unaudited consolidated interim financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments of a normal recurring nature necessary for the fair presentation of the Company’s statement of financial position and operating results for the periods presented. The results for the three months ended March 31, 2016 are not necessarily indicative of the results expected for the full fiscal year or any other future period. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and notes thereto. Significant estimates and assumptions reflected in the financial statements include, but are not limited to, the estimated lives of virtual goods that we use for revenue recognition, useful lives of property and equipment and intangible assets, accrued liabilities, income taxes, accounting for business combinations, stock-based expense and evaluation of goodwill, intangible assets, and long-lived assets for impairment. Actual results could differ materially from those estimates. Changes in our estimated average life of durable virtual goods during the three months ended March 31, 2016 for various games resulted in an increase in revenue and income from operations of $2.6 million, which is the result of adjusting the remaining recognition period of deferred revenue generated in prior periods at the time of a change in estimate. We also recognized $1.3 million of revenue and income from continuing operations in the three months ended March 31, 2016 due to changes in our estimated average life of durable virtual goods for games that have been discontinued as there is no further service obligation after the closure of these games. These changes in estimates resulted in a $0.01 per share impact on our reported earnings per share for the three months ended March 31, 2016.

The estimated fair value of available-for-sale marketable securities, classified by their contractual maturities was as follows (in thousands): March 31, 2016 Due within one year $ 126,010 After one year through three years — Total $ 126,010 Changes in market interest rates and bond yields caused certain investments to fall below their cost basis, resulting in unrealized losses on marketable securities. As of March 31, 2016, we had unrealized losses of $5 thousand related to marketable securities that had a fair value of $29.8 million. As of December 31, 2015, we had unrealized losses of $0.1 million related to marketable securities that had a fair value of $199.1 million. None of these securities were in a material continuous unrealized loss position for more than 12 months. As of March 31, 2016 and December 31, 2015, we did not consider any of our marketable securities to be other-than-temporarily impaired. When evaluating our investments for other-than-temporary impairment, we review factors such as the length of time and extent to which fair value has been below its cost basis, the financial condition of the issuer, our ability and intent to hold the security to maturity and whether it is more likely than not that we will be required to sell the investment before recovery of its cost basis.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	3. Fair Value Measurements Our financial instruments consist of cash equivalents, short-term marketable securities and accounts receivable. Accounts receivable, net is stated at its carrying value, which approximates fair value. Cash equivalents and short-term marketable securities, consisting of money market funds, U.S. government and government agency debt securities and corporate debt securities, are carried at fair value, which is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between knowledgeable and willing market participants. Our contingent consideration liability represents the estimated fair value of the additional consideration payable in connection with our acquisitions of Rising Tide Games, Inc. (“Rising Tide Games”) and Zindagi Games, Inc. (“Zindagi Games”). The amount payable is contingent upon the achievement of certain performance milestones. We estimated the acquisition date fair value of the contingent consideration payable using discounted cash flow models, and applied a discount rate that appropriately captured a market participant’s view of the risk associated with the obligations. The significant unobservable inputs used in the fair value measurement of the acquisition-related contingent consideration payable were forecasted future cash flows and the timing of those cash flows and the risk-adjusted discount rate. Significant changes in actual and forecasted future cash flows may result in significant charges or benefits to our future operating expenses. In the third quarter of 2015, we acquired Rising Tide Games. Under the terms of the agreement, the contingent consideration may be payable based on the achievement of certain future performance targets during the three year period following the acquisition date. We initially estimated the acquisition date fair value of the contingent consideration payable using discounted cash flow models, and applied a risk-adjusted discount rate that appropriately captured a market participant’s view of the risk associated with the obligations. In the first quarter of 2016, we updated this analysis and recorded the change in estimated fair value of the contingent consideration liability as an expense of approximately $2.0 million within Research and Development in our consolidated statement of operations. The current contingent consideration liability is $20.5 million; however, the maximum contingent consideration that could be earned and payable by us is $140.0 million. In the first quarter of 2016, we acquired Zindagi Games. Under the terms of the agreement, the contingent consideration may be payable based on the achievement of certain future performance targets during the three year period following the acquisition date. The current contingent consideration liability is $1.3 million, however, the maximum contingent consideration that could be earned and payable by us is $60.0 million. Fair value is a market-based measurement that should be determined based on assumptions that knowledgeable and willing market participants would use in pricing an asset or liability. The valuation techniques used to measure the fair value of the Company’s debt instruments and all other financial instruments, all of which have counterparties with high credit ratings, were valued based on quoted market prices or model-driven valuations using significant inputs derived from or corroborated by observable market data. We use a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 — Includes inputs, other than Level 1 inputs, that are directly or indirectly observable in the marketplace. Level 3 — Unobservable inputs that are supported by little or no market activity. The composition of our financial assets and liabilities among the three Levels of the fair value hierarchy are as follows (in thousands): March 31, 2016 Level 1 Level 2 Level 3 Total Assets: Money market funds (1) $ 533,675 $ — $ — $ 533,675 U.S. government and government agency debt securities — 68,014 — 68,014 Corporate debt securities (1) — 124,956 — 124,956 Total $ 533,675 $ 192,970 $ — $ 726,645 Liabilities: Contingent consideration $ — $ — $ 21,780 $ 21,780 December 31, 2015 Level 1 Level 2 Level 3 Total Assets: Money market funds (1) $ 362,587 $ — $ — $ 362,587 U.S. government and government agency debt securities — 184,975 — 184,975 Corporate debt securities (1) — 277,193 — 277,193 Total $ 362,587 $ 462,168 $ — $ 824,755 Liabilities: Contingent consideration $ — $ — $ 18,490 $ 18,490 (1) Includes amounts classified as cash and cash equivalents.

Accordingly, these assets were written down to their fair value and reclassified from property and equipment to other current assets, with $83.9 million and $80.7 million being reclassified from computer equipment and accumulated depreciation respectively, for a net amount of $3.2 million. The $3.2 million reflects the fair value of the assets less estimated costs to sell. During the first quarter of 2016, $0.4 million of the assets meeting held for sale criteria were sold.

Acquisitions On January 1, 2016, we acquired Zindagi Games, a provider of social games, for purchase consideration of approximately $13.8 million, which consisted of cash paid of $12.5 million (net of prepaid compensation expense of $2.5 million) and contingent consideration with a fair value of $1.3 million. The contingent consideration may be payable based on the achievement of certain future performance targets during the three year period following the acquisition date and could be up to $60.0 million. We will record changes in the fair value of contingent consideration liabilities within operating expenses in our consolidated statement of operations each future reporting period. For further details on our fair value methodology with respect to contingent consideration liabilities, see Note 3 – “Fair Value Measurements”.

Income Taxes	7. Income Taxes The expense from income taxes increased by $0.9 million in the three months ended March 31, 2016 as compared to the same period of the prior year. This increase was primarily attributable to an increase in foreign tax expense of $0.9 million related to a change in our jurisdictional mix of earnings and uncertain tax positions. Once the Company is profitable, we expect our global effective tax rate to be less than the U.S. statutory income tax rate.

Earnings Per Share [Abstract]
Net Income (Loss) Per Share of Common Stock	11. Net Income (Loss) Per Share of Common Stock Basic net income (loss) per share is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. In computing diluted net income (loss) attributable to common stockholders, net income (loss) is re-allocated to reflect the potential impact of dilutive securities, including stock options, warrants, unvested restricted stock and unvested ZSUs. Diluted net income (loss) per share is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding, including potential dilutive securities. For periods in which we have generated a net loss or there is no income attributable to common stockholders, we do not include stock options, warrants, unvested restricted stock and unvested ZSUs in our computation of diluted net income (loss) per share, as the impact of these awards is anti-dilutive. The net per share amounts are the same for Class A, Class B and Class C common stock because the holders of each class are legally entitled to equal per share distributions whether through dividend or distribution. Further, as we assume the conversion of Class B and Class C common shares into Class A common shares for the Class A diluted net income (loss) per share computation, the net income (loss) is equal to total net income (loss) for that computation. The following table sets forth the computation of basic and diluted net income (loss) per share of common stock (in thousands, except per share data): Three Months Ended March 31, 2016 2015 Class Class Class Class Class Class A B C A B C (unaudited) BASIC: Net income (loss) attributable to common stockholders $ (22,471 ) $ (3,461 ) $ (626 ) $ (39,525 ) $ (5,909 ) $ (1,062 ) Weighted-average common shares outstanding 737,061 113,515 20,517 763,658 114,169 20,517 Basic net income (loss) per share $ (0.03 ) $ (0.03 ) $ (0.03 ) $ (0.05 ) $ (0.05 ) $ (0.05 ) DILUTED: Net income (loss) attributable to common stockholders $ (22,471 ) $ (3,461 ) $ (626 ) $ (39,525 ) $ (5,909 ) $ (1,062 ) Reallocation of net income (loss) as a result of conversion of Class C shares to Class A shares (626 ) — — (1,062 ) — — Reallocation of net income (loss) as a result of conversion of Class B shares to Class A shares (3,461 ) — — (5,909 ) — — Net income (loss) attributable to common stockholders-diluted $ (26,558 ) $ (3,461 ) $ (626 ) $ (46,496 ) $ (5,909 ) $ (1,062 ) Weighted-average common shares outstanding-basic 737,061 113,515 20,517 763,658 114,169 20,517 Conversion of Class C to Class A common shares outstanding 20,517 — — 20,517 — — Conversion of Class B to Class A common shares outstanding 113,515 — — 114,169 — — Weighted-average common shares outstanding-diluted 871,093 113,515 20,517 898,344 114,169 20,517 Diluted net income (loss) per share $ (0.03 ) $ (0.03 ) $ (0.03 ) $ (0.05 ) $ (0.05 ) $ (0.05 ) The following weighted-average equity awards were excluded from the computation of diluted net income (loss) per share because their effect would have been anti-dilutive for the periods presented (in thousands): Three Months Ended March 31, 2016 2015 Stock options and employee stock purchase plan 22,985 38,798 Restricted shares 5,504 11,129 ZSUs 63,758 68,127 Total 92,247 118,054

Per the terms of our amended agreement, we paid additional up-front fees of $0.3 million to be amortized over the remaining extended term of the loan. The interest rate for the amended credit facility is determined based on a formula using certain market rates, as described in the amended credit agreement. Additionally, our minimum quarterly commitment fee was reduced from $0.6 million per quarter to $0.1 million per quarter based on the portion of the credit facility that is not drawn down. The agreement requires us to comply with certain covenants, including maintaining a minimum capitalization ratio, and maintaining a minimum cash balance. As of March 31, 2016, we had not drawn down any amounts under the credit facility and were in compliance with these covenants. Legal Matters On July 30, 2012, a purported securities class action captioned DeStefano v. Zynga Inc. et al In re Zynga Inc. Securities Litigation The lead plaintiff filed a First Amended Complaint on March 31, 2014. The First Amended Complaint alleges that the defendants violated the federal securities laws by issuing false or misleading statements regarding the Company’s business and financial projections. The plaintiffs seek to represent a class of persons who purchased or otherwise acquired the Company’s securities between February 14, 2012 and July 25, 2012. The First Amended Complaint asserts claims for unspecified damages, and an award of costs and expenses to the putative class, including attorneys’ fees. On March 25, 2015, the Court issued an order denying the defendants’ motion to dismiss the First Amended Complaint. On April 28, 2015, the Court denied the defendants’ motion for leave to seek reconsideration of that order. On June 12, 2015, the Court entered a scheduling order setting certain pretrial deadlines leading up to a hearing on any dispositive motions scheduled for May 12, 2017. On June 24, 2015, pursuant to a stipulation among the parties, the consolidated class actions were reassigned to Magistrate Judge Jacqueline Scott Corley for all further proceedings. Pursuant to court order, a mediation session was conducted before the Honorable Edward Infante (Ret.) on August 4, 2015. The parties reached an agreement in principle to settle In re Zynga Inc. Securities Litigation In addition, a purported securities class action captioned Reyes v. Zynga Inc., et al On April 4, 2013, a purported class action captioned Lee v. Pincus, et al On June 24, 2015, certain of the defendants filed a motion for relief from the court’s November 14, 2014 decision denying the defendants’ motion to dismiss the complaint. Briefing on the motion for relief from the court’s November 14, 2014 decision is complete. A hearing date has not been set. On August 19, 2015 the parties agreed to voluntarily dismiss three individual director defendants from the case. Plaintiff filed a motion for class certification on July 13, 2015, and, after briefing was completed, the court held a hearing on plaintiff’s motion on November 20, 2015. On December 30, 2015, the court granted plaintiff’s motion for class certification. The court has not yet entered a schedule for further proceedings in this action. Although it is reasonably possible that our assessment of the possibility of loss could change in the near term due to one or more confirming events, the Company believes it has meritorious defenses in the Lee v. Pincus Since August 3, 2012, nine stockholder derivative lawsuits have been filed in State or Federal courts in California and Delaware purportedly on behalf of the Company against certain current and former directors and executive officers of the Company. The derivative plaintiffs allege that the defendants breached their fiduciary duties and violated California Corporations Code section 25402 in connection with our initial public offering in December 2011, secondary offering in April 2012, and allegedly made false or misleading statements regarding the Company’s business and financial projections. Beginning on August 3, 2012, three of the actions were filed in San Francisco County Superior Court. On October 2, 2012, the court consolidated those three actions as In re Zynga Shareholder Derivative Litigation Beginning on August 16, 2012, four stockholder derivative actions were filed in the United States District Court for the Northern District of California. On December 3, 2012, the court consolidated these four actions as In re Zynga Inc. Derivative Litigation On April 4, 2014, a derivative action was filed in the Court of Chancery of the State of Delaware captioned Sandys v. Pincus, et al. The derivative actions include claims for, among other things, unspecified damages in favor of the Company, certain corporate actions to purportedly improve the Company’s corporate governance, and an award of costs and expenses to the derivative plaintiffs, including attorneys’ fees. We believe that the plaintiffs in the derivative actions lack standing to pursue litigation on behalf of Zynga. Because the derivative actions are in the early stages of the litigation process, we are not in a position to assess whether any loss or adverse effect on our financial condition is probable or remote or to estimate the range of potential loss, if any. The Company is, at various times, also party to various other legal proceedings and claims which arise in the ordinary course of business. In addition, we may receive notifications alleging infringement of patent or other intellectual property rights. Adverse results in any such litigation, legal proceedings or claims may include awards of substantial monetary damages, costly royalty or licensing agreements, or orders preventing us from offering certain games, features, or services, and may also result in changes in our business practices, which could result in additional costs or a loss of revenue for us and could otherwise harm our business. Although the results of such litigation cannot be predicted with certainty, we believe that the amount or range of reasonably possible losses related to such pending or threatened litigation will not have a material adverse effect on our business, operating results, cash flows, or financial condition should such litigation be resolved unfavorably. We recognize legal expenses as incurred.

Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying consolidated financial statements are presented in accordance with United States generally accepted accounting principles (“U.S. GAAP”). The consolidated financial statements include the operations of us and our wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in the consolidation. The accompanying interim consolidated financial statements and these related notes should be read in conjunction with the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2015.
Unaudited Interim Financial Information	Unaudited Interim Financial Information The accompanying interim consolidated balance sheet as of March 31, 2016, the interim consolidated statements of operations, the interim consolidated statements of comprehensive income (loss) for the three months ended March 31, 2016 and 2015, the interim consolidated statements of cash flows for the three months ended March 31, 2016 and 2015 and the related footnote disclosures are unaudited. These unaudited consolidated interim financial statements have been prepared in accordance with U.S. GAAP. In management’s opinion, the unaudited consolidated interim financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments of a normal recurring nature necessary for the fair presentation of the Company’s statement of financial position and operating results for the periods presented. The results for the three months ended March 31, 2016 are not necessarily indicative of the results expected for the full fiscal year or any other future period.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and notes thereto. Significant estimates and assumptions reflected in the financial statements include, but are not limited to, the estimated lives of virtual goods that we use for revenue recognition, useful lives of property and equipment and intangible assets, accrued liabilities, income taxes, accounting for business combinations, stock-based expense and evaluation of goodwill, intangible assets, and long-lived assets for impairment. Actual results could differ materially from those estimates. Changes in our estimated average life of durable virtual goods during the three months ended March 31, 2016 for various games resulted in an increase in revenue and income from operations of $2.6 million, which is the result of adjusting the remaining recognition period of deferred revenue generated in prior periods at the time of a change in estimate. We also recognized $1.3 million of revenue and income from continuing operations in the three months ended March 31, 2016 due to changes in our estimated average life of durable virtual goods for games that have been discontinued as there is no further service obligation after the closure of these games. These changes in estimates resulted in a $0.01 per share impact on our reported earnings per share for the three months ended March 31, 2016.
