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”) is a leading provider of social game services. We develop, market and operate social games as live services played on mobile platforms such as iOS and Android and social networking sites such as Facebook. Generally, all of our games are free to play, and we generate revenue through the in-game sale of virtual goods and advertising services. 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, India 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, 2016. Unaudited Interim Financial Information The accompanying interim consolidated balance sheet as of March 31, 2017, the interim consolidated statements of operations, the interim consolidated statements of comprehensive income (loss) for the three months ended March 31, 2017 and 2016, the interim consolidated statements of cash flows for the three months ended March 31, 2017 and 2016 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 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, 2017 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. In the first quarter of 2017, there were no changes in our estimated average life of durable virtual goods or discontinued games that required adjusting the recognition period of deferred revenue generated in prior periods. In the first quarter of 2016, changes in our estimated average life of durable virtual goods for various games resulted in an increase in revenue and income from operations of $2.6 million, which was 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 operations in the first quarter of 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 had a $0.01 per share impact on our reported earnings per share in the first quarter of 2016. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “ Revenue from Contracts with Customers (Topic 606), Revenue Recognition (Topic 605) Based on our initial assessment, the impact of the application of the new standard will likely result in a change in timing of our revenue recognition for software licensing related to NaturalMotion technology, which is currently recognized as revenue over time, rather than at a point in time. Under the new standard, we will be required to estimate the standalone selling price of software licenses separate from any associated maintenance services and recognize revenue for the license when control is transferred. While software licensing related to NaturalMotion is not material to our revenue, this will likely result in an acceleration in revenue recognition compared to the current method. Another key change in the standard that impacts our revenue recognition relates to the explicit collectability threshold a contract must meet before revenue can be recognized. For certain advertising arrangements where we have assessed that collectability is not reasonably assured due to unfavorable payment terms or a history of slow collections, the current practice is to defer revenue recognition until payment is received. However, under the new standard, we will be required to make an assessment of collectability at the inception of the contract and if deemed probable for collection, recognize revenue as advertisements are delivered, which will result in an acceleration in revenue recognition compared to the current method. While we are still completing our assessment for the population of advertisers under consideration, we do not expect this change to have a material impact on our revenue. We are currently in the process of evaluating other possible impacts on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” In March 2016, the FASB issued ASU 2016-09, “ Stock Compensation (Topic 718): Improvements to Employee Shared-Based Payment Accounting 97.3 In August 2016, the FASB issued ASU 2016-15, “ Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments,” which provides guidance on specific issues related to how certain cash receipts and cash payments are classified in the statement of cash flows, with the objective of reducing diversity in practice. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017 and early adoption is permitted. We will adopt the standard in the first quarter of 2018 and are currently in the process of evaluating the impact on our consolidated financial statements and related disclosures. In November 2016, the FASB issued ASU 2016-18, “ Statement of Cash Flows (Topic 230): Restricted Cash,” This guidance is effective for interim and annual reporting periods beginning after December 31, 2017 and early adoption is permitted We will adopt the standard in the first quarter of 2018 and are currently in the process of evaluating the impact on our consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU 2017-01, “ Business Combinations (Topic 805) Clarifying the Definition of a Business,”

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	2. Fair Value Measurements Our financial instruments consist of cash equivalents and accounts receivable. Accounts receivable, net is stated at its carrying value, which approximates fair value. Cash equivalents, consisting of money market funds 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 Zindagi Games, Inc. (“Zindagi”) and PuzzleSocial, Inc. (“PuzzleSocial”). The amounts payable are contingent upon the achievement of certain performance targets. 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. We recorded the change in estimated fair value of the contingent consideration liabilities for our acquisitions as a net benefit of $0.1 million in the first quarter of 2017 within research and development expense in our consolidated statement of operations. In the first quarter of 2016, we acquired Zindagi. Under the terms of the acquisition agreement, the contingent consideration of up to $60.0 million 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. As of March 31, 2017, the current contingent consideration liability is $0.2 million. There was no change in the estimated fair value of the contingent consideration liability from December 31, 2016. In the third quarter of 2016, we acquired PuzzleSocial. Under the terms of the acquisition agreement, the contingent consideration of up to $42.0 million may be payable based on the achievement of certain future performance targets during the two and a half 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. As of March 31, 2017, the current contingent consideration liability is $0.6 million, reflecting a $0.1 million decrease in the estimated fair value of the contingent consideration liability from December 31, 2016. 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, 2017 Level 1 Level 2 Level 3 Total Assets: Money market funds (1) $ 379,050 $ — $ — $ 379,050 Corporate debt securities (1) — 201,083 — 201,083 Total $ 379,050 $ 201,083 $ — $ 580,133 Liabilities: Contingent consideration $ — $ — $ 807 $ 807 December 31, 2016 Level 1 Level 2 Level 3 Total Assets: Money market funds (1) $ 439,330 $ — $ — $ 439,330 U.S. government and government agency debt securities — 19,987 — 19,987 Corporate debt securities (1) — 269,768 — 269,768 Total $ 439,330 $ 289,755 $ — $ 729,085 Liabilities: Contingent consideration $ — $ — $ 901 $ 901 (1) Includes amounts classified as cash and cash equivalents.

Earnings Per Share [Abstract]
Net Income (Loss) Per Share of Common Stock	10. 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 (on a one-to-one basis) 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, 2017 2016 Class Class Class Class Class Class A B C A B C (unaudited) BASIC: Net income (loss) attributable to common stockholders $ (8,356 ) $ (896 ) $ (222 ) $ (22,471 ) $ (3,461 ) $ (626 ) Weighted-average common shares outstanding 772,364 82,831 20,517 737,061 113,515 20,517 Basic net income (loss) per share $ (0.01 ) $ (0.01 ) $ (0.01 ) $ (0.03 ) $ (0.03 ) $ (0.03 ) DILUTED: Net income (loss) attributable to common stockholders $ (8,356 ) $ (896 ) $ (222 ) $ (22,471 ) $ (3,461 ) $ (626 ) Reallocation of net income (loss) as a result of conversion of Class C shares to Class A shares (222 ) — — (626 ) — — Reallocation of net income (loss) as a result of conversion of Class B shares to Class A shares (896 ) — — (3,461 ) — — Net income (loss) attributable to common stockholders-diluted $ (9,474 ) $ (896 ) $ (222 ) $ (26,558 ) $ (3,461 ) $ (626 ) Weighted-average common shares outstanding-basic 772,364 82,831 20,517 737,061 113,515 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 82,831 — — 113,515 — — Weighted-average common shares outstanding-diluted 875,712 82,831 20,517 871,093 113,515 20,517 Diluted net income (loss) per share $ (0.01 ) $ (0.01 ) $ (0.01 ) $ (0.03 ) $ (0.03 ) $ (0.03 ) 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, 2017 2016 Stock options and employee stock purchase plan 35,905 22,985 Restricted shares 1,417 5,504 ZSUs 52,932 63,758 Total 90,254 92,247

Pincus, 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. 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. On July 27, 2016, the court entered a scheduling order setting a trial date of October 9, 2017. Before the trial date, a mediation session was conducted on September 20, 2016 where the parties reached an agreement in principle to settle Lee v. Pincus, et al. Derivative Litigation Since August 3, 2012, eight 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 and our secondary offering in April 2012 by allegedly making 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 U.S. 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. 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. As discussed above, on February 3, 2017, Mayer et al. v. Zynga On March 31, 2017, Umrao Mayer, George Simmons, Zindagi, and Cam Tech Building, LLC initiated an arbitration with JAMS against the Company. In its Statement of Claims, the claimants assert five claims for relief, including Breach of Contracts, Breach of the Implied Covenant of Good Faith and Fair Dealing, Estoppel, Conversion, and Declaratory Relief with Respect to Unlawful Non-Competition and Non-Solicitation Agreements. The primary allegations made by the claimants are that the Company breached an Asset Purchase Agreement dated December 30, 2015 (the “Zindagi Acquisition Agreement”) by failing to provide the claimants an opportunity to achieve an earnout payment, is unlawfully withholding an escrow payment due under the Zindagi Acquisition Agreement, improperly terminated Messrs. Mayer and Simmons on November 29, 2016, breached a lease agreement, and required Messrs. Mayer and Simmons to enter into unlawful employment agreements. The claimants assert that they are entitled to compensatory damages in excess of $60 million, the release of $875,000 plus interest being held in escrow, exemplary damages, damages for the remaining lease payments, declaratory relief, and attorneys’ fees and costs. On May 1, 2017, the Company filed its response, including a general denial of the allegations and a counterclaim for $2.5 million due to the termination of Messrs. Mayer and Simmons for “Cause” under the Zindagi Acquisition Agreement. The Company is also seeking its attorneys’ fees and costs. While there can be no assurance of favorable outcomes, the Company believes it has a meritorious counterclaim and defenses and will vigorously defend this action, and, accordingly, believes a loss, while possible, is not probable for this action. Other 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, 2016.
Unaudited Interim Financial Information	Unaudited Interim Financial Information The accompanying interim consolidated balance sheet as of March 31, 2017, the interim consolidated statements of operations, the interim consolidated statements of comprehensive income (loss) for the three months ended March 31, 2017 and 2016, the interim consolidated statements of cash flows for the three months ended March 31, 2017 and 2016 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 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, 2017 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. In the first quarter of 2017, there were no changes in our estimated average life of durable virtual goods or discontinued games that required adjusting the recognition period of deferred revenue generated in prior periods. In the first quarter of 2016, changes in our estimated average life of durable virtual goods for various games resulted in an increase in revenue and income from operations of $2.6 million, which was 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 operations in the first quarter of 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 had a $0.01 per share impact on our reported earnings per share in the first quarter of 2016.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “ Revenue from Contracts with Customers (Topic 606), Revenue Recognition (Topic 605) Based on our initial assessment, the impact of the application of the new standard will likely result in a change in timing of our revenue recognition for software licensing related to NaturalMotion technology, which is currently recognized as revenue over time, rather than at a point in time. Under the new standard, we will be required to estimate the standalone selling price of software licenses separate from any associated maintenance services and recognize revenue for the license when control is transferred. While software licensing related to NaturalMotion is not material to our revenue, this will likely result in an acceleration in revenue recognition compared to the current method. Another key change in the standard that impacts our revenue recognition relates to the explicit collectability threshold a contract must meet before revenue can be recognized. For certain advertising arrangements where we have assessed that collectability is not reasonably assured due to unfavorable payment terms or a history of slow collections, the current practice is to defer revenue recognition until payment is received. However, under the new standard, we will be required to make an assessment of collectability at the inception of the contract and if deemed probable for collection, recognize revenue as advertisements are delivered, which will result in an acceleration in revenue recognition compared to the current method. While we are still completing our assessment for the population of advertisers under consideration, we do not expect this change to have a material impact on our revenue. We are currently in the process of evaluating other possible impacts on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” In March 2016, the FASB issued ASU 2016-09, “ Stock Compensation (Topic 718): Improvements to Employee Shared-Based Payment Accounting 97.3 In August 2016, the FASB issued ASU 2016-15, “ Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments,” which provides guidance on specific issues related to how certain cash receipts and cash payments are classified in the statement of cash flows, with the objective of reducing diversity in practice. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017 and early adoption is permitted. We will adopt the standard in the first quarter of 2018 and are currently in the process of evaluating the impact on our consolidated financial statements and related disclosures. In November 2016, the FASB issued ASU 2016-18, “ Statement of Cash Flows (Topic 230): Restricted Cash,” This guidance is effective for interim and annual reporting periods beginning after December 31, 2017 and early adoption is permitted We will adopt the standard in the first quarter of 2018 and are currently in the process of evaluating the impact on our consolidated financial statements and related disclosures.
