Accounting Policies [Abstract]	'
The Company, Basis of Presentation and Summary of Significant Accounting Policies	'
	Note 1 – The Company, Basis of Presentation and Summary of Significant Accounting Policies
	Glu Mobile Inc. (the “Company” or “Glu”) was incorporated in Nevada in May 2001 and reincorporated in the state of Delaware in March 2007. The Company develops and publishes a portfolio of action/adventure and casual games designed to appeal to a broad cross section of the users of smartphones and tablet devices who download and make purchases within its games through direct-to-consumer digital storefronts, such as the Apple App Store, Google Play Store, Amazon Appstore and others (“Digital Storefronts”). The Company creates games based on its own original intellectual property, as well as third-party licensed brands.
	The Company has incurred recurring losses from operations since inception and had an accumulated deficit of $252,078 as of March 31, 2014. For the three months ended March 31, 2014, the Company generated net income of $133. The Company has in the past and may continue to incur additional operating losses and negative cash flows in the future. Failure to generate sufficient revenues, reduce spending or raise additional capital could adversely affect the Company’s ability to achieve and sustain profitability and its intended business objectives.
	Principles of Consolidation and Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles (“GAAP”) in the United States for complete financial statements and 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, 2013 filed with the SEC on March 14, 2014. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting only of normal recurring adjustments, which the Company believes are necessary for a fair statement of the Company’s financial position as of March 31, 2014 and its unaudited condensed consolidated results of operations for the three months ended March 31, 2014 and 2013, respectively. These unaudited condensed consolidated financial statements are not necessarily indicative of the results to be expected for the entire year. The unaudited condensed consolidated balance sheet presented as of December 31, 2013 has been derived from the audited consolidated financial statements as of that date, and the unaudited condensed consolidated balance sheet presented as of March 31, 2014 has been derived from the unaudited condensed consolidated financial statements as of that date.
	The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated.
	Concentration of Credit Risk
	Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents and accounts receivable.
	The Company derives its accounts receivable from revenues earned from customers or through Digital Storefronts located in the U.S. and other locations outside of the U.S. The Company performs ongoing credit evaluations of its customers’ and the Digital Storefronts’ financial condition and currently does not require any collateral from its customers or the Digital Storefronts. The Company bases its allowance for doubtful accounts on management’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company reviews past due balances over a specified amount individually for collectability on a monthly basis. The Company writes off accounts receivable balances against the allowance when it determines that the amount will not be recovered.
	The following table summarizes the revenues from customers or aggregate purchases through Digital Storefronts that accounted for more than 10% of the Company’s revenues for the periods indicated:
		Three Months Ended
		March 31,
		2014			2013
	Apple		50.6	%		47.6	%
	Google		23.3			19.5
	At March 31, 2014, Apple Inc. (“Apple”) accounted for 48.5%, and Google Inc. (“Google”) accounted for 14.1% of total accounts receivable. At December 31, 2013, Apple accounted for 46.3%, and Jirbo (dba AdColony) and Google each accounted for 11.1% of total accounts receivable. No other customer or Digital Storefront represented more than 10% of the Company’s total accounts receivable as of these dates.
	Recent Accounting Pronouncements
	In July 2013, the FASB issued ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. Under this guidance, an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. This accounting guidance did not have a material impact on the Company’s condensed consolidated financial statements once adopted.

Earnings Per Share [Abstract]	'
Net Income (Loss) Per Share	'
	Note 2 – Net Income (Loss) Per Share
	The Company computes basic net income (loss) per share by dividing its net income (loss) for the period by the weighted average number of common shares outstanding during the period less the weighted average unvested common shares subject to restrictions imposed by the Company. Diluted net income (loss) per share reflects the potential dilution that could occur from common shares issuable through stock-based compensation plans including stock options, restricted stock units, common stock through employee stock purchase plans, warrants and contingently issuable shares. For purposes of computation of diluted net income per share for the three months ended March 31, 2014, adjustments to reported net income were not material.

Fair_Value_Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	Note 3 – Fair Value Measurements
	Fair Value Measurements
	The Company accounts for fair value in accordance with ASC 820, Fair Value Measurements and Disclosures (“ASC 820”). Fair value is defined under ASC 820 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. The Company uses a three-tier hierarchy, which prioritizes the inputs used in measuring fair value as follows:
	Level 1 - Quoted prices in active markets for identical assets or liabilities.
	Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	The first two levels in the hierarchy are considered observable inputs and the last is considered unobservable. The Company’s cash and cash equivalents, which were held in operating bank accounts, are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. As of March 31, 2014 and December 31, 2013, the Company had $36,954 and $28,496, respectively, in cash and cash equivalents. In addition, the Company’s restricted cash is classified within Level 1 of the fair value hierarchy. The carrying value of accounts receivable and payables approximates fair value due to the short time to expected receipt of payment or cash.
	Liabilities for Contingent Consideration
	On August 1, 2011, the Company completed the acquisition of Blammo Games Inc. (“Blammo”), by entering into a Share Purchase Agreement (the “Share Purchase Agreement”) by and among the Company, Blammo and each of the owners of the outstanding share capital of Blammo (the “Sellers”). Blammo is a developer of free-to-play games for the iOS platform located in Toronto, Canada. Pursuant to the terms of the Share Purchase Agreement, the Company agreed to issue to the Sellers, in the aggregate, 1,000 shares of the Company’s common stock plus up to an additional 3,313 shares of the Company’s common stock (the “Additional Shares”) if Blammo achieves certain Net Revenue (as such term is defined in the Share Purchase Agreement) targets during the fiscal years ending March 31, 2013, March 31, 2014 and March 31, 2015.
	In May 2013, the Company issued 742 shares of common stock to the former Blammo shareholders based on the Net Revenue that Blammo achieved for its fiscal year ended March 31, 2013. Since the contingency related to the number of shares earned in connection with the target for the year ended March 31, 2013 was resolved and the number of shares became fixed as of March 31, 2013, the fair value of these shares as then last re-measured in the amount of $2,263 has been presented in additional paid-in capital in the Company’s condensed consolidated balance sheet since March 31, 2013. On May 5, 2014, the Company issued 435 shares of common stock to the former Blammo shareholders based on the Net Revenue that Blammo achieved for its fiscal year ended March 31, 2014. Since the contingency related to the number of shares to be earned in connection with the target for the year ended March 31, 2014 has been resolved and the number of shares has become fixed, the fair value of these shares, as last re-measured in the amount of $2,071 has been presented in additional paid-in capital on the Company’s condensed consolidated balance sheet as of March 31, 2014. The remaining Additional Shares will be issued to the Sellers if, and to the extent that, Blammo achieves certain Net Revenue performance targets as follows for fiscal 2015 (April 1, 2014 through March 31, 2015): (a) no Additional Shares will be issued to the Sellers if Blammo does not meet its Baseline Net Revenue goal for such fiscal year and (b) up to 1,154 Additional Shares will be issued to the Sellers to the extent that Blammo exceeds its Baseline Net Revenue goal and meets its Upside Net Revenue goal for such fiscal year. To the extent that Blammo meets its Baseline Net Revenue goal for fiscal 2015 but does not meet its Upside Net Revenue goal for such fiscal year, Additional Shares will be issued to the Sellers on a straight-line basis based on the amount by which Blammo exceeded the Baseline Net Revenue goal. Blammo’s Baseline and Upside Net Revenue goals for fiscal 2015 are as follows:
	Fiscal Year	Baseline		Upside
		Net Revenue		Net Revenue
	Fiscal 2015	$	8,500	$	15,000
	Three of the five Sellers are also employees of Blammo. If any of these employee Sellers voluntarily terminates his employment with Blammo (other than because of a disability that prevents him from performing his job) or if the Company or Blammo terminates such Seller’s employment for Cause (as defined in the Share Purchase Agreement), then such Seller will be eligible to receive Additional Shares if and when such Additional Shares are earned as described above only with respect to the fiscal year in which such termination of employment occurs (and all previous fiscal years to the extent applicable), but not with respect to any Additional Shares issued in any subsequent fiscal year. In such an event, the Additional Shares that such Seller would have otherwise received will be forfeited and will not be issued by the Company or distributed to the other Sellers, but the other Sellers’ rights to receive Additional Shares will not otherwise be affected. The fair value of the contingent consideration issued to the three Sellers who are also employees of Blammo was not considered part of the purchase price, since vesting is contingent upon these employees’ continued service during the earn-out periods. The Company records the contingent consideration issued to these employees as a compensation expense over the earn-out period of one to three years. See Note 8 for further details. In accordance with ASC 805, Business Combinations, non-employee contingent consideration issued to the two Sellers who are not employees of Blammo was recorded as part of the purchase accounting and is fair valued at each subsequent reporting period. The total fair value of the non-employee contingent consideration liability has been estimated to be $50 and $68 as of March 31, 2014 and December 31, 2013, respectively. During the three months ended March 31, 2014 and 2013, the Company recorded fair value expense adjustments of $304 and $29, respectively, which represent the changes in fair value of the non-employee contingent consideration for both respective periods. In accordance with ASC 805, changes in the fair value of non-employee contingent consideration are recognized in general and administrative expense in the Company’s condensed consolidated statements of operations.
	Level 3 liabilities consist of acquisition-related liabilities for contingent consideration (i.e., earnouts) related to the acquisition of Blammo. As of March 31, 2014, the Company recorded a contingent consideration liability of $326, all of which was recorded as a current liability in accrued compensation as settlement was less than one year. As of December 31, 2013, the Company recorded a contingent consideration liability of $427, of which $329 was recorded as a current liability in accrued compensation as settlement is less than one year. The Company uses a risk-neutral framework to estimate the probability of achieving the revenue targets set forth above for each year. The fair value of the contingent consideration was determined using a digital option, which captures the present value of the expected payment multiplied by the probability of reaching the revenue targets for each year. Key assumptions for the three months ended March 31, 2014 included a discount rate of 35.0%, volatility of 42.0%, a risk-free interest rate of 0.13% and probability-adjusted revenue levels. Key assumptions for the three months ended March 31, 2013 included a discount rate of 35.0%, volatility of 36.0%, risk-free interest rates of between 0.14% and 0.25% and probability-adjusted revenue levels. Probability-adjusted revenue is a significant input that is not observable in the market, which ASC 820 refers to as a Level 3 input.

	Acquisition-related intangibles included in the above table are finite-lived and are being amortized on a straight-line basis over their estimated lives, which approximates the pattern in which the economic benefits of the intangible assets are realized. The Company has included amortization of acquired intangible assets directly attributable to revenue-generating activities in cost of revenues. The Company has included amortization of acquired intangible assets not directly attributable to revenue-generating activities in operating expenses.
	During the three months ended March 31, 2014 and 2013, the Company recorded amortization expense in the amounts of $554 and $1,074 respectively, in cost of revenues. During the three months ended March 31, 2014 and 2013, the Company recorded amortization expense in the amounts of $127 and $495, respectively, in operating expenses.
	As of March 31, 2014, the total expected future amortization related to intangible assets was as follows:

	Goodwill
	The Company has goodwill attributable to its MIG, GameSpy, Blammo and Griptonite acquisitions as of March 31, 2014. The Company attributed all of the goodwill resulting from the MIG acquisition to its Asia and Pacific (“APAC”) reporting unit. All of the goodwill attributable to the GameSpy, Blammo and Griptonite acquisitions has been fully assigned to the Company’s Americas reporting unit. The Company had fully impaired in prior years all goodwill allocated to its EMEA reporting unit. The goodwill allocated to the Americas reporting unit is denominated in U.S. Dollars (“USD”) and the goodwill allocated to the APAC reporting unit is denominated in Chinese Renminbi (“RMB”). As a result, the goodwill attributed to the APAC reporting unit is subject to foreign currency fluctuations.
	In the valuation of the goodwill balance for Griptonite, Blammo, MIG and GameSpy, the Company gave consideration to the future economic benefits of other assets that were not individually identified or separately recognized. The acquired studio workforce for each of these acquisitions was estimated to have value, and since the acquired workforce is not individually identified or separately recognized, it was subsumed within the goodwill recognized as part of each business combination. The Company further planned to leverage its preexisting contractual relationships with Digital Storefronts to distribute new titles developed by the Griptonite and Blammo studios and the expected synergies are reflected in the value of the goodwill recognized. The Company also used the GameSpy acquired workforce and expertise to help in its development efforts for its games-as-a-service (“Gaas”) technology platform, and these synergies are reflected in the value of goodwill recognized.
	Goodwill by reporting unit for the periods indicated was as follows:
		March 31, 2014																December 31, 2013
		Americas				EMEA				APAC				Total				Americas				EMEA				APAC			Total

	In accordance with ASC 350, Intangibles – Goodwill and Other (“ASC 350”), the Company’s goodwill is not amortized but is tested for impairment on an annual basis or whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. The Company performs its annual impairment review of its goodwill balance as of September 30 or more frequently if triggering events occur.
	The Company evaluates qualitative factors and overall financial performance to determine whether it is necessary to perform the first step of the multiple-step goodwill test. This step is referred to as “Step 0.” Step 0 involves, among other qualitative factors, weighing the relative impact of factors that are specific to the reporting unit as well as industry and macroeconomic factors. After assessing those various factors, if it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the entity will need to proceed to the first step of the goodwill impairment test. ASC 350 requires a multiple-step approach to testing goodwill for impairment for each reporting unit annually, or whenever events or changes in circumstances indicate the fair value of a reporting unit is below its carrying amount. The first step measures for impairment by applying the fair value-based tests at the reporting unit level. The second step (if necessary) measures the amount of impairment by applying the fair value-based tests to individual assets and liabilities within each reporting unit. The fair value of the reporting units is estimated using a combination of the market approach, which utilizes comparable companies’ data, and/or the income approach, which uses discounted cash flows.

	Note 6 – Commitments and Contingencies
	Leases
	The Company leases office space under non-cancelable operating facility leases with various expiration dates through September 2020. Rent expense for the three months ended March 31, 2014 and 2013 was $901 and $685, respectively. The terms of the facility leases provide for rental payments on a graduated scale. The Company recognizes rent expense on a straight-line basis over the lease period, and has accrued for rent expense incurred but not paid. The deferred rent balance was $1,097 and $1,131 at March 31, 2014 and December 31, 2013, respectively, and was included within other long-term liabilities.
	In April 2013 and June 2013, Company entered into lease agreements for space at its new San Francisco headquarters and Washington offices that will expire on March 31, 2018 and September 30, 2010, respectively. The Company provided deposits for letters of credit totaling $1,730 to secure its obligations under the leases, which have been classified as restricted cash on the Company’s unaudited condensed consolidated balance sheet as of March 31, 2014.
	At March 31, 2014, future minimum lease payments under non-cancelable operating leases were as follows:
		Minimum
		Operating
		Lease
	Period Ending December 31,	Payments
	2014 (remaining nine months)	$	2,882
	2015		3,918
	2016		3,306
	2017		2,604
	2018		919
	2019 and thereafter		982
		$	14,611
	Minimum Guaranteed Royalties and Developer Commitments
	The Company has entered into license and publishing agreements with various owners of brands and other intellectual property to develop and publish games for mobile devices. Pursuant to some of these agreements, the Company is required to pay minimum royalties or license fees over the term of the agreement regardless of actual game sales. Future minimum royalty payments as of March 31, 2014 were $643, which are due over the remaining nine months of 2014.
	The Company also from time to time contracts with various external software developers (“third-party developers”) to design and develop its games. The Company advances funds to these third-party developers, in installments, payable upon the completion of specified development milestones. Future developer commitments as of March 31, 2014 were $153, which are due over the remaining nine months of 2014. These developer commitments reflect the Company’s minimum cash obligations but do not necessarily represent the periods in which they will be expensed. The Company expenses developer commitments as services are provided.
	Income Taxes
	As of March 31, 2014, unrecognized tax benefits and potential interest and penalties are classified within “other long-term liabilities” on the Company’s unaudited condensed consolidated balance sheets. As of March 31, 2014, the settlement of the Company’s income tax liabilities could not be determined; however, the liabilities are not expected to become due within the next 12 months.
	Indemnification Agreements
	The Company has entered into agreements under which it indemnifies each of its officers and directors during his or her lifetime for certain events or occurrences while the officer or director is or was serving at the Company’s request in that capacity. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has a director and officer insurance policy that limits its exposure and enables the Company to recover a portion of any future amounts paid. As a result of its insurance policy coverage, the Company believes the estimated fair value of these indemnification agreements is minimal. Accordingly, the Company had recorded no liabilities for these agreements as of March 31, 2014 or December 31, 2013.
	In the ordinary course of its business, the Company includes standard indemnification provisions in most of its license agreements with carriers and other distributors. Pursuant to these provisions, the Company generally indemnifies these parties for losses suffered or incurred in connection with its games, including as a result of intellectual property infringement, viruses, worms and other malicious software, and legal or regulatory violations. The term of these indemnity provisions is generally perpetual after execution of the corresponding license agreement, and the maximum potential amount of future payments the Company could be required to make under these provisions is often unlimited. To date, the Company has not incurred costs to defend lawsuits or settle indemnified claims of these types. As a result, the Company believes the estimated fair value of these indemnity provisions is minimal. Accordingly, the Company had recorded no liabilities for these provisions as of March 31, 2014 or December 31, 2013.
	Contingencies
	From time to time, the Company is subject to various claims, complaints and legal actions in the normal course of business. The Company assesses its potential liability by analyzing specific litigation and regulatory matters using available information. The Company’s estimate of losses is developed in consultation with inside and outside counsel, which involves a subjective analysis of potential results and outcomes, assuming various combinations of appropriate litigation and settlement strategies. After taking all of the above factors into account, the Company determines whether an estimated loss from a contingency should be accrued by assessing whether a loss is deemed reasonably probable and the amount can be reasonably estimated. The Company further determines whether an estimated loss from a contingency should be disclosed by assessing whether a material loss is deemed reasonably possible. Such disclosure will include an estimate of the additional loss or range of loss or will state that an estimate cannot be made.
	In April 2013, Lodsys Group, LLC, a Texas limited liability company (“Lodsys”), filed a complaint in the U.S. District Court for the Eastern District of Texas alleging that the Company has been infringing two of Lodsys’ patents, and sought unspecified damages, including treble damages for willful infringement, interest, attorneys’ fees and such other costs as the Court may deem just and proper. On June 19, 2013, the Company filed an answer to Lodsys’s complaint (i) denying all of Lodsys’s claims, (ii) setting forth certain affirmative defenses to Lodsys’s claims and (iii) asserting counterclaims that the Company does not infringe the Lodsys patents and that the Lodsys patents are invalid. In December 2013, without admitting infringement or liability, the Company entered into a patent sub-license agreement and a settlement agreement with Lodsys to settle the dispute for an immaterial amount. In January 2014, the Court dismissed the complaint against the Company with prejudice.
	The Company does not believe it is party to any currently pending litigation the outcome of which is reasonably likely to have a material adverse effect on its operations, financial position or liquidity. However, the ultimate outcome of any litigation is uncertain and, regardless of outcome, litigation can have an adverse impact on the Company because of defense costs, potential negative publicity, diversion of management resources and other factors.

	Acquisitions
	On August 2, 2012, the Company issued an aggregate of 600 shares of its common stock to IGN in connection with the Company’s acquisition of GameSpy.
	Shares Issued in Connection with the Blammo Earnout
	In May 2013, the Company issued 742 shares to the former Blammo shareholders based on the Net Revenue that Blammo achieved for its fiscal year ended March 31, 2013. The fair value of this earnout amount has been presented in additional paid-in capital on the Company’s condensed consolidated balance sheet as of March 31, 2014. See Note 3 for more information about this issuance.
	Public Offering
	In September 2013, the Company sold in an underwritten public offering an aggregate of 7,245 shares of its common stock at a public offering price of $2.10 per share for net cash proceeds of approximately $13,985 after underwriting discounts and other offering expenses. This public offering exhausted all of the securities that the Company was able to issue under its shelf registration statement that the SEC declared effective in December 2010.
	Warrants to Purchase Common Stock
	In July 2013, the Company and MGM Interactive Inc. (“MGM”) entered into a warrant agreement that gives MGM the right to purchase up to 3,333 shares of the Company’s common stock at an exercise price of $3.00 per share (the “Warrant”), subject to certain adjustments for dividends, reorganizations and other common stock events. Of the 3,333 shares of the Company’s common stock underlying the Warrant, 333 shares were immediately vested and exercisable on the warrant agreement effective date and the remaining shares will vest and become exercisable based on conditions related to the Company releasing mobile games based on mutually agreed upon intellectual property licensed by MGM to the Company. The Warrant expires on July 15, 2018. Under ASC 505, Equity-Based Payments to Non-Employees, the Company estimated the fair value of the vested shares of the Warrant on the grant date using the Black-Scholes option valuation model and the weighted average assumptions. The Company recorded the warrant issuance as a non-cash warrant related expense in cost of revenues for warrant shares immediately vested upon signing of the agreement, as such vesting was not tied to any game release nor to any specific intellectual property license. During the three months ended March 31, 2014, the Company did not incur any expenses related to the Warrant.
	During the three months ended March 31, 2014 and 2013, respectively, investors exercised warrants to purchase 522 and 1,663 shares of the Company’s common stock, and the Company received gross proceeds of $783 and $2,495, respectively, in connection with these exercises. These exercised warrants were issued by the Company in August 2010 in connection with a private placement transaction.
	Warrants outstanding as of March 31, 2014 were as follows:
						Number

	Note 8 – Stock Option and Other Benefit Plans
	2007 Equity Incentive Plan
	In 2007, the Company’s Board of Directors adopted, and the Company’s stockholders approved, the 2007 Equity Incentive Plan (the “2007 Plan”). The 2007 Plan permits the Company to grant stock options, RSUs, and other stock-based awards to employees, non-employee directors and consultants. In April 2013, the Company’s Board of Directors approved, and in June 2013, the Company’s stockholders approved, the amended and restated 2007 Equity Incentive Plan (the “Amended 2007 Plan”). The Amended 2007 Plan includes an increase of 7,200 shares in the aggregate number of shares of common stock authorized for issuance under the plan. It also includes a fungible share provision, pursuant to which each share that is subject to a stock-based award that is not a “full value award” (restricted stock, RSUs, or other stock-based awards where the price charged to the participant for the award is less than 100% of the fair market value) reduces the number of shares available for issuance by 1.39 shares. When a stock-based award that is not a full value award is cancelled, the underlying shares are returned to the pool of shares available for grant at a ratio of 1.39 shares for each share cancelled. As of March 31, 2014, 4,385 shares were available for future grants under the Amended 2007 Plan.
	2007 Employee Stock Purchase Plan
	In 2007, the Company’s Board of Directors adopted, and the Company’s stockholders approved, the 2007 Employee Stock Purchase Plan (the “2007 Purchase Plan”). As of March 31, 2014, 1,414 shares were available for issuance under the 2007 Purchase Plan.
	2008 Equity Inducement Plan
	In March 2008, the Company’s Board of Directors adopted the 2008 Equity Inducement Plan (the “Inducement Plan”) to augment the shares available under its existing 2007 Plan. The Company has not sought stockholder approval for the Inducement Plan. As such, awards under the Inducement Plan are granted in accordance with NASDAQ Listing Rule 5635(c)(4) and only to persons not previously an employee or director of the Company, or following a bona fide period of non-employment, as an inducement material to such individuals entering into employment with the Company. The Inducement Plan initially permitted the Company to grant only nonqualified stock options, but effective November 2013, the Compensation Committee of the Company’s Board amended the Inducement Plan to permit the award of RSUs under the plan. As of March 31, 2014, 438 shares of common stock were reserved for future grants under the Inducement Plan.
	Share-Based Awards Available for Grant
	The calculation of share-based awards available for grant under the Amended 2007 Plan and the Inducement Plan for the three months ended March 31, 2014 is as follows:
			Shares
			Available
	Balances at December 31, 2013			4,890
	Increase in authorized shares			—
	Share-based awards granted (1)			(400	)
	Share-based awards canceled (2)			333
	Balances at March 31, 2014			4,823
	-1	Under the terms of the Amended 2007 Plan, RSUs granted on or after June 6, 2013 reduce the number of shares available for grant by 1.39 shares for each share subject to an RSU award.
	-2	RSUs granted after June 6, 2013 that are forfeited and returned to the pool of shares available for grant increase the pool by 1.39 shares for each share subject to an RSU that is forfeited.
	RSU Activity
	A summary of the Company’s RSU activity for the three months ended March 31, 2014, is as follows:
						Weighted
			Number of			Average
			Units			Grant Date
			Outstanding			Fair Value
	Awarded and unvested, December 31, 2013			2,578		$	2.91

	Restricted stock units expected to vest, March 31, 2014			2,186
	Stock Option Activity
	The following table summarizes the Company’s stock option activity for the three months ended March 31, 2014:
			Options Outstanding
						Weighted			Weighted
			Number			Average			Average		Aggregate
			of			Exercise			Contractual		Intrinsic
			Shares			Price			Term (Years)		Value
	Balances at December 31, 2013			10,399		$	2.98
	Options granted			48			4.92
	Options canceled			(241	)		3.65

	Balances at March 31, 2014			8,178		$	3.19			3.88	$	13,893
	Options vested and expected to vest at March 31, 2014			7,547		$	3.21			3.8	$	12,834
	Options exercisable at March 31, 2014			4,019		$	3.33			3.12	$	6,898
	The aggregate intrinsic value in the preceding table is calculated as the difference between the exercise price of the underlying awards and the quoted closing price of the Company’s common stock on The NASDAQ Global Market of $4.74 per share as of March 31, 2014 (the last trading day in the quarter). Consolidated net cash proceeds from option exercises were $4,115 and $254 for the three months ended March 31, 2014 and 2013, respectively. The Company realized no significant income tax benefit from stock option exercises during the three months ended March 31, 2014 or 2013. As required, the Company presents excess tax benefits from the exercise of stock options, if any, as financing cash flows rather than operating cash flows.
	Stock-Based Compensation
	The cost of RSUs is determined using the fair value of the Company’s common stock based on the quoted closing price of the Company’s common stock on the date of grant. RSUs typically vest and are settled over approximately a four-year period with 25% of the shares vesting on or around the one-year anniversary of the grant date and the remaining shares vesting quarterly thereafter. Compensation cost is amortized on a straight-line basis over the requisite service period.
	Under Compensation-Stock Compensation (“ASC 718”), the Company estimated the fair value of each option award on the grant date using the Black-Scholes option valuation model and the weighted average assumptions noted in the following table.
			Three Months Ended
			March 31,
			2014			2013
	Dividend yield			—	%		—	%
	Risk-free interest rate			1.2	%		0.6	%
	Expected volatility			49.6	%		53.6	%
	Expected term (years)			4			4
	The Company based its expected volatility on its own historic volatility and the historical volatility of a peer group of publicly traded entities. The expected term of options gave consideration to early exercises, post-vesting cancellations and the options’ six-year contractual term. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury Constant Maturity Rate as of the date of grant. The weighted-average fair value of stock options granted during the three months ended March 31, 2014 and 2013 was $1.94 and $1.06 per share, respectively.
	The Company calculated employee stock-based compensation expense recognized in the three months ended March 31, 2014 and 2013 based on awards ultimately expected to vest and reduced it for estimated forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates
	The following table summarizes the consolidated stock-based compensation expense by line items in the condensed consolidated statement of operations:
			Three Months Ended
			March 31,
			2014			2013
	Research and development		$	2,317		$	668
	Sales and marketing			101			67
General and administrative			561			510
Total stock-based compensation expense		$	2,979		$	1,245
The above table includes compensation expense attributable to the contingent consideration potentially issuable to the Blammo employees who were former shareholders of Blammo, which is recorded as research and development expense over the term of the earn-out periods, since these employees are primarily employed in product development. The Company re-measures the fair value of the contingent consideration each reporting period and only records a compensation expense for the portion of the earn-out target that is likely to be achieved. In addition, the Company is exposed to potential continued fluctuations in the fair market value of the contingent consideration in each reporting period, since re-measurement is impacted by changes in the Company’s share price and the assumptions used by the Company. The Company estimated the total fair value of this liability to be $275 and $368 as of March 31, 2014 and December 31, 2013, respectively. The amount as of March 31, 2014 and March 31, 2013 excludes the 2014 and 2013 contingent consideration earnout that were classified into additional paid-in capital. See Note 3 for further details. During the three months ended March 31, 2014 and 2013, the Company recorded $1,666 and $241 of stock-based compensation expense, respectively, related to this contingent consideration.
As of March 31, 2014, the Company had $5,654 of total unrecognized compensation expense, net of estimated forfeitures, related to RSUs that will be recognized over a weighted-average period of approximately four years. As of March 31, 2014, the Company had $5,481 of total unrecognized compensation expense related to stock options, net of estimated forfeitures and excluding unvested Blammo stock-based contingent consideration expense, which will be recognized over a weighted average period of 2.52 years. As permitted by ASC 718, the Company has deferred the recognition of its excess tax benefit from non-qualified stock option exercises.

Income Taxes	'
	Note 9 – Income Taxes
	The Company recorded an income tax provision of $444 and $135 for the three months ended March 31, 2014 and 2013, respectively, primarily related to foreign income taxes. The income tax rates vary from the Federal and State statutory rates due to the valuation allowances on the Company’s net operating losses, foreign tax rate differences and withholding taxes.
	The Company estimates its annual effective tax rate at the end of each quarterly period and records the tax effect of certain discrete items, which are unusual or occur infrequently, in the interim period in which they occur. In addition, jurisdictions with a projected loss for the year or a year-to-date loss where no tax benefit can be recognized and jurisdictions where a reliable estimate of ordinary income cannot be made are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter depending on the mix and timing of actual earnings versus annual projections. The Company’s ability to use its net operating loss carryforwards and federal and state tax credit carryforwards to offset future taxable income and future taxes, respectively, may be subject to restrictions attributable to equity transactions that result in changes in ownership as defined by Internal Revenue Code Section 382.
	The Company accounts for uncertain tax positions in accordance with ASC 740, Income Taxes. As of March 31, 2014 and December 31, 2013, the total amount of unrecognized tax benefits was $6,550 and $6,538, respectively. As of March 31, 2014 and December 31, 2013, approximately $1,927 and $1,915, respectively, of unrecognized tax benefits, if recognized, would impact the Company’s effective tax rate. The remaining balance, if recognized, would adjust the Company’s deferred tax assets, each of which are subject to a valuation allowance. As of March 31, 2014, the Company anticipated that the liability for uncertain tax positions, excluding interest and penalties, could decrease by approximately $1,290 within the next twelve months due to the expiration of certain statutes of limitation in foreign jurisdictions in which the Company does business.
	The Company’s policy is to recognize interest and penalties related to unrecognized tax benefits in income tax expense. The Company recorded $18 and $40 of interest on uncertain tax positions during the three months ended March 31, 2014 and 2013, respectively. As of March 31, 2014 and December 31, 2013, the Company had a liability of $298 and $283, respectively, related to interest and penalties for uncertain tax positions.
	The Company is subject to taxation in the United States and various foreign jurisdictions. The material jurisdictions subject to examination by tax authorities are primarily the State of California, United States, United Kingdom, Canada, and China. The Company’s federal and California tax returns are open by statute for tax years 2002 and forward and could be subject to examination by the tax authorities. The statute of limitations for the Company’s 2011 and 2012 tax returns for the various entities in the United Kingdom is expected to be closed in 2014. The Company’s China income tax returns are open by statute for tax years 2008 and forward.

Segment Reporting [Abstract]	'
Segment Reporting	'
	Note 10 – Segment Reporting
	ASC 280, Segment Reporting, establishes standards for reporting information about operating segments. It defines operating segments as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision-maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision-maker is its Chief Executive Officer. The Company’s Chief Executive Officer reviews selected financial information on a geographic basis; however this information is included within one operating segment for purposes of allocating resources and evaluating financial performance.
	Accordingly, the Company reports as a single reportable segment—mobile games. For purposes of enterprise-wide disclosures, the Company attributes revenues to geographic areas based on the country in which the distributor’s, advertising service provider’s or carrier’s principal operations are located. In the case of Digital Storefronts, revenues are attributed to the geographic location where the end-user makes the purchase. The Company generates its revenues in the following geographic regions:

	MGM Warrant
	On April 1, 2014, the Company entered into a license agreement with MGM Interactive Inc., United Artists Corporation and Danjaq, LLC pursuant to which the Company will develop and publish a free-to-play mobile game based on the James Bond film franchise. The commercial release by the Company of this mobile game, which is expected to occur in summer 2015, will trigger the vesting of 1,000 shares subject to the warrant that the Company previously issued to MGM Interactive in July 2013.
	PlayFirst Acquisition
	On April 30, 2014, the Company entered into an Agreement and Plan of Merger with PlayFirst, Inc., a Delaware corporation (“PlayFirst”), Midas Acquisition Corp., a Delaware corporation and wholly owned subsidiary of the Company (“Sub”), and Fortis Advisors LLC, as Stockholders’ Agent (the “Merger Agreement”). Pursuant to the Merger Agreement, Sub will merge with and into PlayFirst in a statutory reverse triangular merger (the “Merger”"), with PlayFirst surviving the Merger as a wholly owned subsidiary of the Company. PlayFirst, which is based in San Francisco, California, employs approximately 30 people and develops casual games for smartphones and other mobile devices.
	If the Merger is consummated, at the closing of the Merger (the “Closing”) (a) the Company will issue to certain of PlayFirst’s stockholders, in exchange for all of the issued and outstanding shares of PlayFirst, a total of 3,000 shares of the Company’s common stock, of which 1,500 shares will be held back by the Company for 24 months to satisfy indemnification claims under the Merger Agreement; and (b) the Company will assume up to $3,550 of PlayFirst debt. Of the 3,000 shares that the Company will issue in the Merger, up to 450 of such shares will be issued to certain PlayFirst employees, one-half of which will be included in the hold back described in the preceding sentence. The total shares that the Company will issue in the Merger is subject to reduction in the event, and to the extent, that PlayFirst’s closing balance sheet reflects a negative net working capital position. All outstanding PlayFirst stock options and warrants will be cancelled at the Closing.
	The Merger Agreement contains customary representations, warranties and covenants of each of the parties. The consummation of the Merger is subject to approval by PlayFirst’s stockholders and various other closing conditions. Certain stockholders of PlayFirst, holding a sufficient number of shares of PlayFirst’s capital stock to approve the Merger, have entered into agreements with the Company to vote their shares in favor of the Merger. Either the Company or PlayFirst may terminate the Merger Agreement if the Closing does not occur before May 30, 2014 or July 28, 2014, subject to certain limited exceptions.
	Universal Shelf Registration Statement
	On April 30, 2014, the Company filed a universal shelf registration statement with the Securities and Exchange Commission. The universal shelf registration statement, if and when declared effective by the Securities and Exchange Commission, will permit the Company to publicly offer and sell, from time to time, up to $150,000 of various types of debt and equity instruments, including common stock, preferred stock, debt securities and warrants. The Company currently intends to use the net proceeds from any sale of securities pursuant to the universal shelf registration statement for general corporate purposes including, without limitation, additions to the Company’s working capital, capital expenditures and potential acquisitions of, or investments in, companies and technologies that complement the Company’s business. Any issuances of securities under the universal shelf registration statement will require the filing of a prospectus supplement identifying the amount and terms of the securities to be issued and the expected use of the net proceeds from such sale.

	Principles of Consolidation and Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles (“GAAP”) in the United States for complete financial statements and 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, 2013 filed with the SEC on March 14, 2014. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting only of normal recurring adjustments, which the Company believes are necessary for a fair statement of the Company’s financial position as of March 31, 2014 and its unaudited condensed consolidated results of operations for the three months ended March 31, 2014 and 2013, respectively. These unaudited condensed consolidated financial statements are not necessarily indicative of the results to be expected for the entire year. The unaudited condensed consolidated balance sheet presented as of December 31, 2013 has been derived from the audited consolidated financial statements as of that date, and the unaudited condensed consolidated balance sheet presented as of March 31, 2014 has been derived from the unaudited condensed consolidated financial statements as of that date.

Concentration of Credit Risk	'
	Concentration of Credit Risk
	Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents and accounts receivable.
	The Company derives its accounts receivable from revenues earned from customers or through Digital Storefronts located in the U.S. and other locations outside of the U.S. The Company performs ongoing credit evaluations of its customers’ and the Digital Storefronts’ financial condition and currently does not require any collateral from its customers or the Digital Storefronts. The Company bases its allowance for doubtful accounts on management’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company reviews past due balances over a specified amount individually for collectability on a monthly basis. The Company writes off accounts receivable balances against the allowance when it determines that the amount will not be recovered.
	The following table summarizes the revenues from customers or aggregate purchases through Digital Storefronts that accounted for more than 10% of the Company’s revenues for the periods indicated:

At December 31, 2013, Apple accounted for 46.3%, and Jirbo (dba AdColony) and Google each accounted for 11.1% of total accounts receivable. No other customer or Digital Storefront represented more than 10% of the Company’s total accounts receivable as of these dates.

	In July 2013, the FASB issued ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. Under this guidance, an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. This accounting guidance did not have a material impact on the Company’s condensed consolidated financial statements once adopted.

Computation of Net Income (Loss) Per Share	'
	The Company computes basic net income (loss) per share by dividing its net income (loss) for the period by the weighted average number of common shares outstanding during the period less the weighted average unvested common shares subject to restrictions imposed by the Company. Diluted net income (loss) per share reflects the potential dilution that could occur from common shares issuable through stock-based compensation plans including stock options, restricted stock units, common stock through employee stock purchase plans, warrants and contingently issuable shares. For purposes of computation of diluted net income per share for the three months ended March 31, 2014, adjustments to reported net income were not material.
