Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying interim Consolidated Financial Statements are presented for two periods, Predecessor and Successor, which relate to the accounting periods preceding and succeeding the completion of the merger of Q Merger Sub Inc., a Kansas corporation (“Merger Sub”) controlled by Apollo with and into CEC Entertainment on February 14, 2014 (the “Merger”). The Predecessor and Successor periods have been separated by a vertical line on the face of the Consolidated Financial Statements to highlight the fact that the financial information for such periods has been prepared under two different historical cost bases of accounting. For the purpose of presentation and disclosure, all references to the “Predecessor” relate to CEC Entertainment and its subsidiaries for periods prior to the Merger. All references to the “Successor” relate to CEC Entertainment and its subsidiaries, after giving effect to the Merger, for periods subsequent to the Merger. References to “CEC Entertainment,” the “Company,” “we,” “us” and “our” relate to the Predecessor for periods prior to the Merger and to the Successor for periods subsequent to the Merger. In connection with our sale leaseback transaction that occurred in August 2014, the Company assigned a portion of its rights in the resulting purchase and sale agreement to a newly formed special purpose entity, a variable interest entity (“VIE”), created by a Qualified Intermediary to facilitate a like-kind exchange pursuant to Internal Revenue Code Section 1031. The assignment resulted in $12.1 million of the sales proceeds from the transaction being received by the VIE. We included the VIE in our Consolidated Financial Statements for the fiscal year ended December 28, 2014. In February 2015, we acquired the VIE, along with its capital improvements and remaining cash balance. The assets, liabilities and operating results of the acquired VIE are not material to our Consolidated Financial Statements. The Company has a controlling financial interest in International Association of CEC Entertainment, Inc. (the “Association”), a VIE. The Association primarily administers the collection and disbursement of funds (the “Association Funds”) used for advertising, entertainment and media programs that benefit both us and our franchisees. We and our franchisees are required to contribute a percentage of gross sales to these funds and could be required to make additional contributions to fund any deficits that may be incurred by the Association. We include the Association in our Consolidated Financial Statements, as we concluded that we are the primary beneficiary of its variable interests because we (a) have the power to direct the majority of its significant operating activities; (b) provide it unsecured lines of credit; and (c) own the majority of the stores that benefit from the Association’s advertising, entertainment and media expenditures. The assets, liabilities and operating results of the Association are not material to our Consolidated Financial Statements. Because the Association Funds are required to be segregated and used for specified purposes, we do not reflect franchisee contributions to the Association Funds as revenue, but rather record franchisee contributions as an offset to reported advertising expenses. Our contributions to the Association Funds are eliminated in consolidation. Contributions to the advertising, entertainment and media funds from our franchisees were $1.6 million for the nine months ended September 27, 2015, $1.5 million for the 226 day period ended September 28, 2014 and $0.4 million for the 47 day period ended February 14, 2014. The preparation of these unaudited Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of our unaudited Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Interim Financial Statements The accompanying Consolidated Financial Statements as of September 27, 2015 and for the nine months ended September 27, 2015, the 226 day period ended September 28, 2014, the 47 day period ended February 14, 2014, and the three months ended September 27, 2015 and September 28, 2014 are unaudited and are presented in accordance with the requirements for quarterly reports on Form 10-Q and, consequently, do not include all of the information and footnote disclosures required by GAAP. In the opinion of management, the Company’s Consolidated Financial Statements include all adjustments (consisting solely of normal recurring adjustments) necessary for the fair statement of its consolidated results of operations, financial position and cash flows as of the dates and for the periods presented in accordance with GAAP and the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Our Consolidated Financial Statements include all necessary reclassification adjustments to conform prior year results to the current period presentation. Consolidated results of operations for interim periods are not necessarily indicative of results for the full year. The unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended December 28, 2014, filed with the SEC on March 5, 2015.
Acquisition	The Acquisition has been accounted for as a business combination using the acquisition method of accounting, whereby the purchase price was allocated to tangible and intangible assets acquired and liabilities assumed, based on their estimated fair market values on the Merger date. Fair value measurements have been applied based on assumptions that market participants would use in the pricing of the asset or liability. The purchase price allocation could change in subsequent periods, up to one year from the Merger date. Any subsequent changes to the purchase price allocation that result in material changes to our Consolidated Financial Statements will be adjusted retroactively.
Property and Equipment	Asset Impairments During the three and nine months ended September 27, 2015, we recognized an asset impairment charge of $0.9 million primarily related to ten stores. There were no impairment charges recognized in the three months ended September 28, 2014, the 226 day period ended September 28, 2014 and the 47 day period ended February 14, 2014. We continue to operate all of these stores. These impairment charges were the result of a decline in the stores’ financial performance, primarily due to various economic factors in the markets in which the stores are located. As of September 27, 2015, the aggregate carrying value of the property and equipment at impaired stores, after the impairment charges, was $0.7 million for stores impaired in 2015.
Recently Issued Accounting Guidance	Recently Issued Accounting Guidance Accounting Guidance Not Yet Adopted: In January 2015, the FASB issued ASU 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20). This amendment eliminates the income statement concept of extraordinary items and the requirements for entities to consider whether an underlying event or transaction is extraordinary. This amendment is effective for fiscal years beginning after December 15, 2015, including interim periods therein. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. We do not expect the adoption of this amendment to have a significant impact on our Consolidated Financial Statements. In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. This amendment requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this amendment. This amendment is effective for fiscal years beginning after December 15, 2015, including interim periods therein. The amendment should be applied on a retrospective basis, wherein the balance sheet of each individual period should be adjusted to reflect the period-specific effects of applying the new guidance. Early adoption is permitted for financial statements that have not been previously issued. As of September 27, 2015, we have $21.1 million of net deferred financing costs that would be reclassified from a long-term asset to a reduction in the carrying amount of our debt. In August 2015, the FASB issued ASU 2015-14, Revenue From Contracts With Customers (Topic 606): Deferral of the Effective Date. This amendment defers the effective date of the Board’s revenue standard, ASU 2014-09. The amendment defers the effective date of ASU 2014-09 to annual reporting periods beginning after December 15, 2017 and for interim periods therein. Early application is permitted, but only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods therein. We are currently assessing the impact of adopting this new guidance on our Consolidated Financial Statements. In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. This amendment requires that an acquirer must recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The effect on earnings of changes in depreciation or amortization, or other income effects (if any) as a result of the change to the provisional amounts, calculated as if the accounting had been completed as of the acquisition date, must be recorded in the reporting period in which the adjustment amounts are determined rather than retrospectively. This amendment is effective for fiscal years beginning after December 15, 2015, including interim periods therein. Early adoption is permitted for financial statements that have not been previously issued. We do not expect the adoption of this amendment to have a significant impact on our Consolidated Financial Statements.
