Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Basis of Presentation The accompanying consolidated financial statements of the Company have been prepared by Scientific Games Corporation and are unaudited. When used in these notes, the terms "we," "us," "our" and the "Company" refer to Scientific Games Corporation and all entities included in our consolidated financial statements unless otherwise specified or the context otherwise indicates. In the opinion of management, all adjustments necessary to present fairly our consolidated financial position as of September 30, 2013, our results of operations and comprehensive income for the three and nine months ended September 30, 2013 and 2012, and our cash flows for the nine months ended September 30, 2013 and 2012 have been made. Such adjustments are of a normal, recurring nature. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") have been condensed or omitted. All monetary values set forth in these financial statements are in United States dollars ("USD" or "$") unless otherwise stated herein. Unless otherwise noted or apparent from the context, the disclosures presented in this Quarterly Report on Form 10-Q do not reflect our acquisition of WMS, which occurred on October 18, 2013. These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our 2012 Annual Report on Form 10-K. Interim results of operations are not necessarily indicative of results of operations for a full year. On March 25, 2013, we completed the sale of our installed base of gaming terminals in our pub business to Gamestec Leisure Limited (a subsidiary of Astra Games Limited) ("Gamestec") as discussed in Note 2 of the Notes to Consolidated Financial Statements in this Quarterly Report on Form 10-Q. The results of the discontinued pub operations for the three and nine months ended September 30, 2013 and 2012 are presented herein in accordance with Accounting Standards Codification ("ASC") 205-20, Presentation of Financial Statements - Discontinued Operations. Significant Accounting Policies We describe our significant accounting policies in Note 1 of the Notes to Consolidated Financial Statements in our 2012 Annual Report on Form 10-K. There have been no changes to our significant accounting policies during the nine months ended September 30, 2013, except as discussed below. Our policy is to periodically review the estimated useful lives of our fixed assets. Our review during the three months ended June 30, 2013 indicated lower estimated useful lives for our gaming terminals deployed to our U.K. licensed betting office ("LBO") customers relative to historical estimates due to recent market changes that we believe have impacted the replacement cycle of these terminals. As a result, effective April 1, 2013, we revised the estimated useful lives of our gaming terminals currently deployed to our LBO customers. This change increased depreciation expense by an immaterial amount for the three and nine months ended September 30, 2013. Recently Issued Accounting Guidance In December 2011, the Financial Accounting Standards Board (the "FASB") issued guidance enhancing disclosure requirements about the nature of an entity's right to offset and related arrangements associated with its financial instruments and derivative instruments. The new guidance requires the disclosure of the gross amounts subject to rights of set-off, amounts offset in accordance with the accounting standards followed, and the related net exposure. In January 2013, the FASB clarified that the scope of this guidance applies to derivatives, including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset or subject to an enforceable master netting arrangement, or similar agreements. The new guidance became effective for us beginning January 1, 2013. The adoption of this guidance did not have a material impact on our financial position or results of operations. In February 2013, the FASB issued guidance on presentation of comprehensive income to improve the reporting of reclassifications out of accumulated other comprehensive income. The guidance requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. The adoption of this guidance did not have a material impact on our financial statements as we did not have any material reclassifications out of accumulated other comprehensive income for the three and nine months ended September 30, 2013. In February 2013, the FASB amended guidance related to the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date. The guidance requires an entity to measure obligations resulting from such arrangements as the sum of the amount the reporting entity agreed to pay pursuant to its agreement with its co-obligors and any additional amount it expects to pay on behalf of such co-obligors. In addition, the amendment requires an entity to disclose the nature and amount of the obligation as well as other information about the obligation. The guidance is effective for interim and annual periods beginning after December 15, 2013 and is to be applied retrospectively. The adoption of this guidance is not expected to have a material impact on our financial position or results of operations. In March 2013, the FASB amended guidance related to a parent company's accounting for the release of the cumulative translation adjustment into net income upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. This guidance is effective for fiscal periods beginning after December 15, 2013, and is to be applied prospectively to derecognition events occurring after the effective date. The adoption of this guidance is not expected to have a material impact on our financial position or results of operations. In July 2013, the FASB issued guidance on the presentation of unrecognized tax benefits. The guidance requires an entity to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. However, to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with a deferred tax asset. The guidance is effective for fiscal years beginning after December 15, 2013 and interim periods within those years. The adoption of this guidance is not expected to have a material impact on our financial position or results of operations. In July 2013, the FASB issued guidance which permits the Fed Funds Effective Swap Rate to be used as a U.S. benchmark interest rate for hedge accounting purposes, in addition to the U.S. government rate and LIBOR. We adopted this guidance effective September 30, 2013, and the adoption did not have an impact on our financial statements.
