Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation and Use of EstimatesThe accompanying unaudited consolidated condensed financial statements of Caesars have been prepared under the rules and regulations of the Securities and Exchange Commission (the “SEC”) applicable for interim periods, and therefore, do not include all information and footnotes necessary for complete financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”). The results for the interim periods reflect all adjustments (consisting primarily of normal recurring adjustments) that management considers necessary for a fair presentation of financial position, results of operations, and cash flows.

We consolidate all subsidiaries in which we have a controlling financial interest and variable interest entities (“VIEs”) for which we or one of our consolidated subsidiaries is the primary beneficiary. Control generally equates to ownership percentage, whereby (i) affiliates that are more than 50% owned are consolidated; (ii) investments in affiliates of 50% or less but greater than 20% are generally accounted for using the equity method where we have determined that we have significant influence over the entities; and (iii) investments in affiliates of 20% or less are generally accounted for using the cost method. We review our investments for VIE consideration if a reconsideration event occurs to determine if the investment continues to qualify as a VIE. If we determine an investment no longer qualifies as a VIE, a gain or loss may be recognized upon deconsolidation.
Segment Reporting, Policy [Policy Text Block]	We view each property as an operating segment and aggregate such properties into three regionally-focused reportable segments: (i) Las Vegas, (ii) Other U.S. and (iii) All Other, which is consistent with how we manage the business. The results of each reportable segment presented below are consistent with the way management assesses these results and allocates resources, which is a consolidated view that adjusts for the effect of certain transactions between reportable segments within Caesars. We recast previously reported segment amounts to conform to the way management assesses results and allocates resources for the current year. Net revenues are presented disaggregated by category for contract revenues separate from other revenues by segment. “All Other” includes managed, international and other properties as well as parent and other adjustments to reconcile to consolidated Caesars results.

Consolidation of Subsidiaries and Variable Interest Entities

Our consolidated financial statements include the accounts of Caesars Entertainment and its subsidiaries after elimination of all intercompany accounts and transactions.

We consolidate all subsidiaries in which we have a controlling financial interest and variable interest entities (“VIEs”) for which we or one of our consolidated subsidiaries is the primary beneficiary. Control generally equates to ownership percentage, whereby (i) affiliates that are more than 50% owned are consolidated; (ii) investments in affiliates of 50% or less but greater than 20% are generally accounted for using the equity method where we have determined that we have significant influence over the entities; and (iii) investments in affiliates of 20% or less are generally accounted for using the cost method.

We review our investments for VIE consideration if a reconsideration event occurs to determine if the investment continues to qualify as a VIE. If we determine an investment no longer qualifies as a VIE, a gain or loss may be recognized upon deconsolidation.

Segment Reporting, Policy [Policy Text Block]

We view each property as an operating segment and aggregate such properties into three regionally-focused reportable segments: (i) Las Vegas, (ii) Other U.S. and (iii) All Other, which is consistent with how we manage the business.

The results of each reportable segment presented below are consistent with the way management assesses these results and allocates resources, which is a consolidated view that adjusts for the effect of certain transactions between reportable segments within Caesars. We recast previously reported segment amounts to conform to the way management assesses results and allocates resources for the current year. Net revenues are presented disaggregated by category for contract revenues separate from other revenues by segment.

“All Other” includes managed, international and other properties as well as parent and other adjustments to reconcile to consolidated Caesars results.
