Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation and Use of Estimates The 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. The results of operations for our interim periods are not necessarily indicative of the results of operations that may be achieved for the entire 2018 fiscal year.

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 (1) affiliates that are more than 50% owned are consolidated; (2) 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 (3) investments in affiliates of 20% or less are generally accounted for using the cost method.
Revenue Recognition, Policy [Policy Text Block]	We analyze our revenues based upon the type of services we provide and the geographic location of the related property. We recognize revenue when control over the goods and services we provide has transferred to the customer, which is generally when the services are performed and when we have no substantive performance obligation remaining. Sales and other taxes collected from customers on behalf of governmental authorities are accounted for on a net basis and are not included in net revenues or operating expenses.

Such complimentaries are provided in conjunction with other revenue‑earning activities and are generally provided to encourage additional customer spending on those activities. Accordingly, we allocate a portion of the transaction price we receive from such customers to the complimentary goods and services. We perform this allocation based on the SSP of the underlying goods and services, which is determined based upon the weighted-average cash sales prices received for similar services at similar points during the year.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Accounting, Policy [Policy Text Block]

Basis of Presentation and Use of Estimates

The 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”).

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 (1) affiliates that are more than 50% owned are consolidated; (2) 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 (3) investments in affiliates of 20% or less are generally accounted for using the cost method.
