Accounting Policies [Abstract]
Revenue recognition and Promotional allowances	Revenue recognition and Promotional allowances Gaming revenue is the net difference between gaming wagers and payouts for prizes from VGMs, non-subsidized free play and accruals related to the anticipated payout of progressive jackpots. Progressive jackpots contain base jackpots that increase at a progressive rate based on the credits played and are charged to revenue as the amount of the jackpots increase. The Company recognizes gaming revenues before deductions of such related expenses as NYSGC’s share of VGM revenue and the Monticello Harness Horsemen’s Association (the “MHHA”) and Agriculture and New York State Horse Breeding Development Fund’s contractually required percentages. Food, beverage, racing and other revenue, includes food and beverage sales, racing revenue earned from pari-mutuel wagering on live harness racing and simulcast signals to and from other tracks and miscellaneous income. The Company recognizes racing revenues before deductions of such related expenses as purses, stakes and awards. Some elements of the racing revenues from Off-Track Betting Corporations (“OTBs”) are recognized as collected, due to uncertainty of receipt of and timing of payments. Net revenues are recognized net of certain sales incentives in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Certification (“ASC”) 605-50, “Revenue Recognition—Customer Payments and Incentives”. The retail value of complimentary food, beverage and other items provided to the Company’s guests is included in gross revenues and then deducted as promotional allowances. The estimated cost of providing such food, beverage and other items as promotional allowances is included in food, beverage, racing and other expense. In addition, promotional allowances include non-subsidized free play offered to the Company’s guests based on their relative gaming worth and prizes included in certain promotional marketing programs.
Principles of consolidation	Principles of consolidation The condensed consolidated financial statements include Empire’s accounts and their wholly-owned subsidiaries. All significant inter-company balances and transactions are eliminated in consolidation.
Accounts receivable	Accounts receivable Accounts receivable, net of allowances, are stated at the amount the Company expects to collect. When required, an allowance for doubtful accounts is recorded based on information on the collectability of specific accounts. Accounts are considered past due or delinquent based on contractual terms, how recently payments have been received and the Company’s judgment of collectability. In the normal course of business, the Company settles wagers for other racetracks and is exposed to credit risk. These wagers are included in accounts receivable. Account balances are charged against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.
Deferred lease costs	Project Development Costs Because the Company’s application for a Gaming Facility License was submitted in a competitive environment and the Company could not be certain it would be awarded a Gaming Facility License, all costs incurred for the Development Projects were expensed until the Company was awarded a Gaming Facility License on December 21, 2015. As a result of being awarded the Gaming Facility License, the Company began capitalizing the expenditures on the Development Projects during the fourth quarter of 2015.
Earnings (loss) per common share	Loss per common share The Company computes basic loss per share by dividing net loss applicable to common shareholders by the weighted-average common shares outstanding for the period. Diluted loss per share reflects the potential dilution of earnings that could occur if securities or contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the loss of the entity. Since the effect of common stock equivalents is anti-dilutive with respect to losses, these common stock equivalents have been excluded from the Company’s computation of loss per common share. Therefore, basic and diluted loss per common share for the years ended March 31, 2016 and 2015 are the same.
Fair value	Fair value The Company follows the provisions of ASC 820, “Fair Value Measurement,” issued by the FASB for financial assets and liabilities. This standard defines fair value, provides guidance for measuring fair value, requires certain disclosures and discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow) and the cost approach (cost to replace the service capacity of an asset or replacement cost). The Company chose not to elect the fair value option as prescribed by FASB, for its financial assets and liabilities that had not been previously carried at fair value. The Company’s financial instruments are comprised of current assets, current liabilities and a long-term loan. Current assets and current liabilities approximate fair value due to their short-term nature.
Stock-based compensation	Stock-based compensation The cost of all share-based awards to employees, including grants of employee stock options and restricted stock, is recognized in the financial statements based on the fair value of the awards at grant date. The fair value of stock option awards is determined using the Black-Scholes valuation model on the date of grant. The fair value of restricted stock awards is equal to the market price of Empire’s common stock on the date of grant. The fair value of share-based awards is recognized as stock-based compensation expense on a straight-line basis over the requisite service period from the date of grant.
Income taxes	Income taxes The Company applies the asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in future taxable or deductible amounts, based on enacted tax laws and rates for the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.
Estimates and assumptions	Estimates and assumptions The preparation of financial statements in conformity with 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 the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from estimates.
Recent accounting pronouncements	Recent accounting pronouncements In May 2014, the FASB issued new revenue recognition guidance, which will supersede nearly all existing revenue recognition guidance. The core principle of the guidance is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve the core principle, the new guidance implements a five-step process for customer contract revenue recognition. The guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenues and cash flows arising from contracts with customers. The new guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, and early adoption is prohibited. On July 9, 2015, the FASB reaffirmed the guidance in its April 29, 2015 proposed Accounting Standards Update ("ASU") that defers the effective date of the new revenue recognition standard by one year and allows early adoption as of the original effective date. Entities can transition to the new guidance either retrospectively or as a cumulative-effect adjustment as of the date of adoption. Management is assessing the impact that the new revenue recognition guidance will have on the consolidated financial statements. In February 2016, FASB issued ASU 2016-02, Leases (Topic 842) ("ASU 2016-02"), which provides guidance for accounting for leases. Under ASU 2016-02, the Company will be required to recognize the assets and liabilities for the rights and obligations created by leased assets. ASU 2016-02 will take effect for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted. The Company is currently evaluating its leases against the requirements of this pronouncement. In March 2016, FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09"), which provides guidance for accounting for share based compensation for employees. Under ASU 2016-09, several aspects of the accounting for share-based payment award transactions are simplified, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 will take effect for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. Management is assessing the impact that the new stock compensation guidance will have on the consolidated financial statements.
