The Nevada Gaming Commission on Thursday will consider slapping the Caesars Entertainment Inc.-owned William Hill sportsbook with a $100,000 fine, following a four-count complaint filed in August by the Nevada Gaming Control Board.

The Control Board accused William Hill of violating gaming regulations by failing to promptly resolve a system failure that affected more than 50,000 bettors since 2015.

In the complaint signed Aug. 19, the Control Board alleged that the company’s CBS Race and Sports Book mobile wagering system produced duplicate wagers on some sports bets. When bettors complained to the company about the duplicate wagers in June 2021, the company failed to report it to regulators.
