The range at Caesars is smaller than BetMGM, but it has around 500 games from a series of highly-rated software providers. It was formerly known as William Hill Sportsbook & Casino, but Caesars rebranded it after buying William Hill in 2021. Caesars Entertainment, Nevada-based company that owns the Caesars Palace, Eldorado, Harrah’s and Horseshoe brands, owns this user-friendly online casino.
