Chumba Casino operates as a social casino that allows players to enjoy a variety of games using virtual currency. While it offers the chance to win real cash prizes through its sweepstakes model, players must purchase Gold Coins to play, which are not redeemable for cash. However, players can earn Sweeps Coins, which can be redeemed for real money. This unique structure makes Chumba Casino a legitimate option for those looking to play casino games with the potential for real cash rewards, while still adhering to legal regulations in many jurisdictions.
