Yes. You can win cash prizes by playing at the sweepstakes casino sites Chumba Casino and LuckyLand. Both Chumba and LuckyLand have a well-documented history of accepting Sweeps Coins in exchange for cash prizes. You are not playing to “enter a drawing for a cash prize.” Instead, you redeem Sweeps Coins directly for cash prizes at both sites.
We do not recommend other sites, but there may be some worth considering.
