Whereas real -money online casinos are legal in only a few states, sweepstakes sites can be accessed everywhere except Washington State. Are sweepstakes casinos legal in the US?īecause they don’t provide active gambling, sweepstakes casinos are not in direct violation of any federal laws on gambling. Sweepstakes casinos work on a two-currency system where one currency is for casual play only, while the other can be redeemed for monetary prizes or gift cards. Instead, you can accumulate free coins by signing up, completing daily logins, and participating in various promotions. Unlike regular online casinos, where you must deposit then wager real money to win, sweepstakes never force you to make a purchase. They do not offer real-money gambling - at least not in a direct way. Sweepstakes casinos are online platforms that enable you to play casino-style games through a sweepstakes model.
