Account verification is a standard procedure sweepstakes casinos deploy to ensure only eligible players (users from supported states, players who meet the legal gambling age requirements, etc.) are playing. Online casinos, on the other hand, typically offer upward of 3,000+ titles, including slots and popular table games like blackjack, poker, baccarat, Sic Bo, and many others. Another important factor to consider, especially when you’re comparing sweepstakes casino bonuses, is the currency conversion rate. That’s why sweepstakes casinos use virtual currency (SC) that is exclusively giftable via promotions or GC purchases, which can be redeemed for real money prizes (or gift cards) after all the bonus rules have been met.

They must be wagered a certain number of times (1-3x in most casinos), and a minimum redemption threshold (typically 50 or 100 SC) must be met before they become cashable. Gold Coins are the free-play currency used to play for fun while Sweeps Coins are the equivalent of “bonus funds”. While social casinos only use Gold Coins as their primary currency, sweepstakes casinos have spiced things up with “Sweeps Coins”, which hold monetary value and can be redeemed for cash prizes. In terms of gaming, sweeps casinos often have the same games you’d see in online casinos from reputable i-gaming vendors like Relax Gaming, Hacksaw, or Yggdrasil.
