Sweepstakes Casinos & Social Sportsbooks
Sweepstakes casinos and social sportsbooks are not real-money sportsbooks. They use a virtual-currency model, which is why many are available in states without legal online betting. They are listed here in their own dedicated section, separate from licensed betting brands.
Social sportsbooks like Fliff and Onyx Odds operate under sweepstakes laws rather than state betting licenses, so they are available in many states where traditional online sportsbooks are not. You predict real games using virtual currencies, and sweeps coins can be redeemed for prizes under each product's own rules. Always confirm eligibility and minimum age where you live.

How the sweepstakes model works
Sweepstakes and social products use a dual virtual-currency model rather than direct real-money wagering, which is why they are available in many states where traditional sportsbooks are not. Players use a free play currency and a promotional sweeps currency that can, under each product’s own rules, be redeemed for prizes. Because they are not sportsbooks, we list them separately throughout this site. Always review the product’s own terms and confirm eligibility in your state.
Social sportsbooks vs. sweepstakes casinos
Both run on the same legal model; the difference is the product. A social sportsbook like Fliff or Onyx Odds focuses on sports predictions, with markets on major U.S. leagues that feel similar to a sportsbook app. A sweepstakes casino like Stake.us focuses on casino-style games. If sports are what you care about and your state has no legal sportsbook, a social sportsbook is usually the closer fit, and you can also compare prediction markets as another alternative.
