AB 831 was signed by California Governor Newsom in 2025. The legislation made the operation of sweepstakes casinos illegal in the Golden State, effective January 1st, 2026.
Only pure social casino models and mystery box websites remain legal.
Stakester’s Take
With the passing of AB831, California no longer allows operators of online sweepstakes games (defined broadly to include dual‑currency models) or any financial institution, technology provider, platform services, content suppliers, payment processors, or media affiliates that knowingly support sweepstakes activity in California.
Violations carry penalties of up to $25,000 and/or one year in county jail.
California has long been one of the strictest states on gambling, with online real-money casinos, online poker for real money, online sports betting, real money bingo and now sweepstakes casinos (under the dual-currency prize model) all explicitly prohibited.
What Gambling Is Legal in California?
While online casinos are not legal, California still offers a range of regulated gambling options.
Legal gambling activities in California include:
- Tribal Casinos: Operated on Native American land, these are the primary legal venues for casino-style gaming, including slots and table games.
- Cardrooms: Licensed establishments offering poker and certain player-banked games.
- California State Lottery: Includes draw games, scratch cards, and other state-run lottery products.
- Horse Racing & Pari-Mutuel Betting: Legal at licensed racetracks and approved off-track betting facilities.
- Charitable Gaming: Includes bingo and raffle-style fundraising activities under specific regulations.
Many players look for online alternatives that offer similar entertainment value without violating state law, which is where social-style platforms come into consideration.
Online Alternatives
In California today, mystery box sites or pure social casinos could be considered legal as they are built around entertainment-only play and do not depend on the same prize-redemption model as sweepstakes casinos.
Platforms such as HorsePlay, Hard Rock Social Casino, and Card Crush are available in California as pure social casino or mystery box sites.

California Gambling Oversight
The California Gambling Control Commission (CGCC) and the Bureau of Gambling Control (BGC) are the primary regulators for legal gambling activities within the state. While these agencies focus on licensing and oversight of land-based card rooms, tribal casinos, and gaming vendors, they do not regulate sweepstakes casinos directly.
Because sweepstakes platforms fall outside traditional gambling definitions, thanks to their free entry mechanisms, they are not subject to the same licensing or tax requirements. Still, they must comply with consumer protection standards and ensure all promotional sweepstakes laws are followed.
For more information, residents can visit the CGCC’s official site or consult the California Gambling Law, Regulations, and Resource Guide for detailed insights into legal definitions and regulatory structures.
The Future of Online Gaming in California
Near-term, AB 831 closes the sweepstakes-casino lane (effective January 1, 2026).
Long-term, California still hasn’t resolved online gambling expansion, largely due to competing stakeholder interests and the state’s existing structure around tribal gaming and cardrooms.
For players, that means the online “casino-style” market shifts back to retail-only legal play or niche alternatives as detailed above, unless a future statewide iGaming framework emerges.
Latest California Sweepstakes Casino Regulatory Changes
California’s biggest sweepstakes update was AB 831. The law targeted online sweepstakes games that mimic real-money casino play through virtual currency systems, and it took effect on January 1, 2026.
That is the main regulatory change users need to understand. California sweepstakes searches now point to a legal-status answer, not an availability or comparison answer.
