Is CardCrush legal in California?
Operational — AB 831 monitoring
California's AB 831 restricts dual-currency sweepstakes models, which is why national brands like Stake.us and McLuck exited the state. CardCrush operates via a single-currency skill-contest carve-out; verify its current compliance posture before depositing.

The short answer
CardCrush operates legally in California today, but on a legal theory no California court has ruled on. CardCrush uses one currency, Mystery Coins, as both the play unit and the prize unit, which it argues sits outside AB 831's dual-currency prohibition. CardCrush holds an 8.6/10 Crush score and ranks first among the four card-sweepstakes brands available in California.
The one open risk is enforcement. A California regulator or court could test the single-currency carve-out at any time. Until that happens, CardCrush remains available to California players who verify the current status first.
What AB 831 changed in California
Governor Gavin Newsom signed California AB 831 on October 11, 2025, and the law took effect on January 1, 2026. AB 831 added Section 337o to the California Penal Code, making it unlawful to operate or promote a dual-currency online sweepstakes game in California. AB 831 defines the prohibited model as a purchasable non-redeemable currency paired with a separately earned redeemable currency.
AB 831 carries penalties of $1,000 to $25,000 per violation, up to one year in county jail, classified as a misdemeanor. AB 831 also extends liability beyond operators to payment processors, financial institutions, gaming content suppliers, geolocation providers, and media affiliates. That broad liability chain is why more than 20 sweepstakes brands exited California around the January 1, 2026 effective date.
Why CardCrush still operates in California
CardCrush uses a single-currency skill-contest model, which is the basis for its continued California operation. CardCrush issues one currency, Mystery Coins, valued at 1 MC to $1, that serves as both the play currency and the redeemable prize currency. AB 831 targets the dual-currency structure, where a separate non-redeemable coin funds play, so CardCrush argues its single-currency design is outside the statute.
That argument is a legal theory, not a court ruling. No California court has tested whether CardCrush's single-currency model clears Section 337o. CardCrush therefore carries genuine regulatory uncertainty, and California players should treat the AB 831 question as unresolved before depositing.
Card sweepstakes brands legal in California (ranked)
Four card and casino sweepstakes brands operate legally in California as of June 10, 2026, each clearing AB 831 by a different route. CrushCards ranks all four on the same fixed-weight rubric.
Horseplay and GiddyUp run federal Advance Deposit Wagering models that preempt AB 831, the most durable basis of the four. CardCrush relies on the untested single-currency carve-out. ClubWPT Gold operates under a contested Game Days policy that caps redeemable play to roughly nine days per month.
Brands that exited California
More than 20 dual-currency sweepstakes brands exited California on or before AB 831's January 1, 2026 effective date. The notable exits below all ran the Gold Coins plus Sweeps Coins model that AB 831 prohibits.
Modo.us took a middle path, keeping free Gold Coin play in California but disabling Sweeps Coin redemption. California players who lost access to these dual-currency brands moved to CardCrush, Horseplay, and GiddyUp for real-prize play.
Age, redemption, and safe play in California
California players must meet a minimum age of 18, with 21 required at some brands. CardCrush and the other surfaced brands require KYC identity verification before any redemption. Redemption thresholds and methods vary by brand, so confirm each brand's terms before depositing.
Real-prize gaming carries financial risk regardless of legal status. California players should set limits and treat the AB 831 question as unresolved. Anyone who needs support can call the problem-gambling helpline at 1-800-522-4700.
The bottom line
CardCrush is legal and operational in California as of June 10, 2026, under a single-currency skill-contest model that argues it sits outside AB 831. The theory is untested in California court, so CardCrush carries an AB 831 monitoring status and real regulatory uncertainty. CardCrush ranks first of the four card-sweepstakes brands available in California, ahead of Horseplay, GiddyUp, and ClubWPT Gold. California players should verify CardCrush's current compliance posture before depositing.
California FAQ
Is CardCrush legal in California?
CardCrush operates legally in California as of June 10, 2026, under a single-currency skill-contest model. CardCrush argues that model falls outside AB 831's dual-currency prohibition, but no California court has ruled on the theory. Verify current status before depositing.
Why didn't CardCrush leave California like Stake.us and McLuck?
Stake.us and McLuck used the dual-currency model AB 831 prohibits, so both exited California in late December 2025. CardCrush uses a single currency, Mystery Coins, as both play and prize unit, which it argues is outside the ban. That structural difference is why CardCrush stayed.
Which card sweepstakes brands are legal in California?
Four brands operate legally in California: CardCrush, Horseplay, GiddyUp, and ClubWPT Gold. Horseplay and GiddyUp use federal ADW parimutuel models, and ClubWPT Gold runs a contested Game Days policy. Verify each brand's terms before signing up.

California players must be at least 18, with 21 required at some brands. Each brand sets its own age gate within those limits. Identity verification through KYC is required before redemption.
Is it safe to play CardCrush in California?
CardCrush is operational and uses KYC verification, but its AB 831 legal theory is untested, so regulatory uncertainty remains. Real-prize gaming also carries financial risk. Players should verify current status, set limits, and treat the legal question as unresolved.
Will CardCrush stay legal in California?
CardCrush's California status depends on its single-currency carve-out, which a regulator or court could test at any time. No ruling exists as of June 10, 2026. CrushCards re-scores monthly and tracks the AB 831 status, so check the latest before depositing.
