What Zonko’s Rules Say

Zonko is a social casino owned and operated by Mamba Limited, a company incorporated in the Isle of Man. Games are played with Gold Coins, which have no prize value, and Sweepstakes Coins, which the sweepstakes rules say cannot be bought and may be redeemed for prizes. Mamba publishes the same terms and sweepstakes rules on its other brands' sites.

The sweepstakes are open to legal US residents aged 18 or over outside 14 restricted states: California, Connecticut, Delaware, Idaho, Indiana, Louisiana, Maine, Michigan, Montana, Nevada, New Jersey, New York, Tennessee and Washington. The terms of use (last updated September 17, 2026) list the same states. Players in Florida are limited to a 5,000 SC maximum win on a single play.

Free Sweepstakes Coins come from the daily bonus, missions, prize drops, scratchcards, social media promotions and a handwritten mail-in request, which credits 3 SC per valid request card. Gold Coin purchases may also include free SC. Coins must be played once before they count toward a redemption. Cash prizes start at 100 qualifying SC, at US$1 per coin. The rules say prizes are paid to a bank account in the player's name, while the FAQ says redemptions go to a debit card registered in the player's name. Identity, age and payment-method checks come first.

The rules allow one redemption request every 48 hours, a pending review period of up to 3 business days, and a possible limit of US$2,000 per day and US$40,000 per rolling 30 days. Sweepstakes Coins expire after 60 days without Sweepstakes Coin play.
