Provably fair

Before you bet, we commit to a secret server seed by showing you its SHA-256 hash. You choose the client seed, and a nonce counts your bets.

Each result comes from HMAC-SHA256(server seed, client seed:nonce). Mines are placed and cards are drawn from those bytes, so neither side can change a result after the bet.

Rotate your seed in any game's Provably fair panel to reveal the old server seed, then check any past bet: the hash must match, and the result must come out the same.

House edge: Mines 1%. Blackjack plays at about 99.1% return with perfect strategy. Max win $100,000.00 per bet.
