Fair Play

1. The odds you see are the odds you get

Every game shows its house edge and its return to player (RTP) before you bet, and those are the real figures: there are no hidden adjustments, losing streaks or “near miss” tricks. The house edge is currently 12% (an RTP of 88%) for every game except Blackjack, which has a 2% house edge (98% RTP) under its published rules. The slots reach their RTP through their published paytables, which already include the jackpot contribution. We may change a game’s edge, never above 25%, and the figure shown before you bet is always the one that applies.

2. Provably fair

Every result is fixed before you bet and can be checked afterwards. Before you play, we show a fingerprint (a SHA-256 hash) of a secret server seed. Each result is calculated from that server seed, your own client seed (which you can change at any time) and a counter that goes up by one with every bet, using HMAC-SHA256. When you rotate your seed, we reveal the old server seed, and you can check that it matches the fingerprint you were shown and recompute every result it produced, on our verifier or with any independent tool.

Crash is played by everyone together. Its results come from a published hash chain: each round’s crash point is fixed before the chain is used, and every round can be checked against the chain once it has crashed.

The Proof page also publishes a fingerprint of all our settled bets, timestamped on the Bitcoin blockchain through OpenTimestamps, so that no bet can be changed later without it being visible.

3. Limits and unfinished rounds

Unless a game shows otherwise, stakes are from 0.00001 BTC to 1 BTC and the maximum payout is 10 BTC per bet. Rounds of Mines, Chicken, Towers, Hi-Lo and Blackjack left untouched for 24 hours are finished for you by the published rule: ladder games pay what they are worth at that moment (your stake back if you made no move), and Blackjack stands.
