Three playable demos, running the real fairness code in your browser. Every deck, every spin and every winner is committed to before play starts — and you can check the maths yourself, offline, without asking us for anything.
Each demo runs the production fairness code — the same derivation, the same commitments, the same verifier. Nothing is faked for the pitch.
Players stake against each other and the wheel is built from their entries, so the house has no side to take. The winning ticket depends on a blockchain slot that had not happened when the round opened.
Play the demo →The hard case: cards must stay secret during the hand and be provable after it. Each card carries its own proof, so the river is checkable the moment it lands — and folded hands stay folded, forever.
Play the demo →The house-banked wheel, with the maths on show. Spin it as many times as you like and watch the measured return converge on the configured 96% — the edge lives in the weights, and there is nowhere else for it to hide.
Open the bench →“Provably fair” is usually one scheme stretched over every game. These are three, because the games fail in three different ways.
Nobody knows the winner while entries are still open — not even us, because the winner depends on who joins.
Hole cards have to be secret now and provable later. So the proof is split in two.
No waiting, no blockchain round trip — results land instantly and still commit in advance.
Each scheme ships with a verifier you can run yourself — in the browser, from a command line, or from a short Python script with no dependencies. They are written independently and checked against the same fixed test vectors, so if any one of them ever disagreed with the game, the build would fail before it reached you.
Player funds never touch us. Balances stay in your wallet, under your licence, and every call we make against it is idempotent — a retry can never pay twice.
Settlement is written to a durable queue before anything is sent, so a wallet outage delays a payout but cannot lose one. Refused debits are final and refunded; refused credits are retried until they land, because at that point we are holding chips that belong to a player.
