How it works

The full derivation
  1. Read the edge

    Every game prints its return and the house's edge before you bet. Dice returns 99.00%: over many bets the house keeps 1.00% of what is staked.

    return 99.00%, edge 1.00%

  2. Keep the receipt

    Before your first bet the house commits to a secret server seed by showing you its hash. Every bet then leaves a receipt: the stake, the result, the payout and that hash.

    SHA-256(server seed), shown before you bet

  3. Check it yourself

    Rotate your seed pair and the old server seed is revealed. The verifier replays any bet in your browser, with the same code the server ran.

    HMAC-SHA256(server seed, client seed:nonce:cursor)
