Provably Fair

Every round is verifiable, before and after.

How it works

  1. 1. Server seed: A 32-byte random secret generated when the round is created.
  2. 2. Server seed hash: SHA-256 of the seed, published before the round starts so we cannot change it later.
  3. 3. Nonce: Monotonic round number.
  4. 4. Crash point: HMAC-SHA256(seed, nonce). First 13 hex characters are converted to a number and mapped to a multiplier with 3% house edge.
  5. 5. Reveal: After each round ends, the server seed is published — anyone can verify the crash.
