Fairness

Provably fair

Crunchy Originals rounds are generated from a server seed, your client seed and an incrementing nonce. The server seed is hashed and shown before you play, so it cannot be changed afterwards.

Verify a round

How it works

  1. 1. A server seed is generated and its SHA-256 hash is published to you.
  2. 2. You set or accept a client seed, which you can change at any time.
  3. 3. Each round uses HMAC-SHA256(server seed, client seed:nonce).
  4. 4. The hash is converted to a number between 0 and 1 and mapped to the outcome.
  5. 5. Rotating your seed reveals the old server seed so you can check every round.

How verification works today

The server generates and stores seeds, publishes the hash before play, records every nonce, and reveals the seed only on rotation, with third-party RNG certification.
