Before the spin, we generate a random 32-byte secret and publish only its hash.

commitment = SHA256(serverSecret)

Entries are sorted by join ticket ID. Each winner slot gets a roll from the secret, draw reference, and slot number.

roll = SHA256(serverSecret + drawRef + slot)[0:8] → 0.00–99.99

After the live spin we publish the secret. This page reruns the same steps and checks the winner list.

SHA256(revealedSecret) === commitment

Join tickets are random IDs assigned when someone enters. The secret stays hidden until the spin finishes, then anyone can check the result here.
