How provably fair games work

Typical flow: the operator commits to a server seed (often via hash) before play; you supply or accept a client seed; a nonce increments per bet; an HMAC or hash mixes them into the outcome. After rotation, the server seed is revealed so you can recompute.

  1. Commitment published (hash of server seed).
  2. Bets resolved with client seed + nonce.
  3. Server seed revealed; recompute and compare.

Next: verify a result.
