Provably fair

Check the rounds yourself: once a seed is revealed, your browser can replay the rounds that used it.

How a round is decided

  1. Before you play, we show you the SHA-256 hash of our secret server seed. It is a fingerprint: we cannot change the seed later without the fingerprint changing.
  2. You choose a client seed (or keep the one we made). Every round also has a counter, the nonce.
  3. The result is computed from HMAC-SHA256(server seed, client seed : nonce : block), turned into a number without bias.
  4. When you start a new seed pair, we reveal the old server seed. Your browser then replays the rounds that used it (the latest 50 are loaded) and checks both the fingerprint and each result.
