How Provably Fair Works

The Seeds

Every game uses three components to generate results:

  • Server Seed - A secret random string generated by the server
  • Client Seed - Your chosen seed (you can change it anytime)
  • Nonce - A counter that increases with each bet

The Process

Before you play, we show you a Server Seed Hash (SHA256 of the server seed). This proves we can't change the seed after you see it.

After you rotate your seed with .seed newseed, we reveal the old server seed so you can verify all your previous games.

Result Hash:
HMAC-SHA256(server_seed, "client_seed:nonce")

Verification:
SHA256(server_seed) === displayed_hash
