Coinflip →server seed, client seed, nonce + hashed server seedcasino's own codecodesandbox.io
The casino shows you the hash of a secret server seed before you bet; you add your own client seed and a nonce that counts your bets. Once you rotate the pair, the server seed is revealed and every bet on it can be recomputed.

Hash chain3 games, from a round hash from a pre-committed chain

Hash chain
GameInputsVectorsAlgorithm source
Crash →game hash + client seed (salt), previous rounds to listcasino's own codecodesandbox.io
Slide →game hash, client seed (salt) + previous rounds to listcasino's own codecodesandbox.io
Roulette →game hash + client seed (salt), previous rounds to listcasino's own codecodesandbox.io
Every round comes from one long chain of hashes made before launch. The casino publishes the last link in advance; hashing a round backwards reaches it, and a salt chosen after the commitment (a Bitcoin or Ethereum block hash) turns each link into a result.
