What is Provably Fair?

Provably fair is a technology that ensures online casino games are completely fair and transparent. Unlike traditional online casinos where you have to trust the operator, provably fair games use cryptographic algorithms that allow you to independently verify each game outcome.

Every bet uses three components: a server seed (from the casino), a client seed (from you), and a nonce (bet number). These are combined using HMAC-SHA256 cryptography to generate a random result that neither you nor the casino can predict or manipulate.

After each game round, the casino reveals the server seed, allowing you to verify that the outcome was determined fairly. Our tools recreate the exact same calculation the casino used, proving mathematically that the result was legitimate.
