What does “Provably Fair” mean?
All games at Duel Casino use “Provably Fair”. This means you can verify that each bet produced a random and unpredictable result.
How does it work?
Before each round, the game creates:
- Server seed: a random string generated by the platform
- Client seed: a random string you provide
- Nonce: a number that increases with each bet
Before you place a bet, the platform shows a SHA-256 hash of the server seed. This lets you confirm later that the server seed was not changed after the result was generated. The game then combines these values to produce the round outcome.
Result = Server seed + Client seed + Nonce
By using your own client seed, you take part in the input used to generate the result.
How can you verify your bets?
After the game round ends, the platform reveals the unchanged server seed. You can then check that:
- The server seed matches the original hash
- The combined seeds produced the exact result shown
- No one, including the platform, could control the outcome
