Roulette Fairness

Our Roulette game ensures fairness through a provably fair system. Here's how it works:

• Server Seed:

  The server seed is a SHA-256 hash generated from a random 32 bytes. You can regenerate the server seed at any time. While you cannot see the original server seed immediately, you will be able to verify that it was unmodified after regenerating the server seed.

• Client Seed:

  The client seed is generated for the user in the same way as the server seed. As the client seed affects every spin result, you can change it to any seed of your choice at any time, ensuring that it is impossible for us to manipulate the results.

• Nonce:

  The nonce is a number that starts at 0 and increments by 1 for each spin. This prevents the deterministic nature of the SHA-256 function from being abused. Each spin done using the same server seed and client seed pair is paired with a different nonce.

The SHA-256 function we use to generate the roll is deterministic, meaning that if the client seed is combined with the same server seed, it will generate the same roll result every time. To prevent this from being abusable, we pair each roll with a different nonce.

The SHA-256 function returns the hash value for the seed combination in a hex-encoded form. We take the first 8 characters of this hash and convert them into a decimal number. To ensure fairness, we take this number modulo 37, resulting in a final number between 0 and 36. This final number is the outcome used in the game.

Each spin can be verified using this formula once you have revealed your server seed for the previous spins. The published unhashed server seeds can be checked by applying the SHA-256 function to them, which will produce the previously published hashed version of the server seed. This ensures that the server seed was not modified. Each user can check the integrity of every spin made using this information.
