Provably Fair

Every spin on CryptoCase is provably fair. Verify any result using our transparent cryptographic system.

How It Works

Server Seed

A secret seed generated by our server before each game. Revealed after the game ends.

Client Seed

A seed you can set yourself. Combined with the server seed to generate results.

Nonce

A counter that increases with each bet, ensuring unique results every time.

The Formula

result = SHA256(server_seed + client_seed + nonce)

The first 8 characters of the hash are converted to a number between 0 and 99.99, which determines your spin result.

Frequently Asked Questions

How do I know the results are fair?

Each game uses a combination of a server seed (which we commit to before the game) and a client seed (which you control). The result is determined by hashing these together, making it impossible for us to manipulate outcomes.

Can I change my client seed?

Yes! You can change your client seed at any time in your account settings. This gives you control over the randomness of your results.

Why is the server seed hashed before the game?

We show you a hash of the server seed before each game begins. This proves we committed to a specific seed before you played. After the game, we reveal the actual seed so you can verify it matches the hash.

What is the nonce?

The nonce is a number that increases with each bet you make. This ensures that even with the same seeds, each bet produces a unique result.
