Provably fair is a cryptographic system that lets you verify every single game result is legitimate and unmanipulated. No trust required — you can prove it yourself.
🔑 How It Works
Every provably fair result is generated using two inputs:
Fair Result = Server Seed (Hashed) + Client Seed
1. Server Seed (Casino's Input)
Before each game round, Gamba generates a server seed and provides you with a hashed version of it. This hash locks in the casino's input before you play — meaning we can't change it after the fact.
2. Client Seed (Your Input)
You provide your own client seed, which influences the outcome. This ensures you have a direct impact on every result.
3. Verification
After playing, the unhashed server seed is revealed so you can verify that the result matches. This holds the casino accountable — if anything was changed, the hashes won't match.
