The problem provably fair solves
In a traditional casino game you cannot inspect the shuffle. Provably fair systems fix this with cryptography: the platform commits to its randomness before you play, and hands you the tools to verify the result after. Cheating would require breaking a hash function, not just fudging a number.
The three ingredients
- Server seed — the platform's secret random value; its hash is shown to you before the round.
- Client seed — your value, which you can change at any time; the platform cannot predict it.
- Nonce — a counter that increments each round, so identical seeds never repeat a result.
How a verified round works
- Before the round, the game shows the hash of the server seed — a fingerprint that locks it in.
- Your client seed and nonce are combined with the server seed to produce the result.
- After rotation, the server seed is revealed. Hash it yourself: it must match the fingerprint from step 1.
- Recompute the round with both seeds — the outcome must reproduce exactly.
Where to try it on ProFair
The Provably Fair hub walks through live verification for ProFair Originals games like Crash, Dice, Mines and Plinko — every round's seeds and hashes are available for inspection. It is the same transparency standard used by the world's leading crypto casinos.
Frequently asked questions
Does provably fair mean I win more?
No — it proves results are untampered; the stated house edge still applies. Fairness and favourability are different things.
Can ProFair change a result after I bet?
Not without breaking the committed hash — that is the whole point of publishing it before the round.
Do I need to be technical to verify?
No. The verification panel does the hashing for you; understanding the three ingredients above is enough.
