Every original game at Bethropic settles from three values you can see: a server seed, your own client seed, and a nonce that counts up with each round. Together they decide the outcome, and all three are shown with the round.
Why the order matters
The server seed is committed before you bet. Because it is fixed in advance and revealed afterwards, a result cannot be chosen once your stake is known — it was already determined by seeds that existed before the round began.
Your half of it
The client seed is yours. You can change it whenever you like, and rotating it changes every outcome that follows. That is the part of the calculation the house cannot predict, which is what makes the commitment meaningful rather than ceremonial.
Checking a round
- Open the round and read the server seed, your client seed, and the nonce.
- Feed those three values back through the same calculation the game used.
- The number that comes out is the result you were given — or the round did not settle the way it claimed.
What it does not promise
Provable fairness says the result was not tampered with. It does not change the odds: a game with a 99% return still keeps 1% over time, and verifying a round confirms the draw was honest, not that it was in your favour.
Every original also accepts a 0 bet, so you can watch the whole mechanism work without staking anything.
Try it on any Bethropic original — the seeds and nonce show up with every round.
