How do I verify a game result was fair?
Outcomes are committed to with a cryptographic hash you can check yourself from the game history.
You can check any result yourself.
How it works
Before a round, the outcome is committed to with a cryptographic hash published in advance. It cannot be changed afterward without the change being obvious.
The inputs are:
- A server seed
- Your client seed
- A nonce that increments each round
After the round the server seed is revealed. If it produces the published hash, the outcome was fixed before you played.
Check a result
- Open the game history for the round.
- Note the server seed hash, revealed server seed, your client seed, and the nonce.
- Run them through an independent verifier for the algorithm.
Use a third-party verifier. A check you run with our own calculator proves less than one you run with someone else’s.
Change your client seed
Set your own in the game settings. Since your seed is one of the inputs, setting it yourself rules out outcomes being arranged in advance for your account.
Poker
Poker shuffles use the same underlying random number generation, independently certified by a third-party testing house.
