How provably fair works
Before you bet, the site commits to a secret server seed by showing you its hash. Your client seed and a counter (nonce) are combined with it to generate the result. After the seed is revealed, you can recompute every result and confirm the site couldn't have changed it. Our free case works the same way; try the verifier on our provably fair page.
