How it works

Every bet result is determined by three values: the server seed (committed to you as a hash before play), your client seed, and a nonce.

After you reveal your server seed, the casino can no longer change it — and you (or anyone) can re-compute the outcome from those three values plus the game's published algorithm.

This page is that algorithm, running in your browser. You can read the source, save the page, and run it offline.

Algorithms and source

Every game's verifier is a self-contained JavaScript function. The source you see here is the source that ran when you clicked Verify.
