# Roobet crash

Enter the round hash from your bet's fairness details; the result is recomputed here with Roobet's own published algorithm and every step is shown. Everything runs in your browser and nothing is sent anywhere.

Hash chain casino's own code

## Where this comes from · algorithm, test vectors, notes

Algorithm Roobet's own description or verifier: [codesandbox.io](https://codesandbox.io/embed/crash-93kqwr). Scheme: hash chain.

Test vectors: casino's own code Roobet publishes no worked examples; vectors were computed by running Roobet's own verifier code from this sandbox. Source: [codesandbox.io](https://codesandbox.io/embed/crash-93kqwr).

Chain The 2,000,000th server seed, which the chain's first game used. Length 2,000,000 rounds.

**A fair result is still a result with a house edge.** Passing a check here proves the casino did not change the outcome after the bet was placed. It does not mean the odds favour the player, and no check improves them. Gambling can be harmful.
