DonutVault Provably Fair
Before you bet, we show you the hash of the server seed deciding your rounds. We cannot change that seed afterwards without the hash changing. Rotate the pair and we reveal the seed itself — then you can replay every round it decided, right here, and check we did not touch it. House edge is 2.0%, applied the same way to every game.

Paste a revealed server seed, the client seed it ran with, and a round number. This recomputes the roll in your browser — if it matches what we recorded, that outcome was fixed before you played.
