Check a result yourself

Every winner is the first eight characters of SHA-256(seed:game), read as a number, mod 15, plus one. Paste the seed and the game ID from the results page and your browser does the maths. Nothing is sent to us.

Paste the seed and the game ID, then press Check.

Why this works

Before a room fills, only the hash of the seed is shown. A hash cannot be run backwards, so nobody, including us, can pick a seed that lands on a chosen number after seeing who holds which slot. After the spin the seed is published and anyone can confirm it hashes to what was shown, and that it produces the winner.
