Verify a prize draw

You do not have to trust us. Pick a draw below and press «Verify» — your own browser recalculates the winners from public data and shows whether they match.

  1. Before the draw the game publishes a fingerprint (hash) of its secret number. After the draw the number itself is revealed — it must give the same fingerprint, so it could not be swapped.
  2. Public randomness: the secret number is mixed with a random value of the independent drand network that nobody knew in advance — not even us. Your browser asks drand for it directly.
  3. Participants: every participant is listed under an anonymous number with their entries; only the player knows their own number.
  4. Winners: from these three things the winners are calculated by a fixed formula. If our server had changed anything, the result would not match.
