How to verify a Scratch result
The first number picks the card’s prize by its published weight, out of 100,000; the rest only arrange the symbols. Every card is decided before you scratch. The numbers come from your seeds: f = the first 52 bits of HMAC-SHA256(server seed, “client seed:nonce”) ÷ 2^52, and each extra number adds “:1”, “:2” and so on to the message.
Before you bet
You see the SHA-256 hash of your server seed, which fixes it. Set your own client seed whenever you like.
Reveal the seed
Rotate your seed pair on the Fairness page. The old server seed is revealed and a new pair starts.
Recompute
Check that the seed hashes to what you saw, then paste it into the game’s verify panel, or any HMAC-SHA256 tool, to get the same result.
