Questions and answers
How is the 1xDICE result generated?
HMAC-SHA256 of the server seed with your client seed and bet number gives a number between 0 and 1. It is multiplied by 100 and rounded down, giving 00–99.
How do I verify a roll?
Change your seed pair to reveal the old server seed, then enter it with the client seed and nonce in the Verify tab. The calculation runs in your browser.
