Verify a roll
Every open is provably fair. Paste the receipt below and recompute the result yourself; it runs entirely in your browser.
How it works
Before each spin we commit to a hashed server seed. Your client seed and a nonce (a counter that increments every open) are mixed in, and the outcome is HMAC-SHA256(serverSeed, clientSeed:nonce) and the first 32 bits become a number in [0, 1) that lands on the weighted drop table. When you rotate seeds we reveal the server seed, so you can confirm the hash you saw upfront and reproduce the exact item. Recompute it here, or with any HMAC tool, and it will agree.
