Provably Fair Verifier - Verify Dice & Limbo Rolls Yourself
Paste the seeds from a completed betting session and recompute the results. If they match what the casino paid, the games were fair - math, not trust.

Which algorithm does my casino use?
HMAC-SHA256 (Stake, Rollbit, Shuffle-style): result float = first 4 bytes of HMAC(serverSeed, clientSeed:nonce:0) / 256^4, roll = floor(float x 10001) / 100 for dice (0.00-100.00). SHA256-concat: the classic crypto-dice scheme - take SHA256(server+client+nonce) as hex, use the first 8 hex chars / 0xFFFFFFFF as a float, multiply by the modulo (10001 = standard 0.00-100.00 dice roll). If your site documents its scheme, match it here; if the numbers reproduce, the operator could not have altered outcomes. Read the full walkthrough in the provably fair guide →
