Choose whether to bet "Roll Over" or "Roll Under" your target number.
- 3
The multiplier adjusts automatically — lower win chance means higher payout.

Click Roll. A provably fair random number between 0 and 99.99 is generated.
- 5
If the number beats your target in your chosen direction, you win bet × multiplier.
Provably Fair System
The dice roll is a single float derived from HMAC-SHA256(server_seed, client_seed:nonce). The first 4 bytes of the hash are converted to a uint32, then divided by 2^32 to produce a float in [0, 1). This is scaled to 0–99.99 and compared to your target.
Visit the Fairness Verification page to verify any past round with your seeds.
