Every roll is floor(mulberry32(fnv1a(serverSeed:clientSeed:nonce)) × 10000) / 100 — a uniform number from 00.00 to 99.99, locked to a seed committed before you rolled. Payout is always 99 ÷ win-chance, so RTP is exactly 99% at every slider position.

? HOW TO PLAY
Drag the stone handle or edit any box — multiplier, target and win chance stay linked. ROLL OVER t wins when the roll lands on t or higher; tap the middle box to flip to ROLL UNDER t (wins strictly below). Win chance runs 2–96%, payout = 99 ÷ chance — up to ×49.5.
Type bets like 2.5M, 250K or 500.000.000. AUTO opens the autobet drawer: roll count (0 = forever), and on win / loss either RESET the bet or raise it by a % (+100% on loss = martingale). Stops on Stop, count out, or bet outgrowing balance.
SPACE roll · ←/→ move target · U flip over/under · M mute · RTP exactly 99% everywhere.
