Dice

Predict whether the next roll will land over or under a target you choose. Payout is proportional to the probability — bet on a 5% chance and win 19.8×, bet on a 95% chance and win 1.04×. 99% RTP across every target. Variance entirely up to you.

How to play

How Dice works

Slide the target between 0.01 and 99.99. Pick over or under. The probability of winning equals the slider position; the payout multiplier is 99 / probability (the 1% gap is the house edge). Roll. The result is a number 0.00–99.99; if it falls on the predicted side, multiplier × stake pays out.

Strategy

Target selection and bankroll math

All target selections share the same 99% RTP — pick what matches your variance tolerance, not what feels lucky. 95%-win/1.04× is a smooth grind; 50%-win/1.98× is balanced; 5%-win/19.8× is high-variance hunting. Martingale on Dice is a classic bankroll killer: doubling after each loss only works until you hit the table cap or your wallet limit, both of which arrive faster than people expect.

How to verify a Dice roll

Each roll is derived from HMAC-SHA-256 of the seed pair + nonce; the first 4 bytes are mapped to a number in [0, 99.9999]. Recompute the digest, apply the same modulo, get the same roll the casino published.

FAQ

Dice FAQ

Why is the max payout 9,900× and not 100×?

At 0.01% win chance, payout is 99 / 0.0001 = 990,000× theoretical, capped at 9,900× by table policy. The cap is published in the rules and reflected in the displayed multiplier.

Does Martingale work on Dice?

No. It survives long losing streaks until it doesn't — at which point you hit the table cap or your bankroll. Long-run EV is unchanged at 99%.

Are 'cold streaks' real?

Each roll is independent. Streaks happen because of variance, not because of memory. Past results don't change the next roll's probability.

Can I auto-bet Dice with stop-loss?

Yes. Auto mode supports number of rolls, target/over-under settings, increase-on-win, increase-on-loss, stop-on-profit and stop-on-loss conditions.
