Why Dice

The cleanest odds slider in Originals

Dice shows you win chance and multiplier before every roll. No hidden pay table. No bonus stage. The 1% edge is the gap between fair odds and posted payout. That makes Dice the teaching tool of the catalogue: if you understand Dice, you understand how RTP works everywhere else.

Martingale on Dice survives until it does not. Table cap and bankroll limit arrive faster than most progression fans expect. The 99% RTP does not move because you doubled after a loss.
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.

Results are two-decimal rolls from 0.00 to 99.99. Each roll is independent. Cold streaks are variance, not memory.

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.

Pick one probability band for the session. Switching from 90% wins to 10% wins mid-session is just paying for excitement, not edge.
Provably fair

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.

What it is

Dice is Duel's over/under roll game. Players choose a threshold and direction, then receive a provably fair two-decimal result. It lives in Originals with a fully exposed probability model.

RTP and house edge

1% house edge at every target. Payout multiplier adjusts automatically so long-run return stays at 99%.

Bankroll and sessions

Low targets (90%+ win rate) suit flat small bets and long sessions. High targets (5% win rate) need deep bankroll and strict stop-loss. Auto-bet stop conditions are not optional on high-variance settings.

Vs other Originals

Versus Crash, Dice removes timing and shows exact odds upfront. Versus slots, Dice has no opaque feature buys.

VIP and promos

Counts toward VIP volume. No slot rakeback.
