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 rearranges when you bust. It does not move the 99% line. Table cap arrives before infinite recovery.
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.
Rolls are independent 0.00-99.99 values. Cold streaks at 90% win rate still happen over hundreds of rolls.
Sessions
How to run a Dice session
Pick one probability band for the session. The slider is honest: what you see is what you pay for.

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.
- Before the round, copy the server seed hash from the provably fair panel. That hash is the commitment. The raw seed is hidden until the round ends.
- Set or accept a client seed. The nonce increments on every bet. Together they feed the HMAC-SHA256 function Duel publishes in the rules.
- Play the round. When it settles, reveal the server seed and recompute the digest with your client seed and nonce.
- Map the digest to the game outcome using the rules for that title. If your result does not match what Duel paid, open a ticket with the round ID.

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.
Practical notes
If you understand Dice payout math, every other Original edge label makes sense.
Verification checklist
HMAC digest maps to 0.00-99.99. Published roll must match recomputation.
