How Dice works
You pick a direction (over or under) and a target between 1 and 99. The platform rolls a number between 0.00 and 99.99 using the provably fair hash. If the result satisfies your condition (under your target or over it, depending on direction), you win at the multiplier shown. If not, you lose the stake.
The multiplier is calculated from the win chance using a fixed formula: multiplier = 99 / win chance. Win at 50% chance pays 1.98x. Win at 25% chance pays 3.96x. Win at 1% chance pays 99x. The 99 in the numerator is where the 1% house edge lives.
The full multiplier table
Every setup carries the same -1% house edge. There is no win-chance value that is mathematically better. What changes is variance and hit frequency.
| Win chance | Multiplier | Implied ROI per roll |
|---|---|---|
| 98% | 1.01x | -1% |
| 75% | 1.32x | -1% |
| 50% | 1.98x | -1% |
| 33% | 3.00x | -1% |
| 25% | 3.96x | -1% |
| 10% | 9.9x | -1% |
| 5% | 19.8x | -1% |
| 2% | 49.5x | -1% |
| 1% | 99x | -1% |
Strategy: high-chance vs low-chance
- High win chance (75% to 98%): tiny multipliers, very smooth ROI curve. Best for clearing wagering with the least variance.
- Mid win chance (25% to 50%): moderate variance. Good for casual play with the occasional swing.
- Low win chance (1% to 10%): lottery-style. Most rolls lose. The wins pay big enough to recover, but session-to-session variance is huge.
- Martingale on 50%: doubles after every loss, targets 1.98x. Statistically tempting. Practically dangerous: a 10-loss streak (which happens roughly once per 1,000 sessions) wipes the bankroll.
- Anti-martingale on 50%: doubles after every win, resets on loss. Same long-run EV, but the downside on a cold streak is the original bet only.
Pros and cons of Dice
What we like
- Simplest casino game in the entire catalogue
- 99% RTP across every win-chance setting
- Provably fair, every roll verifiable
- Fast: 2 seconds per roll manually, 10+ rolls per second on auto-bet
- Auto-bet supports martingale, anti-martingale, custom step logic
What we don't
- Zero skill ceiling: you cannot beat the 1% edge with any strategy
- Visually plain compared to Crash or Plinko
- Low-variance setups feel like a slow drip
- High-variance setups burn bankrolls fast
How to set up auto-bet on Dice
-
1
Open Dice from Originals
Loads in ~2 seconds.
-
2
Set win chance to 50%, direction 'roll under 50.50'
Multiplier shows 1.98x.
-
3
Set bet to 0.5% of bankroll
On $1,000, that is $5 per roll.
-
4
Choose strategy: on-loss increase 0%, on-win increase 0%
Flat staking, no martingale. Lowest variance auto-bet setup.
-
5
Set stop-loss at 30%, stop-win at 30%, run 500 rolls
Expected outcome: roughly break-even with ~1% drift down. Variance is gentle, wagering clears reliably.
The math behind '99 / win chance'
The formula is a deliberately simple way to encode the 1% house edge. A fair game would pay 100 / win chance (50% win chance, 2.00x payout). The casino takes 1 off the numerator. That is the entire mathematical trick. There is no hidden complication, no rake on top, no obscure side rule. It is provably and verifiably a 99% RTP.
Some players try to find inefficiencies. For example, switching between 50% and 25% rounds depending on the last result. Mathematically, this changes nothing. Each roll is independent. The expected return is -1% per roll, no matter the order.
