How to Play Dice for Free
Win chance and payout update live as you drag the slider — the trade-off is the whole game.
If any game deserves to be your first, it is this free dice game. Crypto dice strips gambling down to its skeleton: pick a target with the slider, choose roll under or roll over, and bet. A number between 0.00 and 99.99 is drawn; if it lands on your side of the target, you are paid the multiplier shown before you rolled. There are no symbols, no near-misses, no music — just probability with a button on it.
Drag the slider and watch the two numbers trade against each other. Roll under 90 wins 90% of the time and pays a meagre 1.10×. Roll under 10 wins one time in ten and pays 9.90×. Every position multiplies out to the same expected return of 99%, which makes dice the one casino game where the house edge is not merely disclosed but displayed, live, before every single bet. Playing it with fake money for ten minutes teaches more about odds than most gambling guides manage in ten pages.
Dice is also where betting "systems" come to die, and you should bring one here for exactly that purpose. Try the Martingale — bet at 50, double after every loss — and watch how quickly the doubling ladder outruns a 10,000-credit balance. Try flat betting at 90% win chance and see the slow leak. Any progression you can invent rearranges the same −1% into a different shape: many small wins and rare disasters, or the reverse. The slider cannot be beaten; it can only be understood. Understanding it for free is the entire point of this page.
The Real Dice Maths
The payout is 99 / win chance, where the win chance in percent equals the target (rolling under) or 100 minus the target (rolling over):
| Bet | Win chance | Payout | Expected return |
|---|---|---|---|
| Under 98 | 98% | 1.0102× | 0.99 |
| Under 75 | 75% | 1.32× | 0.99 |
| Under 50 | 50% | 1.98× | 0.99 |
| Under 25 | 25% | 3.96× | 0.99 |
| Under 10 | 10% | 9.90× | 0.99 |
| Under 2 / Over 98 | 2% | 49.50× | 0.99 |
A fair game would pay 100/chance; the missing single point of the numerator is the house edge, applied identically at every slider position. Note that a 50/50 roll pays 1.98× rather than 2× — the same shave that a fair coin-flip should make famous.
Dice FAQ
Why does a 50% bet pay 1.98× and not 2×?
That 0.02 is the house edge made visible. Fair odds on a coin flip are 2×; paying 1.98× means the game keeps 1% of all money wagered over time. Every slider position is shaved by the same proportion.
Is roll over better than roll under?
No — they are mirror images. Over 40 and under 60 are the identical bet: 60% chance, 1.65× payout. The toggle exists for comfort, not for advantage.
Do betting systems like Martingale work on dice?
They change the shape of your results, not the sign. Doubling after losses produces many small winning sessions and occasional catastrophic ones; the long-run average stays −1% of turnover. Test any system here for free before believing it.
Are these the same odds as real crypto dice?
Yes — the 99/chance formula with a 1% edge is the industry standard used by Stake, Rainbet-style originals and virtually every provably-fair dice implementation.
