Roll 1 to 100 • Choose your own odds • Play money only • Not affiliated with Rainbet
Each roll is a random whole number from 1 to 100. You slide a target and choose under or over. If the roll lands on the right side, you win your bet times the payout. The smaller your win chance, the bigger the payout.
It is the simplest game on the site, and a good place to see how risk and reward trade off. All credits are play money.
The payout is 99 divided by your win chance in percent. That means every setting returns 99% of what you stake on average. Safer settings pay less and riskier ones pay more, but the long-run return is the same.
| Win chance | Payout | Setting (roll 1 to 100) |
|---|---|---|
| 1% | 99× | under 2 / over 99 |
| 5% | 19.8× | under 6 / over 95 |
| 10% | 9.9× | under 11 / over 90 |
| 25% | 3.96× | under 26 / over 75 |
| 49% | 2.02× | under 50 / over 51 |
| 50% | 1.98× | under 51 / over 50 |
| 75% | 1.32× | under 76 / over 25 |
| 90% | 1.1× | under 91 / over 10 |
| 98% | 1.01× | under 99 / over 2 |
A target of 50 under needs a roll of 49 or lower, which is a 49% chance, so it pays a little over 2×. Roll over works the same way from the other end of the scale.
Thinking about doubling after losses? Our Martingale guide runs that exact plan for you.
Yes. It uses play money only and you can roll as many times as you like.
None is better in the long run. Every setting returns about 99% on average. Lower win chances only give bigger swings.
