How to roll dice online
- Choose how many dice to roll (1–10).
- Pick the dice type: d6 for board games, or d4, d8, d10, d12, d20 and d100 for tabletop RPGs.
- Tap the dice, press Roll, or hit Space. The total is added up automatically.
Dice for every game
- Board games: Monopoly, Yahtzee, Ludo, Backgammon and Snakes & Ladders use d6.
- Dungeons & Dragons: d20 for attacks and checks, d4 to d12 for damage, d100 for percentiles.
- Maths class: explore probability by rolling 2d6 and charting how 7 comes up most.
- Drinking and party games: assign a challenge to each number.
- Decisions: give each option a number from 1 to 6 and roll.
Are virtual dice fair?
Yes, and often fairer than real ones. Cheap physical dice can be slightly unbalanced by drilled pips or uneven edges. Our dice roller uses a cryptographically secure random number generator, so every face has exactly the same chance on every roll.
Dice notation explained
| Notation | Meaning |
|---|---|
| d6 | One six-sided die |
| 2d6 | Two six-sided dice, added together |
| d20 | One twenty-sided die |
| 3d8 | Three eight-sided dice, added together |
| d100 | A percentile roll from 1 to 100 |
| 2d6+3 | Two six-sided dice plus 3 |
The number before the d is how many dice to roll and the number after it is how many sides each has. Set both above and the total is worked out for you; add any bonus yourself.
Odds with two dice
With two six-sided dice the totals are not equally likely, because there are more ways to make the middle numbers.
| Total | Chance |
|---|---|
| 2 or 12 | 2.78% each |
| 3 or 11 | 5.56% each |
| 4 or 10 | 8.33% each |
| 5 or 9 | 11.11% each |
| 6 or 8 | 13.89% each |
| 7 | 16.67% |

- Beat That: roll three dice and arrange them into the biggest number you can, so 2, 5 and 3 become 532. Highest number takes the round.
- Roll and add: for young children, roll two dice and add them up. First to reach 50 wins.
- Odds and evens: one player is odd, the other even. Roll one die ten times and score a point for every match.
See the odds for your dice
Below the dice is a chart of the exact chance of every total for the dice you have selected. One die gives a flat line, because every face is equally likely. Two dice give a triangle that peaks at 7 for 2d6. Add more dice and the shape rounds into the familiar bell curve.
Your own rolls are drawn as bars over those lines, so you can watch real results gather around the theory. Press Roll 1,000 times or Roll 100,000 times to run a batch instantly: after a few thousand rolls the bars sit almost exactly on the lines. The chart also shows the most likely total, the expected average and your actual average. For the reasoning behind the shapes, read dice probability explained.
