How it works
Roll one or more dice with the browser's cryptographic random source: every face has exactly the same chance, and nothing can be predicted from previous rolls.
- Choose how many dice to roll.
- Roll, and read the faces and the total.
- Roll again as often as you like — each roll is independent.
Dice have no memory. After four sixes in a row, the next roll is still one in six — the feeling that a number is “due” is the gambler's fallacy.
Examples
The odds worth knowing, for two dice:
| Total | Ways to make it | Chance |
|---|---|---|
| 2 or 12 | 1 | 2.8% |
| 3 or 11 | 2 | 5.6% |
| 4 or 10 | 3 | 8.3% |
| 5 or 9 | 4 | 11.1% |
| 6 or 8 | 5 | 13.9% |
| 7 | 6 | 16.7% |
Seven comes up most often because there are more ways to make it. For dice with other numbers of faces, use the dice roller.
Dice: frequently asked questions
- What is the probability of rolling a six?
- 1 in 6, or about 16.7%, on every roll: previous rolls don't change the odds.
- Can I use this for board games?
- Yes. It works like a physical die and is handy when dice go missing.
- Is this dice roller really random?
Yes. Each roll uses the browser's cryptographic random source, the same one used for security keys, so no sequence can be predicted or reproduced.
- What is the most likely total with two dice?
Seven, at about 16.7%. There are six ways to make it, against one way each for 2 and 12.
- Can I roll more than two dice?
Yes — choose the number of dice before rolling, and the total is added up for you.
