How virtual dice work
Each die is rolled separately: the tool picks a whole number from 1 to the number of sides, with every face equally likely. The results are listed in order and summed. Two six-sided dice (written 2d6) can total anything from 2 to 12, but 7 comes up most often because six of the 36 combinations add to 7.
Once you are done here, the coin flip tool picks up where this leaves off.
How to use it
Set Number of dice and Sides per die, then press Roll. Tabletop players can use 4, 6, 8, 10, 12 or 20 sides; board gamers usually want 2d6. Each roll is independent of the last. For a single value in an arbitrary range, the random number generator is simpler.
A worked example: 3d6 can total anything from 3 to 18, but 10 and 11 come up far more often than 3 or 18, which is why so many role-playing systems use it for ability scores.
Groups often move straight on to the random list picker afterwards.
Randomness and security
Every result on this page is produced in your own browser with JavaScript's built-in Math.random() pseudo-random generator. That is perfectly fine for games, giveaways, classroom picks and decision-making, but it is not cryptographically secure — never use it to generate keys, tokens or anything protecting real money or private data. Nothing you type is uploaded; the page never sends your inputs anywhere.

Frequently asked questions
- How many dice can I roll at once?
- Up to 100. Every die is listed individually and the total is shown above the list.
- Can I roll a d20?
- Yes. Set sides per die to 20, or any other value from 2 upwards, for D&D-style rolls.
- Are the dice fair?
- Yes — each face has an equal chance. Streaks of the same number are normal and appear in physical dice too.
- What is the range of 2d6?
- Between 2 and 12. The most common total is 7, and 2 or 12 each turn up about once every 36 rolls.
- Can I roll unusual dice such as a d3 or d100?
- Yes. Any side count from 2 upwards works, so d3, d7 and d100 are all fine even where no physical die exists. A percentile roll is simply one d100.
