Dice roller: d4, d6, d8, d10, d12 and d20
Dice from d4 to d20, with the total, breakdown and range, up to 100 at once.
Why different dice
d4, d6, d8, d10, d12 and d20 are the standard set for tabletop role-playing games. The notation "3d8" means three eight-sided dice: values from 1 to 8 on each. The calculator understands this notation and shows not only the total but the individual faces — handy when every roll matters, not just the sum.
Total and range
For a batch we show the possible range: 2d6 gives 2 to 12, 3d8 gives 3 to 24. An important detail: the total is not uniformly distributed. On two d6 a seven comes up more often than a two or a twelve, because more combinations lead to seven. If you need uniformity, take a single die or a number generator.
How many dice to roll
Up to 100 at a time — enough for a tabletop game and for testing house rules. For larger simulations the random number generator is a better fit: it handles batches of up to 1000 values and statistics on them.
The generator uses a cryptographic source of randomness, so rolls do not depend on the time of launch and do not repeat a pattern.
Frequently asked questions
What does d20 mean?
A die with 20 sides: a value from 1 to 20 inclusive, each equally likely. The notation comes from tabletop role-playing games.
Are the dice summed?
Yes, for a batch we show the total and the possible range: 2d6 gives 2 to 12, for example, and 3d8 gives 3 to 24.
How many dice can I roll?
Up to 100 at a time. That is more than enough for a tabletop game; for simulations, use the number generator with a larger count.
