Dice Roller
Roll any number of dice with any number of sides, with modifiers and standard RPG notation.
Formula
standard notation: 2d6+3 means two six-sided dice plus three
Tips
- Standard notation is NdS+M: 3d6+2 rolls three six-sided dice and adds two.
- Dropping the lowest die is the usual method for rolling character statistics — it shifts the distribution upward.
- Rolls use the cryptographic random source, so they are not predictable from previous results.
Frequently asked questions
Why do multiple dice cluster around the middle?
Because sums of dice follow a bell-shaped distribution. On 2d6 there is one way to make 2 but six ways to make 7, so 7 comes up six times as often.
