Roll the dice
Choose how many dice to roll and how many sides each has, then roll. The tool shows each die and the total, with an optional bonus or penalty. It suits board games, tabletop role-playing and quick decisions.
How it works
- Pick the number of dice and the sides.
- Add a bonus if needed.
- Press Roll and read each die and the total.
Dice notation
The label 2d6+3 means roll two six-sided dice and add 3. The tool shows this label above each result so the roll is easy to read back.
Fair dice
Every face has the same chance, because each die is picked with your browser's secure random numbers. There is no bias toward low or high numbers.
Common dice
A d6 is the standard board-game die, d20 is used in many role-playing games, and a d100 gives a percentage.
Roll history
Your last few rolls are listed under the result so you can compare them. The history clears when you reload the page.
