Click Roll dice or press the space bar. Six-sided dice show real pips and other dice show their number.

Dice Probability Basics
- Each face of a fair D6 has a 1 in 6 chance, about 16.7%.
- With two D6, 7 is the most common total (6 out of 36 combinations) and 2 and 12 are the rarest (1 in 36).
- A natural 20 on a D20 happens 5% of the time.
- Past rolls do not change future rolls. A die has no memory.
Dice Roller Tips
- Share your screen on video calls so other players can see each roll.
- Use the history to settle arguments about what was rolled.
- For advantage in D&D, roll 2d20 and use the higher number, shown in the Highest card.
