Roll a d20 online

Attack rolls, ability checks, saving throws: tabletop role-playing games lean on the twenty-sided die, the d20, and one is ready to roll here. Tap it, press Roll or hit the Space bar. Each number from 1 to 20 has a 1 in 20 chance, or 5%, on every roll.

The d20 in role-playing games

In Dungeons & Dragons and many games inspired by it, the d20 decides whether an action works: you roll, add your bonus and try to reach a target number. On an attack roll, a natural 20 (a 20 on the die itself) is a critical hit, and a natural 1 always misses. Each has a 5% chance.

Roll on the die	Chance
20 (natural 20)	5%
1 (natural 1)	5%
15 or higher	30%
11 or higher	50%
At least one 20 with advantage (2 dice)	9.75%

To roll with advantage or disadvantage, tap “one die” and choose 2 dice: keep the higher roll for advantage, the lower one for disadvantage. The average roll of a d20 is 10.5.
