About the d20

Roll a d20 dice with 20 sides. We let you roll any number of dice, like 2 D20s or 10 D20s. Add any number and roll with all history needed, showing the last 10 dice rolled and the sum of each roll.

Mostly Dungeons & Dragons and other RPG games use it, for attack rolls, saving throws and skill checks. Some board games too.

Questions about the d20

What is the chance to roll a 20?

5%, so one time from twenty. Rolling a 1 has the same chance.

How do I roll with advantage?

Turn on the advantage button, or write 2d20kh1 in the notation box. Two dice are rolled and we keep the bigger one. Disadvantage keeps the smaller.

Is an online d20 really random?

Yes. We use the random generator of your browser, so every side has the same chance. And a plastic dice is not always balanced.
