About this tool

Built for D&D and tabletop role-playing, the dice roller rolls the classic d20 — and the rest of the polyhedral set (d4, d6, d8, d10, d12, d100) — and adds your modifier to the total. Handy for attack rolls, skill checks and saving throws when your physical dice are out of reach.

How to use it

  1. Choose a die (d20 by default) and how many to roll.
  2. Set a + or − modifier if your check needs one.
  3. Tap Roll to see each die and the modified total.
  4. Roll again for the next check.

Frequently asked questions

Which dice can I roll?
The full polyhedral RPG set — d4, d6, d8, d10, d12, d20 and d100 — one or many at a time, exactly like a physical dice set for D&D or Pathfinder.
Does it add my modifier?
Yes. Set any positive or negative modifier and it's added to the dice total automatically.
Can I roll with advantage or disadvantage?
Yes — roll two d20 at once, then take the higher result for advantage or the lower for disadvantage.
Is the result truly random?
Yes. Every outcome uses your browser's cryptographically secure randomness, so it is unbiased and unpredictable — just for fun.
Can I roll multiple dice?
Yes — roll up to ten of the selected die at once, with the modifier applied to the sum.
