Roll any combination of polyhedral dice in one click. This free online dice roller handles d4, d6, d8, d10, d12, d20, and percentile dice, with advantage and disadvantage, bonuses and penalties, critical hits, and a running history, for D&D 5E, Daring & Dread, and any other tabletop RPG.
How to use the dice roller
- Click a die to add it to the roll. Click again for more, or right-click to take one away.
- Use the plus and minus buttons for your bonus or penalty, such as +5 to hit.
- Choose Advantage or Disadvantage for d20 rolls.
- Add a label like Longsword attack so your history makes sense later, then press Roll or hit Enter.
Dice notation
You can also type a roll directly. The roller understands standard RPG dice notation:
- 2d6+3: two six-sided dice plus three
- d20-1: one twenty-sided die minus one
- 4d6kh3: roll four d6 and keep the highest three (or 4d6dl1, drop the lowest one)
- 2d20kl1: roll two d20 and keep the lowest
- d% or d100: percentile dice
- 1d8+2d6+4: mix as many dice as you need
Saved rolls and history
Save the rolls you make every session, like your attack, your damage, or a favorite spell, and roll them again with a single click. The history keeps your last 25 rolls, and it flags every natural 20 and natural 1.

Frequently asked questions
Is this dice roller really random?
Yes. Every roll uses your browser's cryptographic random number generator, the same kind of randomness used for security, and each die is perfectly even. In a test of 200,000 d20 rolls, every face came up about 5% of the time.
How do I roll with advantage or disadvantage?
Pick Advantage or Disadvantage, then roll. Each d20 is rolled twice and the higher (or lower) result is kept. Both dice are shown, with the one that doesn't count faded out.
Can I roll ability scores?
Yes. Use the Ability scores saved roll, or type 4d6kh3 to roll four six-sided dice and keep the highest three.
How do critical hits work?
Check Critical hit to double every die in the roll, then add your bonus once, which is how critical damage works in 5E and Daring & Dread.
Does it save my rolls?
Your saved rolls and roll history are kept in your own browser on this device. Nothing is sent anywhere.
Does it work on a phone?
Yes. It's built to work at the table on a phone, tablet, or computer.
