D&D Dice Roller

A fast, free online dice roller built for Dungeons & Dragons — roll a d20, roll with advantage or disadvantage, roll ability scores, or use custom dice notation.

Pick a die or enter notation to roll.

Every roll your D&D game needs

Lost your dice, playing online, or just want a quick roll? This free D&D dice roller covers the full polyhedral set — d4, d6, d8, d10, d12, d20, and d100 — plus the rolls that actually come up in play: advantage and disadvantage on a d20, and 4d6-drop-lowest ability scores for new characters.

Need a specific roll? Type dice notation like 2d6+3 for damage or 8d6 for a fireball, and the roller shows every die plus the total. When you're ready to take the dice to a real table, find a campaign on the iRolled20 game finder or a shop on the store locator.

How do I roll with advantage or disadvantage?
Use the advantage and disadvantage buttons. Advantage rolls two d20s and keeps the higher result; disadvantage rolls two d20s and keeps the lower one — exactly as in D&D 5e. The breakdown shows both dice so you can see what was rolled.
Can it roll D&D ability scores?
Yes. The "Roll ability scores" button rolls 4d6 and drops the lowest die, six times — the standard method for generating a new character's ability scores. Each line shows the three dice that were kept.
Does it support custom dice notation?
Enter notation like 2d6+3, 1d8, or 3d10-1 in the custom roll field and press Roll. It works for any combination of dice and modifiers, so you can roll damage, healing, or anything your spell or weapon calls for.
