Online Dice Roller

Roll any dice — D4 to D100 — with modifiers and totals.

Added to the total, not to each die.

Overrides the fields above.

Roll type
Values come from the browser cryptographic generator using rejection sampling, so every face is exactly as likely as every other — unlike a plain remainder, which would favour the low numbers slightly.

What does Dice Roller do?

Roll one die or a whole handful. It covers the standard polyhedral set from D4 to D100, accepts dice notation such as 2d6+3, and shows each individual die alongside the total, which is what tabletop games actually need. Randomness comes from the browser cryptographic generator.

How to Use Dice Roller

  1. 1
    Pick your diceChoose a die type and how many, or type dice notation.
  2. 2
    Add a modifierOptional, and applied to the total rather than each die.
  3. 3
    RollEvery die is shown individually, with the total below.

Key Features

  • Every standard polyhedral die: D4, D6, D8, D10, D12, D20 and D100
  • Dice notation support, so 3d8+2 rolls exactly that
  • Individual die results shown next to the total
  • Advantage and disadvantage rolls for D20 systems
  • Roll history, so a disputed roll can be checked
  • Cryptographic randomness with no modulo bias

Frequently Asked Questions

What does 2d6+3 mean?

Roll two six-sided dice, add them together, then add three to the total. It is the standard notation used by tabletop role-playing games, and you can type it directly into this roller.

Are the rolls genuinely fair?

Yes. Values come from the Web Crypto generator and are drawn with rejection sampling rather than a plain modulo, which is what stops the lowest few numbers appearing slightly more often than the rest.

How does a D100 work?

It produces a number from 1 to 100. At a physical table it is usually rolled as two ten-sided dice — one for tens, one for units — but the outcome is identical to the single result shown here.

What are advantage and disadvantage rolls?

A D20 mechanic where you roll twice and keep the higher result for advantage, or the lower for disadvantage. Both rolls are shown here so you can see what was discarded.
