Dice Roller

Scan to open this page

Free online dice roller — roll any number of dice with any number of sides (not just standard d4/d6/d20), with a running roll history and no ads.

How it works

  1. Set the number of dice and sides per die (or tap a common preset like d6 or d20)
  2. Tap Roll
  3. See the total, each individual roll, and a history of your last 10 rolls

Frequently asked questions

Can I roll non-standard dice, like 1-3 or 1-5?

Yes — sides can be any number from 2 up to 1000, not just physically real dice shapes. Some dice roller apps only allow standard die sizes; this one doesn't.

Is the randomness fair?

Yes — it uses your browser's cryptographically secure random number generator (crypto.getRandomValues) with rejection sampling to avoid modulo bias, so every side has an exactly equal chance.

A d4, d6, d8, d12, and d20 exist as physical objects. A d3 or a d15 doesn't — but plenty of games and decisions still need one. Most dice roller sites simply refuse.
