What is the Dice Roller?

The Dice Roller is a virtual dice tool for board games, tabletop RPGs, classroom activities, and quick decisions. Choose how many dice and how many sides, roll, and get a fair, instant result — no physical dice needed and nothing to lose under the couch.

How it works

Each roll of a die with s sides is generated as Math.floor(Math.random() × s) + 1, giving a whole number from 1 to s with equal probability. Rolling several dice simply repeats this and sums the results. Because each roll is independent, past results never influence the next one.

Example 1: Rolling 2d6 (two six-sided dice) can total anywhere from 2 to 12, with 7 the most likely sum because more combinations add up to it.
Example 2: A single d20 returns a number from 1 to 20 — the classic attack or skill check in tabletop role-playing games.

When to use it

Play a board game when the real dice have gone missing. Run combat or skill checks in Dungeons & Dragons and other RPGs. Pick a random winner or make a fair decision. Or use it in class to teach probability with live, repeatable rolls.
