# Dice Roller — Roll Virtual Dice Online

Roll one or many dice — d4, d6, d8, d10, d12, d20, d100 — with fair, unbiased results. 100% in your browser — free, no sign-up.

## What the dice roller does

It rolls virtual dice: pick a die size — the classic six-sided d6 or the tabletop set d4, d8, d10, d12, d20, and d100 — choose how many to roll (up to 20), and get each result plus the total. Recent rolls stay listed so you can look back.

## Are the rolls fair?

Yes. Each die uses your browser's cryptographically secure randomness with rejection sampling, so every face has an exactly equal chance — no modulo bias, no weighting. Each roll is independent: past results never change the odds of the next one.

## When to use it

Board games when the dice have gone missing, tabletop RPGs like D&D (d20 for checks, d4–d12 for damage), classroom probability demos, or any random pick from 1 to N — a d100 is a quick percent roll.

## Dice notation

Tabletop games write rolls as NdS: 2d6 means roll two six-sided dice and add them. Set the die to d6 and the count to 2 to match. Flat modifiers like +3 are just added to the total afterwards.

## How to

1. Choose the die size (d4 to d100) and how many dice.
2. Click Roll the dice.
3. Read each die and the total — recent rolls stay in the history.
