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.
