Roll Dice Online — Any Number, Any Sides
Roll virtual dice: d4, d6, d8, d10, d12, d20, or custom. Perfect for board games, D&D, and tabletop RPGs.
Dice Notation Explained
Tabletop RPGs use XdY+Z notation: X dice with Y sides plus Z modifier. 2d6 = roll two six-sided dice. 1d20+5 = roll one twenty-sided die, add 5. 3d8-2 = roll three eight-sided dice, subtract 2. The d20 is the iconic die in Dungeons & Dragons, used for attack rolls, ability checks, and saving throws. A natural 20 is a critical hit; a natural 1 is a critical failure.
Probability Distributions
A single die gives a uniform distribution — each face equally likely. Multiple dice create a bell curve centered on the average. 2d6 averages 7, with 7 being the most common result (6 ways to roll it out of 36 possible combinations). Rolling 12 or 2 has only a 1/36 (2.8%) chance. This is why Catan uses 2d6 — resources on 6 and 8 produce more often than those on 2 and 12.
