Dice Roller
Roll virtual dice — choose how many dice and how many sides. Change either option to roll again.
Common dice roller uses
Beyond tabletop games, virtual dice rollers are useful for random decision-making, classroom probability demonstrations, and quick random number generation within a specific range without needing physical dice on hand.
For tabletop role-playing games, non-standard dice like d20 (20-sided) or d4 (4-sided) are common — simply set the sides field to match whatever die type your game calls for.
A worked example
Rolling 2 six-sided dice (2d6, common in many board games): possible totals range from 2 to 12, with 7 being the statistically most common result since it has the most possible combinations (1+6, 2+5, 3+4, and their reverses).
Rolling a single d20 (common in tabletop RPGs) gives an equal 1-in-20 chance for each result from 1 to 20 — no single number is more likely than any other, unlike the bell-curve distribution of multiple dice summed together.
Common dice notation in games
Tabletop games often use shorthand like '2d6' to mean 'roll two six-sided dice,' or '1d20' for a single twenty-sided die roll — this calculator's number-of-dice and sides fields let you replicate any standard dice notation directly.
Different die types serve different purposes in game design — d20 is common for skill checks and combat rolls in many role-playing games, while d6 remains the most familiar die from traditional board games and gambling.
Frequently asked questions
Can I roll non-standard dice, like d20?
Yes — set the sides field to any number, such as 20 for a d20 or 4 for a d4, commonly used in tabletop games.
Is this suitable for tabletop RPG games?
Yes — set the sides field to match your game's dice notation (like 20 for a d20), and roll multiple dice at once by adjusting the number of dice field.
How random are the rolls?
Rolls use your browser's cryptographically secure random number generator, providing high-quality randomness suitable for games and other everyday random selection needs.
What does '2d6' mean in tabletop games?
It means 'roll two six-sided dice and sum the results' — standard shorthand notation used across many tabletop and role-playing games.
