D&D Dice Roller — Roll All RPG Dice from d4 to d100
D&D Dice Roller simulates all Dungeons & Dragons RPG dice types: d4, d6, d8, d10, d12, d20, and d100. Roll multiple dice at once and calculate totals or check individual results.
The tool also supports dice notation like 2d6+3 (two six-sided dice + 3 bonus) and saves recently used rolls for quick repetition. Perfect for all D&D, Pathfinder, and other d20-based role-playing games.
What is the d20 used for in D&D?
The d20 is Dungeons & Dragons' most important die — used for attack rolls, saving throws, and ability checks. A natural 20 is a critical hit or perfect success, while a natural 1 is a critical failure. Dice d4-d12 are primarily used for calculating damage based on weapon or spell type.

- Roll d4, d6, d8, d10, d12, and d20 dice – also d100.
- Roll multiple dice at once and see individual results plus the sum.
- You can add bonus or penalty modifiers to the roll.
Each roll is random and independent of previous rolls.
- A d20 roll is the most common skill check in D&D – add your skill bonus to it.
- Advantage/Disadvantage: roll two d20s and use the higher or lower result.
- Damage dice results (e.g., 2d6+3) are calculated as a sum plus bonuses.
The dice roller uses the browser's random number generator, which is sufficiently random for role-playing use.
- Results are pseudo-random – fair enough for game nights.
- The roller doesn't replace the atmosphere of physical dice but is a handy backup system.
- History can be tracked during play – useful in dispute situations.
