Dice Roller
Set how many sides each die has and how many dice to roll, then tap Roll. Results show individual values and a total when you roll more than one die.
Dice Roller
How it works
Each die roll uses random bytes mapped into the range 1 … sides. Odd-sided dice get as fair a mapping as the remainder allows; for critical play use physical dice.
Use this tool for
- RPG sessions when you forgot your dice bag.
- Quick classroom probability demos.
- Generating random integers within a fixed modulus (e.g. D20).
Common questions
What should I double-check before trusting Dice Roller?
Sides per die and number of dice must be positive integers within the form limits.
Why does my answer differ slightly from another site?
Different apps use different RNGs; for cryptographic fairness use dedicated hardware, not a browser dice demo.
