Dice Roller
Built for tabletop nights where the dice are in the other bag. Pick the die size, how many, and any modifier; you get every individual result plus the total, so nothing is taken on trust.
Fill in the form, then run it.
This tool needs JavaScript. Nothing you enter is ever uploaded.
How to use the dice roller
- Choose the die type and how many to roll.
- Add a modifier (like +3) to apply it to the total.
- Every die is rolled independently with the browser's cryptographic random source.
Dice Roller questions
Which dice are supported?
d4, d6, d8, d10, d12, d20 and d100 — up to twenty dice in a single roll.
Are the rolls actually uniform?
Yes. The roller uses rejection sampling on the cryptographic random source, which avoids the slight bias a naive modulo would introduce on die sizes that don't divide evenly.
Can I see each die, not just the total?
Yes — individual results are listed alongside the total, so a critical hit is never hidden inside a sum.
