Roll dice online
Pick a die and how many, then roll. Every face is equally likely and the total is added up for you.

Die
Each die is rolled independently with the browser's cryptographic random source, so the faces come up evenly.

How it works
Each die is rolled independently
Not one number split up. Rolling 3d6 draws three separate values, which is what gives the total its characteristic bell curve — a single draw from 3 to 18 would be flat and quite different to play with.
Even faces, no modulo bias
A d6 from a random 32-bit value using the modulo operator is very slightly biased toward the low faces. Values in the biased tail are discarded and redrawn, so all six faces are exactly equally likely.
What it does
Seven dice types
d4, d6, d8, d10, d12, d20 and d100.
Up to twenty at once
With every individual roll shown, not just the total.

No account and no upload — what you type is never sent anywhere. Analytics records that the tool was opened, never what you put into it.
Practical advice
Getting a better result
- The individual rolls are shown as well as the total, because most tabletop rules care about the individual numbers.
- 3d6 is not the same as 1d18 — the three dice cluster around 10 or 11, while a single die would be flat.
Questions
Things people ask
Are the dice fair?
Yes, and more so than physical dice — there is no weighting, no wear and no edge bias. Each face has exactly the same probability, verified by rejecting the values that would otherwise skew the distribution.
