Dice Roller
Roll d4 to d100, several at once, with the totals worked out.
About the dice roller
Roll the standard polyhedral set — d4, d6, d8, d10, d12, d20 and d100 — one at a time or a fistful at once, with a modifier if your situation calls for one. Every roll shows the individual faces as well as the total, plus the minimum and maximum the roll could have produced, and the last few rolls stay on screen.
Results use the browser's cryptographic random source with unbiased range mapping, so each face is genuinely equally likely — which is more than can be said for most physical dice.
Reading dice notation
Tabletop games write rolls as NdX+M: roll N dice with
X sides each and add the modifier M. So
2d6+3 means roll two six-sided dice and add three, giving a result between 5
and 15.
Worth knowing: multiple dice do not produce a flat distribution. One d20 is equally likely to give any number from 1 to 20, but 3d6 clusters hard around 10 and 11 — you will roll a 10 about 12.5% of the time and a 3 about 0.5%. That is why damage rolls using several small dice feel much more predictable than a single large one.
Frequently asked questions
What does 2d6 mean?
Roll two six-sided dice and add them together, giving a result from 2 to 12. The notation is NdX — N dice with X sides — and a trailing +M or −M is a modifier applied to the total.
Is an online dice roller fair?
This one is arguably fairer than a physical die. It draws from your browser's cryptographic random source and maps values onto the range without bias, whereas real dice have manufacturing tolerances that make some faces marginally more likely.
How do I roll a d100?
Select d100 from the die buttons. It produces a number from 1 to 100 directly, which is equivalent to the traditional percentile roll of two ten-sided dice.
Can I roll several dice at once with a modifier?
Yes. Set the die type, how many, and the modifier. The result shows each individual face, the total after the modifier, and the possible range.
