Dice probability in a nutshell
With one die, every face is equally likely: 1 in 6 for a d6, 1 in 20 for a d20. With two or more dice, middle totals become more common because there are more ways to make them. Two d6 can make 7 in six ways (1+6, 2+5, 3+4, 4+3, 5+2, 6+1) but 2 in only one way (1+1). That is why 7 is the most common roll in games like Catan and Craps, and why the average of many dice clusters around the middle.
Dice in the classroom
- Addition and multiplication practice: roll two dice and add or multiply the faces.
- Probability experiments: roll 100 times and compare the results with the expected 1 in 6.
- Random selection: number your groups and roll to choose who presents. For bigger groups, use the name picker.

Frequently asked questions
Is the online dice roller fair?
Yes. Each die uses your browser’s cryptographically secure random number generator with rejection sampling, so every face has exactly the same chance — often fairer than cheap physical dice, which can be slightly unbalanced.
What do d4, d6 and d20 mean?
The number after "d" is the number of faces. A d6 is a normal six-sided die, a d20 has twenty faces and is used in Dungeons & Dragons, and a d4 is a four-sided pyramid.
Can I roll several dice at once?
Yes, up to 10 dice of the same type. The total is added up for you, and the last 20 rolls are listed in the history.
What is the most common total with two dice?
7. There are 6 ways to make 7 out of 36 combinations, so it comes up about 16.7% of the time. 2 and 12 are the rarest, at 1 in 36 each.
Can I roll with the keyboard?
Yes — press Space or R anywhere on the page to roll.
