Dice for every game

d6: board games, Yahtzee-style games, classroom maths.
d4, d8, d10, d12, d20: tabletop role-playing games.
d100: percentile rolls, 1 to 100.

Every die is rolled separately and shown on its own, with the total underneath.

Fair rolls

Each die is a whole number drawn with rejection sampling from your browser’s cryptographic random generator, so every face has exactly the same chance. The fairness page shows the same picking code run a million times.

Why two dice give 7 most often

With two six-sided dice there are 36 combinations, and six of them add up to 7, more than any other total. That is why 2 and 12 are rare. If you need every total from 2 to 12 to be equally likely instead, use the number wheel with that range.

Questions

Are online dice random?

These use your browser’s cryptographic random generator, the one used for security, so the rolls cannot be predicted.
