Is this dice roller fair?

Yes. Each roll comes from the secure random number generator built into your browser, the one it also uses for encryption (Web Crypto), not from a predictable formula. A random number that would make one face slightly more likely is thrown away and drawn again, so on a d6 every face comes up exactly 1 time in 6 in the long run. The roll happens on your device and is sent nowhere.

Fair does not mean even in the short run. Ten rolls of a d6 can easily show three 5s and no 2 at all. That is what real dice do too.

Which dice for which game

• d6: the classic die with pips, for most board games, Yahtzee, ludo and dice drinking games. Most games roll 1 or 2 of them.
• d4, d8, d10 and d12: role-playing games such as Dungeons & Dragons, for weapon damage and spells.
• d20: the main die of Dungeons & Dragons, rolled for attacks and checks.

Two dice: why 7 comes up most

With 2 dice there are 36 equally likely pairs, and 6 of them add up to 7, more than any other total. A 2 or a 12 needs one exact pair each, so they turn up least. Our dice probability calculator works out the chance of any total for any dice.
