How it works
A custom dice roll takes two choices: how many dice and how many sides. The page opens on two six-sided dice, so the first press already rolls. For another size, type its highest number, or tap d20 once the first roll is down.

Set up your own dice
A size name counts the sides: a d6 is the common cube and a d20 has twenty faces. After the first roll, tap d20, d12 or d10 to change every die at once; d8, d6, d4 and d100 are under More options. For an unusual die, such as 30 sides, type 30 as Highest. How many takes any count up to 100. Values 1 to 6 are drawn as pips; larger dice show numbers.
Dice rolling for an RPG night
A role-playing set has a d4, d6, d8, d12, d20 and two d10s, and every one is a tap here. Set the size and the count once; each press then rolls the whole handful.
Tips
- To roll 30 dice at once, set How many to 30. The faces wrap onto several rows.
- Roll the dice, win a prize: at a party, number six small prizes 1 to 6 and let each guest roll one die for theirs.
- On a real six-sided die the opposite faces add up to seven: 1 and 6, 2 and 5, 3 and 4.
Questions and answers
What does d100 mean?
A roll from 1 to 100. At the table it is usually made with two ten-sided dice, one read as the tens and one as the ones. Here it is a single draw from 1 to 100.
Which total comes up most with two dice?
7. Six of the 36 ordered rolls make it, a chance of 1 in 6. The table under the tool lists every total from 2 to 12 with the rolls that make it, and doubles.
Is this dice roller fair?
Yes. Each die is a separate draw made in your browser, every face with the same chance. There is no AI and no memory of the last roll. It is meant for games, lessons and fair turns.
