Dice Roller
Roll one or more dice with custom sides and see the results.
What is Dice Roller?
A dice roller simulates throwing one or more dice with a chosen number of sides, from classic 6-sided dice to tabletop favourite d4, d8, d10, d12, and d20.
Each die value is drawn independently and uniformly from 1 to the number of sides, so every outcome on a single die is equally likely. The tool sums the values to give the total of the roll.
How does the Dice Roller work?
Individual outcomes are flat — a d6 rolls 1 through 6 with equal probability — but totals follow a bell-shaped distribution because there are more combinations summing to the middle values.
For example, with 2d6 there are 36 equally likely outcomes, and a total of 7 is the most common because six combinations produce it.

Frequently Asked Questions
Are the dice rolls random?
Yes, each value is picked uniformly from 1 to the number of sides, and every roll is independent of previous ones — no results are weighted or reused.
What is the most likely total in the game?
For a single die every face is equally likely. With multiple dice, middle totals are most probable; with 2d6 the total of 7 appears most often (6 of 36 outcomes).
Can I use it for games besides D&D?
Yes. Select however many dice your game calls for and the matching side count, including d4, d8, d10, d12, and d20, for any tabletop system.
Whatever you are working on, the Dice Roller is the quick way to double-check a figure before you rely on it.
