Roll the dice
Roll d4 to d100 online — up to 20 dice at once, with modifiers and totals.
Runs locally in your browser. Nothing you roll is ever sent to a server.
Press "Roll" to throw the dice.
Sides
Press Roll and the dice come up, with each die shown separately and the total underneath. Choose the number of sides, how many dice to roll and an optional modifier, and you have a replacement for a physical set that fits in a pocket.
The buttons cover d4, d6, d8, d10, d12, d20 and d100 — the set used by most tabletop role-playing games. Six-sided is the default because it suits board games and everyday decisions, but a d20 is a press away when it is needed for an ability check.
Roll up to 20 dice at once and the total appears with the individual faces below it, so you can see what made up the number rather than trusting a single figure. The modifier is added to the total after the roll, which is what notation like 2d6+3 means: roll two six-sided dice, add three to the sum.
A physical die can be chipped, loaded or thrown badly. A digital roll has the opposite risk: a weak random source that quietly favours some faces. This roller draws from your browser's cryptographic random source and discards values that would fall outside a clean multiple of the number of faces, which is the step that removes that bias entirely.
Each die is rolled independently using your browser's cryptographic random source, with rejection sampling so every face is equally likely. Rolling many dice does not change that: the total naturally clusters in the middle because there are more ways to make a middling sum, which is a property of the dice rather than a bias in the generator.
Press Roll and the dice come up. Choose how many sides and how many dice first — six-sided is the default.
Yes. The side buttons cover d4, d6, d8, d10, d12, d20 and d100, which is the full set used in most tabletop games.
Yes. Roll up to 20 dice in one press. The total is shown underneath along with each individual result.
Yes. Set a modifier and it is added to the total, so 2d6+3 works exactly as it does at the table.
Yes. Each die is rolled with your browser's cryptographic random source using rejection sampling, so every face has an equal chance.
Yes. The page is built for mobile, so it works as a dice replacement when you have a game but no dice.
