How it works
Pick a die type (d4, d6, d8, d10, d12, d20 or d100), choose how many dice to roll from 1 to 20, then press Roll. Choosing d6 shows the classic pip faces (⚀–⚅); other dice display their numeric value. The combined total appears in large type below, so you can quickly resolve damage rolls, ability checks, or any sum-based mechanic in games like D&D.
Fair, random results
Rolls are generated using the browser's cryptographic random source (crypto.getRandomValues), which is more unpredictable and evenly distributed than basic pseudo-random methods. The totals of your last 10 rolls are listed under Recent totals, so you can track a streak across a session. It's handy for game night, classroom activities, or decision games when you'd rather not carry physical dice.
Frequently asked questions
How many dice can I roll at once?
You can roll between 1 and 20 dice in a single throw. Each die is rolled independently and the tool shows the sum of all of them as one result.
How does the d100 work?
The d100 produces a single number from 1 to 100. Instead of pip faces it shows the numeric outcome, which suits games that call for percentile checks.
