Dice Roller
The Dice Roller rolls any number of virtual dice (d4, d6, d8, d10, d12, d20, or d100) with a cryptographically-fair result and a running total. Perfect for board games, tabletop RPGs like D&D, and the classroom when you don’t have physical dice handy.
Roll up to 20 dice (d4, d6, d8, d10, d12, d20, or d100) at once. Every roll is cryptographically fair — a true, unbiased result — perfect for board games, tabletop RPGs, and classroom use. Runs entirely in your browser.
How This Tool Works
Pick your die type (d4 through d100) and how many to roll, then press Roll. Each die shows its value and, when you roll more than one, the total is added up for you.
Formula & Method
Each die uses your browser’s cryptographically-secure random generator with rejection sampling, giving every face an exactly equal probability — a true, unbiased roll.
Example Calculation
Playing D&D and need to roll two d20 with advantage? Select d20, set the count to 2, and roll — you’ll see both values and their sum instantly.
