About this tool
Roll dice using standard NdM notation such as 2d6+3 directly in your browser, with each result generated from crypto.getRandomValues.
Frequently asked questions
What notation is supported?
Standard NdM±K, for example 2d6, d20 or 3d8-1, where N is the number of dice, M the sides and ±K an optional modifier.
How are the rolls generated?
Each die uses the browser's cryptographically secure random generator with rejection sampling, so every face is equally likely.
