Roll ordinary six-sided dice or simulate non-conventional dice with any number of faces. Every result is generated on your device and includes the individual rolls, sum, and product.
Examples
Two six-sided dice
Possible sums run from 2 through 12. Seven is the most common because six different pairs produce it.
Three d20 dice
Choose 20 sides and 3 dice. Results range from 3 to 60, and each individual die has a 5% chance of showing any particular face.
Formula
For an
s-sided die, each result is a uniformly selected integer from 1 through s. For n fair dice, the expected sum is n × (s + 1) / 2.Use the conventional roller for board games and the custom roller for tabletop role-playing dice such as d4, d8, d10, d12, and d20.
Randomness limits
The interactive roller uses the browser's cryptographic random-number generator (Web Crypto). It is suitable for casual games and classroom simulations, but it is not auditable physical randomness and must not be used for cryptography, regulated drawings, gambling systems, or decisions requiring a verifiable random process. Each die is modeled as independent and fair; real dice may not be.
