About Nat20 Roller

Nat20 Roller is a small set of free dice tools for tabletop players and game masters. It started from a simple want: a dice roller that loads fast on a phone at the table, reads real dice notation and does not get in the way.

How it works

Every roll happens in your browser using the Web Crypto random number generator, with rejection sampling so no face is favored. There are no accounts. Roll history and saved rolls stay in your browser's local storage.

Rules and trademarks

The tools are built for 5e play and cite rules from the System Reference Document 5.1, which Wizards of the Coast publishes under the Creative Commons Attribution 4.0 license. Nat20 Roller is independent and is not affiliated with, endorsed or sponsored by Wizards of the Coast.
