About this tool
Each die rolls independently using Math.random(), uniformly across every face — a d20 is exactly as likely to land on 1 as on 20. The history keeps your last 20 rolls so you can review a session without writing anything down.
Nothing rolled here is sent to a server — the entire tool runs as JavaScript in your browser tab.
