In Dungeons & Dragons it covers dagger and magic-missile damage, and it is a favourite for teaching basic probability because every outcome is easy to enumerate by hand. This page preloads a single D4 so you can roll a fair, unbiased value between 1 and 4 instantly — no signup, no app, straight in your browser.
