Why a 3D die instead of a number
A printed number tells you the outcome; a rolling die makes the outcome feel earned. That matters when several people share a screen — at a table, in a classroom, or on a video call. Everyone watches the same throw, so nobody has to trust anyone else's roll.
Dice types and what they are used for
- D4 — small damage rolls and quick four-way choices.
- D6 — the classic cube for board games and family games.
- D8 and D10 — weapon damage and percentile-style systems.
- D12 — months, hours, or heavier RPG weapons.
- D20 — checks, saves and attacks in tabletop role-playing.
- D100 — loot and event tables that need percentages.
- Custom sides — anything from 2 to 1000 for homebrew rules and teaching probability.
Rolling several dice
Choose up to six dice and each one is rolled independently, with the sum shown underneath. That covers 2d6 for board games, 4d6 for character creation, and 3d8 for damage without any mental arithmetic.
Teaching probability with it
Roll 2d6 twenty times and record the totals: seven appears most often because six of the thirty-six combinations add up to it. The recent-rolls list keeps your last twelve throws so a class can build the distribution together.
