About this tool
How it works.
For the table that forgot the dice bag. All 20 faces are evenly weighted, and every roll carries a verifiable receipt, which is more accountability than any physical d20 has offered a suspicious dungeon master. Put it on a shared screen and the whole party watches the same roll happen.
Everything is editable. Replace the list with your own, weight an entry by adding x3 after it, or switch draw modes above the entry box. Nothing is saved to a server, so your list stays in this browser.
What people use it for
- Rolling initiative without dice
- Settling a skill check
- Playing D&D over video call
Tip
Share the link so every player rolls the same die, then point at the Receipt tab when someone claims the critical hit was made up.
