D20 Roller

Summary

Roll any RPG die (d4 through d100) with a custom quantity and modifier — see each result and the running history log.

How it works

1. Select a die type by clicking one of the die buttons (d4, d6, d8, d10, d12, d20, or d100).
2. Enter the number of dice to roll in the Quantity field (1 to 20).
3. Optionally enter a modifier — a positive or negative integer added to the total.
4. Click Roll or press Enter to roll and see individual die results and the grand total.
5. Consecutive rolls are logged in the History panel at the bottom for easy reference.
6. Click Clear History to wipe the log and start fresh.

Use cases
