FATE // LAB · D20 ROLLER
D20 Roller
This page opens FATE with a D20 ready to roll. Add a modifier, or choose advantage or disadvantage: FATE rolls two physical D20s and uses the higher or lower actual settled face. The animation does not hide a separate generated result.
One-tap D20 setup
The D20 preset configures one 20-sided die and modifier zero. It never rolls automatically; you decide when fate gets involved.
History you can repeat
Each completed roll can retain its setup, so Repeat generates fresh randomness with the same configuration.
More than D20
Switch to the full dice roller whenever you need D4 through D100 or mixed polyhedral pools.
FATE // LAB is a browser-based randomness tool. Results are for games, everyday decisions and entertainment — not for gambling, security keys or other high-stakes uses.
