Reflex
Reaction Time
A test of raw reflex speed. Wait, watch, tap — measured in milliseconds. Repeated 5 times to give you a fair average.
How to play
Screen stays gray — wait
The screen is gray. A random delay passes — could be 1 second, could be nearly 4.
Green — tap immediately
The moment it turns green, tap anywhere on the screen (or press Space).
