A straight-to-the-point response speed measurement game with vibrant visual panel, random delay, false start penalty, and local stats.

Compare several attempts because one result can vary with attention and timing.
Clicking before the signal creates a penalty; wait for green so the attempt counts.
Sleep, distraction, screen, and device can change the milliseconds—use the game as a reference, not a diagnosis.
The test is for people who want to measure and train their reflexes, compare results with friends, or warm up before playing.
After the round starts, the green signal appears after a random wait between 1.6 and 4.2 seconds, so the moment cannot be guessed.
Measured from the green signal to your click.
