How to use Reaction Time Test
Press Start Round, keep your finger or mouse ready, and wait until the panel turns green. Tap too early and the round is cancelled. Tap after the signal to record your reaction time and compare it with your best score.
For best results, play one round at a time and use the restart button when you want a clean score. The game is lightweight, but your reaction, focus, and accuracy can change from round to round, so repeat attempts are part of the fun.
