⚡ Reaction Time Arcade

About this game

Reaction Time is a minimalist test of pure human reflex, stripped down to the simplest possible interaction so that nothing at all stands between you and an honest measurement of how quickly your brain can respond to a visual cue. You click a large box to begin, and it immediately turns red while you wait for a randomized delay of one to roughly three and a half seconds, deliberately unpredictable so you cannot simply anticipate the exact timing and click too early. The instant the box flips to green, your job is to click it again as fast as humanly possible, and the game measures the gap in milliseconds between the color change and your click, displaying the precise result immediately afterward. Click too soon, before the box has actually turned green, and the round is voided as a false start, teaching real self-control alongside raw speed. Your best-ever reaction time is saved locally so you always have a personal record to chase, and comparing your results against typical human reaction benchmarks, which usually sit somewhere in the two to three hundred millisecond range, adds a fun extra layer of context to every attempt.
