What This Trains
Stimulus recognition, click timing, decision speed, and recovery after missed or early reactions.
Match the color displayed. 20 continuous rounds — no pauses. Build a streak for bonus points!
20 continuous rounds of color matching. The target box shows a color — click the matching button as fast as possible. Correct answers in a row build a streak multiplier. No pauses between rounds — stay sharp!
Try the Stroop Effect Test for a harder color-based cognitive challenge, or the Visual Reflex Test for pure reaction time measurement.
Stimulus recognition, click timing, decision speed, and recovery after missed or early reactions.
Take several attempts instead of trusting one result. Reaction time varies with sleep, caffeine, hardware latency, and focus.
