Reaction Test

📖 How to Play & Objective

Measure your reflex speed in milliseconds. Wait through the suspenseful red screen until it suddenly turns bright green, then click as fast as humanly possible!

• Click once to begin the test sequence.
• Wait patiently while the screen is red. Clicking prematurely counts as a false start.
• The moment the screen turns green and displays "CLICK!", click immediately.
• Your reaction time is measured in milliseconds and logged to your best scores.

💡 Tips & Strategy

• Focus your vision slightly unfocused on the center to detect color change faster than processing shapes.
• Keep your finger hovering just above the key or screen with slight tension.
• Average human reaction time is 200–250ms — can you break into the sub-180ms range?
