About Reaction: Four-Mode Reflex Speed Trainer

Reaction is a reflex-speed trainer built around four quick challenge modes — Sweep, Ring, Traffic Light, and Ball — packed into one compact test. The goal is simple each time: tap at the exact right moment, and every precise hit shrinks the target and raises the difficulty. Adjustable difficulty, dark and light themes, and global best-score tracking round out the experience, making it easy to jump in and immediately chase a better result.

How to Play Reaction

Each of the four modes asks for one well-timed tap. Miss the green zone and the challenge stays forgiving; nail it and the target shrinks, pushing your precision further.

The Four Reflex Tests

• Bar: tap when the marker hits the green zone
• Ring: tap when the needle crosses the green sector
• Traffic Light: tap when green turns on
• Ball: tap the ball the moment it turns green

Controls

• Tap / Click: register your reaction on screen
• Space or Enter: register your reaction on keyboard
• Esc: quit
