⚡ THE CORE GAME LOOP
1. Tap the screen to enter the Waiting state.
2. Watch the row of professional circular traffic lights illuminate one by one.
3. The instant the lights fire the GO signal—TAP!
4. Measure your reaction time in high-precision milliseconds and unlock your professional rank!
Warning: Tap too early and you’ll trigger a False Start!

🎯 3 DYNAMIC TRAINING MODES
• Visual Focus (Classic F1): Watch the classic zinc-housed red start lights. Train your visual processing and muscle readiness.
• No-Go Inhibition (Cognitive Control): The ultimate mental agility test. If the final lights turn BLUE instead of green, do not tap! Tapping early or on a No-Go signal resets your streak.
• Audio Response (Low-Latency Sound): Close your eyes and react purely to sound frequencies. A low beep prepares you, and a high-frequency square wave triggers the GO command.
