About this game

Feel the adrenaline of a Formula 1 start right on your smartphone!

Do you have what it takes to react like a world-class racing driver? Lights Out is the ultimate reaction time tester designed to simulate the high-pressure start of a Grand Prix.

How to Play:
Get Ready: Tap the screen to begin the sequence.

Focus: Watch the five red lights turn on one by one.

The Wait: Once all lights are lit, stay focused! They will go out at a random interval (between 1 to 4 seconds).

GO: The moment the lights vanish, tap the screen as fast as you can!

Key Features:
Precision Timing: High-fidelity measurement using professional-grade frame timing.

F1 Experience: Authentic light sequence and immersive sound effects (beep!).

Jump Start Detection: Just like in a real race, if you react too early, you fail! No cheating allowed.

Personal Best: Save your high scores locally and challenge yourself to shave off every millisecond.

Minimalist Design: Clean, dark-themed UI that keeps your focus where it belongs—on the lights.

Whether you're a die-hard F1 fan or just someone who wants to test their brain-to-finger speed, Lights Out offers a quick, addictive, and competitive experience.
