Welcome to Reflex Redline

Reflex Redline is a reaction time game that recreates the Formula 1 start light experience. Test your reflexes by reacting when the lights go out, just like F1 drivers at the start of a race.

How to Play

1. Hold the button at the bottom of the screen.
2. Watch the five red lights count down (one per second).
3. After the fifth light, wait for all lights to turn off.
4. Release the button as soon as the lights go out.
5. Your reaction time is measured and displayed.

Tip: Don't release too early. Wait until all lights are off, or you'll get an error message.

Features

• F1 start light experience — Authentic countdown sequence
