RACE START

Test your reaction time on a real racing start sequence. Hold the clutch, wait for the lights, and launch the instant green flashes.

How it works

Three steps between you and your true reaction time.

1

Hold the clutch

Press and hold CLUTCH to arm the start. Releasing early is a fault, just like a real launch.

2

Wait for the lights

Red, yellow, then green after a random delay. You can't anticipate it, only react.

3

Launch on green

Hit GAS the instant green flashes. Your reaction time is measured to the millisecond.

Features

A pure reaction challenge with nothing in the way.

Millisecond timing

Precise launch measurement from green light to gas input.

Random start delay

Every run is different. No memorizing, only reflexes.

Jump start detection

Gas before green or early clutch release and it's a fault.

Best time tracking

Chase your personal record and sharpen your launch.

Start light sounds

Audio cues on every light, just like the real gantry.

Dark racing theme

Clean, focused design that keeps your eyes on the lights.

In action

The grid, and a 255 ms launch.
