Traffic Light
The light stays red for a stretch nobody can predict. When the green comes on, click — every millisecond counts. There are five starts per race, and clicking early jumps the start.
Engine cold.
Press “New race” to light up the signal.
Getting started
- Light up the signal. The button starts the race and the red comes on right away.
- Wait for green. The wait is random on every start: from one to three and a half seconds.
- Click the track. The big area next to the light is your pedal; click it the moment the green comes on.
- Don't jump. Clicking on red turns on the yellow and the start begins again.
- Finish all five. The average of your five reactions is your final time.
Starting tips
- Look at the bottom lamp, not the cursor: the cue reaches you through your eye first.
- Keep your finger resting on the mouse or the screen; reaching in to press costs tens of milliseconds.
- Breathe between starts. Nerves shorten your patience, and that's what jumps starts.

Yes, with touch. A touchscreen usually responds a little differently from a mouse, so compare best scores made on the same kind of device.
Reaction time is sensitive to fatigue, distraction, and even the time of day. Playing a few races in a row warms up your reflexes; the difference between the first and third race is usually noticeable.
