Lights Out
Five red lights. They hold. Then they vanish — go.
How to play
- 1
Five lights come on one by one. Do not move.
- 2
They hold for an unpredictable moment, then all go out at once.
- 3
Tap the instant they vanish. Five rounds, averaged. Jumping the start costs you.
Why it works
This is the starting procedure used in motorsport, and it is harder than reacting to something appearing: you are reacting to something stopping. The hold is deliberately unpredictable so you cannot time it — anticipate and you jump, wait passively and you are late.
FAQ
What counts as a good time?
Around 250–300ms is typical on a touchscreen. Under 240ms is sharp; professional racing drivers land near 200ms on purpose-built hardware.
Why is my phone score worse than on a computer?
Touchscreens add their own delay before your tap is registered. Compare phone runs with phone runs.
