About Green Light
A reaction test with a real scoreboard. Five lights at random intervals; jump the gun and the round is void. Your average in milliseconds is the score everyone compares.
- How to play: tap the panel or press Space to start.
- A go takes about 20 seconds. The daily puzzle is identical for every player and resets at your local midnight.
- Share any score as a challenge link — whoever opens it faces the same puzzle with your number to beat.
