Green Light

A quick go / no-go game. Tap on green, hold on red, and see how steady you stay under time pressure.

How it works
  • 1Tap the green dot the instant it lands. Speed counts.
  • 2When the red stop appears, hold still. Do not tap.
  • 3Miss a green and the run ends. Tap three reds and it ends too.

Green Light leans on response inhibition: going fast on green while holding still on red. It is a game, not a measure of anything about you.

Works with sound off. Your device, caffeine, and focus all move the number.
