Quick experiment · 30 seconds per run

Tap the glowing tile as fast as you can.

One tile lights up at a time. When it glows, tap it. Each correct tap is +1 point. You have 30 seconds per round. The goal isn’t stress — it’s a calm little focus exercise.

How it works:
  • Press Start run to begin.
  • Only tap the tile that’s glowing.
  • Round ends when the timer reaches zero.
Time: 30s
Score: 0
Best: 0

Ready. Press “Start run” when you want to focus for 30 seconds.

Reaction board

Tap only when the tile is glowing blue. Missed taps don’t penalize you; they just don’t add points.

Hint: Try a few slow runs first, then gradually speed up. This is a nice warm-up before studying.
