About the test

How quickly can you react? Watch the screen, and the moment it turns green, tap. The colour changes at a random moment, so you cannot guess the timing.

Tap too early and the round starts again. After five rounds you see your average time, your best round and how it compares with your previous best.

How it works

  1. Watch the screen and wait. Do not tap yet.
  2. The moment it turns green, tap as fast as you can.
  3. Tap too early and that round restarts.
  4. After five rounds, see your average, your best round and your previous best.
