How to play Focus

Find the signal. Ignore the distraction.

Thirty signals arrive at a steady pace. Respond only to the green arrow. Start with circles; red arrows, squares and diamonds join after ten decisions. After twenty, blue and purple arrows and more shapes join, including green stars. Both quick responses and correct restraint matter.

1. 01

   Click, tap, or press Space only when the green arrow appears.

2. 02

   Let every other signal pass, including arrows in other colors and green shapes. Red arrows join after 10 decisions; blue and purple arrows and more shapes join after 20. The response window stays the same.

3. 03

   The score is correct decisions out of 30. Reaction time and false alarms are shown separately.

Each signal has a color-and-shape label so the rule does not depend on color perception alone. A missed green arrow or response to any other signal counts as one incorrect decision.
