How to play Visual Search

Each field shows look-alike items with a single odd one out — a different shape or colour. Find it and tap it, and a denser field appears. A wrong tap costs a second. Catch as many as you can in 45 seconds.

What it measures

This is a visual search task, a workhorse of attention research. When the target pops out by one feature you find it instantly; when it differs by a combination you must scan — measuring how efficiently your attention sweeps a busy scene.

Honest note: This sharpens how quickly you find things in this kind of display. It's a fun attention workout — not a vision test or a diagnostic.

What's a good score?

Most players find 12–20 targets in 45 seconds; past 26 is quick eyes. The percentile we show is an estimate based on typical distributions, not a clinical norm.

FAQ

What makes the target different?

Either its shape or its colour differs from every other item in the field.
