Visual memory test

Memorize the briefly highlighted tiles in a 5x5 grid, then tap them back - order does not matter. Each round adds one more tile.

Memorize the highlighted tiles

Some tiles of a 5x5 grid light up briefly - tap exactly those tiles afterwards, order does not matter. Each correct round adds one more tile.

In 3 steps

  1. Click "Start test".
  2. Watch which tiles of the grid briefly light up.
  3. Tap exactly those tiles back (order does not matter); a mistake shows you the tile count you reached.

Visual memory tests your spatial short-term memory: some tiles of a 5x5 grid light up briefly, then you tap exactly those tiles again - order does not matter. Every fully correct round adds one more tile, until you tap one wrong tile - the tool then shows you the largest tile count you recalled correctly. The highlighted tiles are chosen with the browser cryptographic random source. Everything runs locally: no account, no server, no transmission of your results.

What counts as a normal value? Standardized spatial short-term memory instruments (such as block-tapping procedures from neuropsychology) are clinical test tools, not openly published datasets that could be cited here - so this tool deliberately shows no computed comparison value, only the tile count you reached.

Distraction and practice noticeably affect your result. Your best score, history and streak are stored locally in your browser - with a visible export and delete button, so your data genuinely belongs to you.

Limitations: Measures short-term retention of an unordered tile selection via tapping - not an IQ test and not a medical or psychological diagnosis. There is no published comparison study for this test that we know of, so the tool deliberately shows no computed comparison value.

FAQ

Are my results uploaded or stored?

Nothing is uploaded: the measurement runs entirely locally in your browser. Your best score, history (at most the last 50 runs) and streak are stored locally - you can export them as a JSON file or delete them with one click at any time. There is no account and no server leaderboard.

What is a good visual-memory result?

There is no openly published comparison study for this browser test that we know of, so the tool deliberately shows no computed percentage. The most meaningful comparison is against yourself over several runs.

Can I train my visual memory?

To some extent, yes: regular practice and strategies like recognizing spatial patterns (for example corners or lines) demonstrably help. The underlying memory capacity itself cannot be increased indefinitely though.

Is this an IQ test?

No. Visual memory is a memory benchmark for spatial short-term memory, not an IQ test and not a psychological or medical diagnosis.
