Visual Memory Test

How to take the visual memory test

1. Press Start. Three tiles on a 3x3 grid light up for about a second.
2. When they go dark, click the tiles that were lit, in any order. A correct tile turns green; a wrong one turns red.
3. Find every lit tile to finish the level. The next level adds one tile, and the grid grows by one row and column every two levels.
4. Three wrong clicks in a single level cost a life and the pattern is shown again before the level restarts. You have three lives.
5. When the lives are gone, the level you reached is your score. Your best level is kept in this browser.

What the results mean

Your score is the level at which the game ended, which is also the number of tiles you were trying to remember plus two. It measures visuospatial short-term memory: how many positions you can hold after a brief look.

The pattern is shown for one second plus a little extra per tile, so the test is about capacity, not speed. If you lose lives on levels you normally pass, you are probably tired or distracted; the score varies more with attention than most people expect.

How visual memory works

Visual short-term memory is limited to roughly four objects at a time when the objects are unrelated. People manage many more tiles on this test because the brain does not store the tiles one by one; it stores the shape they make. A diagonal line of five tiles is one object. An L, a cross, a pair of parallel bars, a near-square: each is a single chunk, and the capacity limit applies to chunks. That is why the best strategy is to look at the whole pattern and name its shapes rather than counting tiles.

This kind of task is close to the Corsi block test and the visual patterns test used in neuropsychology, which assess the visuospatial sketchpad of working memory. Those are administered under controlled conditions and scored against age norms; this page is a game for curiosity and self-tracking, not an assessment.

Tips for a higher score

Fix your eyes on the centre of the grid and take in the whole pattern at once; scanning tile by tile loses the edges. Describe the pattern to yourself in shapes ("a diagonal from the top left, and a pair in the bottom right"). Click the tiles you are sure of first; the ones you are unsure of often come back once the shape is partly rebuilt on screen. Avoid guessing when you are down to one or two uncertain tiles, since three misses cost a life; a slower careful click is cheaper than a quick wrong one. For a version that tests order as well as position, try the sequence memory test, and for numbers on a grid the chimp test.

Common problems and fixes

The tiles light up too briefly

The display lasts one second plus 0.12 seconds per tile, which is the same for everyone. Focus on the centre of the grid before the pattern appears so you see all of it.

Nothing happens when I click

Clicks are ignored while the pattern is shown and during the short pause between levels. Wait until the tiles go dark.

I clicked a correct tile and it turned red

Each tile only counts once. If a tile is already green and you click it again, nothing happens; red always means the tile was not part of the pattern.

The grid is cramped on a phone

Later levels use up to a 10x10 grid. Landscape orientation keeps the tiles large enough to tap accurately.
