Numbers appear in a grid. Click the first number and the rest turn into blank squares. Now click the squares in order from memory. Each round adds one number. Three strikes and the run is over.

The test is based on experiments in which young chimpanzees outperformed adult humans at remembering the positions of briefly shown numbers. It measures short-term visual memory, not intelligence, so do not take a bad score personally. You start with 4 numbers on a 6 x 5 grid. When you finish a round the next one has one more number. A wrong click is a strike and replays the same count with a new layout. Your best score is saved in this browser only.
| Numbers remembered | Rating |
|---|---|
| 4 - 6 | Below average |
| 7 - 9 | Average |
| 10 - 14 | Above average |
| 15 or more | Exceptional |
These bands are rough guides, not a clinical test.
It is a short-term visual memory game inspired by research on chimpanzees, which can memorize the positions of numbers on a screen very quickly. You click the squares in numerical order after the numbers disappear.
Most adults reach 7 to 9 numbers. Reaching 10 or more is a strong result. The test starts at 4 numbers and adds one each round.
Clicking a wrong square costs one strike and restarts that round with a new layout. After three strikes the run ends.
