Chimp Test

Chimp Test Rules

The Chimp Test measures your visuospatial working memory — your ability to remember the locations of numbers after briefly seeing them. It was made famous by a study at the Primate Research Institute of Kyoto University , which found that chimpanzees can outperform humans on this task.

In this test, a set of numbers will appear on the screen in random positions. After you click on number 1 , the numbers will be hidden, leaving only blank squares in their place. Your task is to click the squares in ascending numerical order (1, 2, 3, and so on) based on where you remember each number was located.

Each successfully completed level increases the total number of numbers to remember, making the challenge progressively harder. An incorrect attempt earns you a strike.

Begin the level by clicking on number 1.
