Frequently asked questions
What is the chimp test?
It is a working memory test based on a famous study where young chimpanzees beat humans at remembering the positions of numbers on a screen.
How does scoring work?
You start with 4 numbers and get one more each time you clear a level. A wrong click is a strike, and after 3 strikes your score is the most numbers you cleared.
What is a good chimp test score?
Most people reach 8–10 numbers. 12 or more is very good, and above 15 puts you near the top.
How can I get a better score?
Look at the whole grid before clicking 1 and group nearby numbers into small patterns. Remembering shapes works better than remembering each number alone.
