Frequently asked questions
Why is it called the chimp test?
In a famous Kyoto University study, a chimpanzee named Ayumu recalled the positions of nine digits after seeing them for a fraction of a second, beating university students. This is the human-playable version of that task.
How does scoring work?
You start with four numbers. Complete a board and the next has one more. A wrong tap is a strike; three strikes ends the run, and your score is the largest board you completed.
What is a good score?
Most people manage boards of 7 to 9 numbers. Ayumu handled 9 reliably at a glance, which remains humbling.
