Chimp Test: Can You Beat a Chimpanzee's Memory?

About this test

Numbers starting from 1 appear scattered across a grid of 40 squares. Memorize where they are, then tap 1: every other number turns into a blank white tile, and you must tap the hidden tiles in order, 2, 3, 4 and so on. You start with 4 numbers and get one more after each success. A mistake costs one of your three lives and gives you a fresh layout with the same count. When all three lives are gone, your score is the most numbers you cleared. The test comes from a 2007 study by Sana Inoue and Tetsuro Matsuzawa at Kyoto University's Primate Research Institute. A young chimpanzee named Ayumu remembered the positions of numbers flashed on a screen and touched them in order, and when the numbers were shown only briefly, he was more accurate than university students. It is a fun way to glimpse how much of a scene you can capture at a single glance.
