Chimp Memory

Can you beat a chimpanzee? Memorize the sequence of numbers on the grid. The moment you click the first tile, the rest disappear.

Kyoto University Primate Research

This exact test was administered to chimpanzees (notably Ayumu) at the Primate Research Institute. While young chimps can flash-memorize 9 numbers instantly, adult humans average less than 6. Can you outsmart genetics?

As you advance, the number sequence continually grows. Successfully pushing past Level 10 proves your eidetic (photographic) trace memory sits within the highest percentiles of visual capacity globally.
