About this game

Inspired by the chimp Ayumu (Kyoto Primate Institute), this game shows digits 1-N briefly on a 5Γ—4 grid. Once they hide, you must click them back in ascending order β€” pure spatial-numeric working memory.

Adults often max out at 7-8 digits at this flash speed. Ayumu the chimp consistently exceeded human performance at higher speeds.
