Apeproval

Apeproval is a memory game based on a chimpanzee experiment from Kyoto University. Numbers appear on the screen for a brief moment, then get covered up. You tap them in order from lowest to highest, going by memory alone.

It starts easy. Three or four numbers is manageable. By six or seven it gets hard. Eight or nine is really hard. Anything beyond that is exceptional.

The game is inspired by research on the working memory of chimpanzees, who can do this kind of task faster and more accurately than most humans. Whether that's true photographic memory is debated, but the result is the same: you'll probably lose to a chimp.
