In 2007, Kyoto University researchers tested a young chimpanzee named Ayumu against university students. Numbers 1–9 flashed on a screen in random positions, then turned into blank squares. The task: tap them in ascending order from memory.
Ayumu did it after seeing the numbers for just 210 milliseconds — faster than an eye blink — at roughly 80% accuracy. Adult humans dropped to about 40% at that speed.
To play: the numbers are already on the board. Study them. Tap Start — they vanish and the clock runs. Tap them in order, lowest to highest. One wrong tap ends the round.
Normal is the real experiment: 9 numbers, same as Ayumu faced. SuperChimp is 20 numbers, well beyond anything tested on a chimp or a human in the original study. Best times are tracked separately for each mode.
The only thing that counts is your time. Miss a tile and the run is over with no time recorded — you have to get every number for it to count. The clock starts the instant you tap Start and stops on your final correct tap.
There's no invented 1–100 rating here. Just the clock, and whether you beat your own best.
PERFECT!
