🧠 Chimpanzee Memory Test: The Ayumu Experiment

Numbers appear scattered across the screen for a heartbeat. Tap 1 and the rest go blank instantly, leaving you to hit the remaining positions from memory alone. Each round adds one more number and you get three lives. The task comes from the Kyoto University work with the chimpanzee Ayumu, who could hold a whole layout after a single glance — a snapshot ability most adult humans traded away long ago.
