A challenging visual short-term memory test inspired by the research where chimpanzees outperformed humans in memory tasks.

This web-based memory test challenges your visual short-term memory across three difficulty levels. The game is based on cognitive research that demonstrated chimpanzees' superior ability to recall sequences of numbers compared to humans.
