This is a website created to represent a visual representation of a memory test created by Tetsuro Matsuzawa to train chimpanzees memory ability. Chimpanzees can do this test within 0.5 seconds to memorize the numbers. You can watch the free episode of Mind Field talking about this on youtube. And yes it's possible to cheat this game but why would you do that, to prove to your friends that you are better than chimpanzees? Because you aren't.
