Ayumu, a chimpanzee living at the Primate Research Institute of Kyoto University, has demonstrated in numerous experiments his extraordinary short-term memory which even adult humans cannot surpass. Now we have remade one of the famous tasks completed by Ayumu for you to test your active memory ability! Your goal in this game is to memorize the positions of the squares from 1 to 9, then click them in the same order. At each level of the game, click the circle on the screen to start, then 9 squares marked with numbers 1 to 9 will be shown for a very short time. After the squares are flipped face-down, you need to click the squares in the correct order of 1 to 9. Accept Ayumu's challenge now and see if your short-term memory is more powerful than his!
