Test your wits against the intelligent simians in this addictive app created out of Mekanism promoting the upcoming Planet of the Apes reboot Apes Will Rise, out of 20th Century Fox. The game mimics a memory test Japanese researchers performed on chimps who had been taught the order of Arabic numerals. Players are required to tap numbers strewn across a screen in their numeric order, after they've been covered off by white boxes. The game features three difficulty levels-Easy, Hard and Ape-the latter which reflects the real speed of the original game played by the chimpanzees.
