Tetra Tetra is a novel challenge where a player can simultaneously play 2 or 4 classic arcade style games! One-for-all, and All-for-one, with one failure to end your try. Test the speed of your mental reaction, context switching and dexterity of your hands with this (perhaps mayhem-ish) difficult game. Global and Weekly leaderboards are provided by Apple. Additionally, there are exclusive games in Solo mode, such as 100 meter Olympic heat game.
