In Kaos the player guides a little man in a vertical maze of moving platforms. There are dollar coins which are worth points. Monsters will chase and eat the player character. The player is also killed if he is caught between a platform and the edge of the screen or falling down the bottom of the screen. A power icon will transform the little man into a warrior, enabling him to kill the monsters. Upon killing all the monsters, the player goes to the next maze. Each maze gets progressively harder to navigate with additional monsters and less power icons.
