Dottori Kun (ドットリ君) is an arcade tiny maze game developed and manufactured by Sega. A significantly downscaled port of the company's popular game Head On. The basic goal of this game is that you are the arrow and you must go around the field collecting the dots and avoiding the X. Much like Pac-Man, you cannot turn 180 degrees and if you hit a corner, the game will automatically turn you. Button 1 will cause you to move faster when held. Button 2 pauses and unpauses. Hitting the X will kill you and you will have to start back at the first "level". It was created in response to Japan's Electrical Appliance and Material Control Law which required arcade cabinets to include a working arcade game at point of sale and was included in Sega's JAMMA-compatible arcade machines as early as 1990. As Dottori Kun was designed to be both inexpensive and disposable, very few copies of the game have ever seen the arcade floor - most boards are presumed to have been thrown out or salvaged for spare parts.
