Frogger

Frogger (フロッガー (Furoggā)) is a 1981 arcade game developed by Konami. It was licensed for North American distribution by Sega-Gremlin and worldwide by Sega itself. It is regarded as a classic from the golden age of video arcade games, noted for its novel gameplay and theme. The object of the game is to direct frogs to their homes one by one by crossing a busy road and navigating a river full of hazards. The Frogger arcade version is an early example of a game with more than one CPU, as it used two Z80 processors.^[2]
