Mean 18 is the name of a series of computer golf games released by Accolade in the late 1980s and early 1990s. It is also the name of the first game in the series. In the early 1990s, the series was phased out by Accolade's Jack Nicklaus series of golf games, which arrived in 1990. The game was designed by Rex Bradford with graphics by George Karalias, both of the small game development company Microsmiths.
