How many variations of the board game Monopoly are there?

The exact total is unknown because Milton Bradley/Hasbro licenses the design rights to allow smaller companies to make custom versions of the game (there are New York City and Ohio State University editions, for example).

Parker Brothers, Milton Bradley and Hasbro have released more than 100 official English-language editions of Monopoly. Milton Bradley/Hasbro, which holds the copyright, currently markets 14 variations of the classic board game, and sells 29 related products, such as iphone and computer applications.
