What is the best-selling board game in the world?

If we exclude chess (this game is so old and sales figures are not known), Monopoly is the best-selling game in the world. This is quite surprising because Monopoly was (and sometimes still is) banned in the communist part of the world for a long time. More than 200 million copies of Monopoly have been sold since 1935. This includes all variations, such as Star Wars Monopoly, Football Monopoly and Casino Monopoly.
