There are two mainboard editions, one typically associated with Milton Bradley, and another typically associated with Ravensburger. The primary difference between these is in the numbering of the stations: five stations are numbered differently, with 108 missing from the Milton Bradley boards and 200 missing from the Ravensburger boards. There are also minor differences in the routes, such as a bus line between stations 198 and 199 that is changed to a taxi line in later editions, and the removal of a taxi line between stations 13 and 14 sometime after the renumbering.
