Public worlds are worlds run by the Airline Mogul staff which are open to all players of AM. These worlds usually have the largest numbers of players to compete against. These worlds require 30 tokens to join. However, if you have less than 30 tokens, and are in no other worlds you may join for your remaining tokens.
Generation of Public Worlds
The public worlds are generated when the last world reaches 80% capacity. The specifications are randomly chosen.
