Each level costs money – Trade Mania 2 Review

The game itself is five stars. However, the second and third cities cost 20 gold bars each to unlock, and these gold bars are in-app purchases. Some gold bars are provided already and you can win some by beating the level, but it ends up being about a $5 app. Let me pay the money up front and have all levels instead of being suckered in and then paying the money.
