The game offers the chance to earn scrolls which can be used to temporarily unlock expansions which you haven’t purchased, these unlocks are available for 24 hours after using a scroll. I say ‘partially’ because the single player modes have different scenarios, and only the basic setup and rule scenario is unlocked this way, the others must be unlocked via purchase. The lone exception is the First Island single player mode which can be partially unlocked by following a series of introductions which begin when you first start the app.
Everything else, from the base single player, to multiplayer, and even just four player games of any type, all need to be unlocked with coins which are purchased via in-app purchase, much more on those later. The modes you can play for free in the base game are: First Island (Free match and Custom match, three player only), Rivals for Catan (Free introduction match), and the tutorial for all five games. First Island adds a Free match option (which is free online play) while Rivals for Catan adds a free introduction game. The common play modes across the five games are: Singleplayer, Auto match, Custom match, and Tutorial.
