The Missions & Abilities expansion includes three modules. Missions: Two missions are randomly selected each game, and give players more ways to earn points. New Abilities: Six new special abilities are added to the game. They may be mixed with the original abilities, or players may use the Advanced Rules to form an abilities market. Joker Tiles: Joker tiles may be placed over already placed pieces to add a window, or they may be placed on the facade, where they are wild for every color. Originally included in the Copenhagen Kickstarter edition of the Deluxe and Collector's edition. —description from the publisher
