The object of the game is to be the first player to build a 16-floor building. At the same time, players will attempt to prevent their opponents from reaching their 16th floor. The first player to build their 16th floor and also hold the "Finished Building" card will be the winner. Apart from the tiles used for the buildings, there are also cards which are used to defend against other players. Attacks are also played through cards, including snowstorms, worker strikes, and lack of concrete, among other problems. —user summary
