Sky-scrapers are springing up all around the world. Players also have the opportunity to build sky-scrapers in Sydney, Frankfurt, Hongkong, Sao Paulo, and Cairo. The question each turn is whether to increase the height of one of your own buildings, or to build onto someone else’s building, making it your building. At the end of every six turns, players score for having the tallest building, the most buildings per city, and for each building that a player owns. After four rounds, the player with the most points is the winner.
