Paper Skyline
21 cities

Where the plane flies.

The 21 cities of Paper Skyline, from Paris to Athens, each with its painting, its history and its two keepers.

Every continent

Twenty-one cities

The 21 cities lie on six continents: seven in Europe, eight in Asia, Istanbul and Dubai among them, three in North America, and one each in Africa, South America and Oceania. Berlin is the farthest north, at about 52.5 degrees north, and Sydney the farthest south, at about 33.9 degrees south.

Each city is painted around one real landmark. The oldest is the Great Pyramid of Giza in Cairo, built about 4,500 years ago. The tallest is the Burj Khalifa in Dubai, which opened in 2010 at 828 metres. Each city also has two keepers to get past, an Elite and a final Boss, so there are 42 keepers in all.
