About this game

Compare two skyscrapers and choose whether the building on the right is higher or lower. Each correct answer extends your streak. One mistake ends the run.

Understanding the comparison

Spires count, antennas do not. A building’s silhouette and number of floors can help, but the photographs are not to scale.

How this measure is defined

We use architectural height from the lowest significant outdoor pedestrian entrance to the architectural top, following CTBUH. Only completed buildings appear; observation towers are excluded. Values are rounded to metres and pairs differ by at least 10 m. Individual sources are available in How to Play.
