The October 12, 2026 puzzle ran from the Great Pyramid of Giza at 138.5 m to the Golden Gate Bridge at 2.7 km — about 20× apart, drawing on landmarks. The pair furthest apart was round 4: the Golden Gate Bridge is 256× as big as an American school bus.
Answer: Burj Khalifa — 828 m. The Burj Khalifa measures 828 m (height), which is 1.9× as big as the reference, the Empire State Building at 443.2 m.
At 828 metres, Burj Khalifa is the tallest completed building.
