LOOK UP. THINK IT THROUGH.
Know your skyscrapers?
Three ways to test yourself. Recognise an outline, estimate a height or trace an engineering idea. Ten questions per round, with explanations after every answer.
Silhouettes are simplified outlines of the top ten, shown at a common display size to avoid giving the height away. Best scores stay on this device; no leaderboard or account is involved.
