How to play

A building is named, with a photo (or a quick line sketch if the photo can't load) and a short fact about it — no address or city given. Click the globe where you think it stands, pick its architect, and slide to guess the year it was built — 1,000 points for a close pin, 100 for the right architect, 200 for a close year. Drag to spin the globe, scroll or pinch to zoom.
