You'll see a Wikipedia article title, photo, and snippet. Place a pin on the map where you think the location is, then confirm.

You earn up to 1,000 points per question based on how close your pin is to the actual location. A perfect score (within 20 km) awards the full 1,000. The further away, the fewer points — the formula drops off exponentially.

The Daily Challenge has 5 questions for a max score of 5,000. Theme packs vary in length.
