Landmarks are the most learnable category in any geography game, because they are famous precisely because they look distinctive. You do not need to know the exact coordinates of the Eiffel Tower: you need to know it is in Paris, and that Paris is in the middle of northern France. That alone scores well over 900.
Landmark questions are scored on distance to the real spot, like city rounds. Because landmarks sit inside compact cities or clearly defined natural sites, a pin in the right city is usually a strong score, and only the final few hundred metres separate 900 from 1,000.
A few landmarks in the game are treated as whole areas rather than single points — the Sahara Desert, the Amazon Rainforest, the Great Barrier Reef, the Serengeti, the Everglades, the Okavango Delta, the Ngorongoro Crater, Lake Baikal and the Grand Canyon. For those, a click anywhere inside the area counts as a perfect answer.
Landmarks overlap heavily with cities, so the city-name patterns guide and this one reinforce each other. If you want the wider picture, reading the map for clues is the next step.
