Polygon: cover the world with cities
Cover as much of the map as you can with triangles.
How to play
Cover as much of the map as you can with triangles. Name any city to put it on the map. Two cities within reach of each other are joined by a line, and three that all reach each other fill in a triangle. Your score is the area your triangles cover in km², counted once where they overlap. You set the reach: about 1,000 km on the world map to start, scaled down for a continent, a country or a region. A city out of reach of everything still counts as a starting point. There's no losing move, so press Give up when you're done and the score stays.
