Loop The City
You've been given a city with some of the numbered buildings in it and a tough task. You must construct a road that loops the city. The road must not branch and there must only be one loop. The number on a building indicates the number of faces of this building facing a road. Click an edge to create a road, click again to mark that edge with an X, indicating that an edge has no road. The faster you complete the road, the higher your score. There's a fun challenge waiting for you when you Loop The City!
