Loop the City Daily Game

• Create a single road that loops the city. The road must not branch and there must only be one loop.
• The number on a building indicate the number of sides of that building that are facing the road.
• Click to create a road, click again to mark an edge to indicate that there is no road.

In this game there will be a city with some of the numbered buildings shown. Your task is to 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 at an edge to create a road, click again to mark that edge with a cross to remind yourself that this edge do not have a road. The faster you finish the game, the higher the score.

Basic Moves

In this game there is no need to guess nor use complex logic, all you need are the following 6 moves:

1. If the number of roads beside a building is already equal to the number marked on the building, then cross out the remaining edges
2. If the number of edges that are not crossed out is equal to the number marked on the building, then mark the remaining edges with roads
3. If an opening of a road can only go to one direction, then mark that direction with a road
4. Cross out the edges joining the middle of the road
5. If all but one of the remaining edges leading to an intersection are crossed, then cross out the remaining edge
6. If marking an edge with a road will form a premature loop, then cross that edge out
