In the city above, create one looping road so that each of the cells with numbers in them will have that many sides touching a road. For example, for a cell with a 3 in it, three of the four sides will be a road.
- The road must be one none branching loop, and the loop may not cross itself, or have dead ends.
- The road can only be on the dotted line.
- Squares with no number can have roads touching them too.
How many sides of the cell with a number sign will be touching a road?
The solution will be available on July 1, 2014 here on Shufflenet.
