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.


  1. The road must be one none branching loop, and the loop may not cross itself, or have dead ends.
  2. The road can only be on the dotted line.
  3. 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.
