Country Road is a loop-drawing logic puzzle where a single, non-intersecting loop that passes through all regions is drawn.
The objective is to draw a single, non-intersecting loop, subject to the following rules:
- All regions must be visited by the loop exactly once which travels horizontally and vertically.
- Numbers indicate how many cells in a region the loop visits.
- There must be least one cell visited by the loop wherever there are two adjacent cells in different regions.
