Country Road
Country Road is puzzle game.
The rule is the following.
The square grid is divided into "rooms" of various shapes.
Some of these rooms contain a number.
The object is to draw a closed loop in the grid, entering and exiting each room once.
A room with a number must have that many squares used by the loop (a room without a number may have any number of its cells used).
Lastly, orthogonally adjacent unused squares must not be in different rooms.
