[edit] Rules
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. 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). Once the circuit leaves a room, it may not reenter it. Lastly, adjacent unused squares must not be in different rooms.
