Rules:
On a rectangular or square grid there are points at some intersections of the grid lines. Blacken some "borders" between the cells so that at each given grid point, exactly three black lines must meet. In all other network points, no more than two black lines may intersect. All cells in the grid form a single closed loop with no ends (path) - exactly one cell.
