Loop (Shaded) (1030)
Instruction:
Shade some cells so that no shaded cells touch along an edge. Each number to the top and left of the grid reveals the number of shaded cells that must be located in that row or column (including any that might be given for you).
You must be able to draw a single closed loop (without intersections or crossings) through the centers of all unshaded cells. Loop paths must be orthogonal.
