Instruction:
Blacken some white cells and then draw a single closed loop (without intersections or crossings) through all remaining white cells. Loop paths must be orthogonal. Blackened cells cannot share an edge with each other. Some cells are outlined and in gray and cannot be part of the loop. Each number to the right and bottom of the grid reveals the number of blackened cells that must be located in that row or column.
