Linesweeper ("Loop") is played on a rectangular grid. The object is to create a single continuous non-intersecting loop that connects the centers of the grid cells. The numbered cells can't be passed through; the number in the cell means how many of the 8 surrounding cells should contain some part of the solution path. (For example, "0" means the 8 surrounding cells can't be passed through at all).
