Standard regional yajilin rules: Blacken some cells so that you can 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. The grid is divided into regions by thick borders; a number in a region indicates exactly how many cells in that region must be blackened. Numbered cells may be blackened. The number of blackened cells for a region without a number is for you to determine.
