Shade a single group of orthogonally connected cells in each region so that the remaining unshaded cells form one orthogonally connected area. Shaded groups may not share a bold border. Regions with numbers must contain the indicated amount of shaded cells. Unclued regions must contain at least one shaded cell. A line of consecutive unshaded cells may not cross more than one bold border Solve on Puzz.link
