Shade some cells so that each orthogonally connected group of shaded cells is in the shape of a square and the remaining unshaded cells form one orthogonally connected area. No 2x2 area may be entirely unshaded. Clued cells must be shaded, and indicate the number of shaded cells in the diagonally connected group they belong to
