Domino Nurikabe Shade some cells black so the black cells form a tapa wall. No cell with a number may be shaded black. The black cells divide the white cells to several polyominoes (islands), all maximal (cannot be extended). Each island must have exactly one number that tells the size of the island. In addition, it must be possible to partition the black cells to dominoes. Such partition need not be unique, as long as there exists at lest one.
Answer key: Enter the lengths of the lines of black cells in the marked row/column. If the row/column has all/no black cells, enter 0.
