Nurikabe Scrabble (1150)
Instruction:
Shade some empty (non-numbered) cells gray (leaving the other cells white) so that the grid is divided into nonoverlapping regions; cells of the same color are considered in the same region if they are adjacent along edges. Each given number must be in a white region that has the same area in cells as that number. Each white region must have exactly one given number. All grey cells must be in the same region. No 2×2 group of cells can be entirely shaded grey.
Then, put exactly one letter into each grey cell so that the given words can be read either across (left-to-right) or down (top-to-bottom) in consecutive cells in the grid. Every word must appear in the grid exactly once, and no other words of two or more letters may appear in the grid (that is, if two grey cells are adjacent orthogonally, then there must be a word that uses both of them). Every word must have either a white cell or the edge of the grid before and after it. Some letters (in grey cells) may already be given for you.
