Puzzlerium Tour: Nurikabe





Theme: Odd vs Even

Rules: Shade some cells so that all shaded cells are connected and no 2×2 square is completely shaded. Cells with numbers cannot be shaded. Each group of connected unshaded cells forms an island; islands can touch each other diagonally. Each island must contain exactly one given number that indicates the number of cells inside the containing island.
