How to Play
Nurikabe starts with a grid containing numbered cells. Each number is an island that must contain exactly that many white cells, including the numbered cell itself. Islands cannot touch orthogonally. The remaining cells form a black ocean that must be connected and cannot contain any 2x2 square.
The puzzle is solved when all islands are correctly sized and separated, and the ocean is one continuous region without illegal pools.
