Aim of Nurikabe:
Blank out cells to create "islands" of cells. Each "island" must include one - and only one - numbered square. The total number of squares in the island must be equal to the value of the numbered square. All squares that are not part of an island must be connected - either vertically or horizontally - to form a single shape. There must not be any 2x2 blocks of squares not connected to an island.
How to play Nurikabe:
Click on any of the undecided squares to change the colour. A yellow colour indicates that the square is part of an island and a grey colour indicates that it is not part of an island.
