Show mistakes when checking


  • Objective / Rules
    - The completed grid is a sea of Blue water with White islands.
    - You have to find all of the islands.
    - The numbers tell you how many White squares are in each island.
    - Every island is isolated from every other island vertically and horizontally but they may touch diagonally.
    - Any Blue water squares can be reached from any other (i.e. they are connected).
    - 2x2 Blue water blocks are NOT allowed (2x2 White island blocks are).

  • Help

  • Mouse Usage
    Left-click = Blank >> Water >> Island >> Blank.

  • Checking
    If you click 'Check' the system will check for incorrect squares. If 'Show mistakes when checking' is checked they will be marked with a red X.

  • Uniqueness
    Each puzzle has exactly one solution, which can be found using logic alone and no guesses are ever required. If you think you've found another solution, then please double check the rules. If you still think you've found another solution, then please email us and we'll try to help.
