Use the number clues to locate your missing fleet of ships.
How to play
The object of the puzzle is to mark every square in the grid as containing a boat (or part of a boat) or empty water.
The numbers at the edges of the grid indicate how many squares in that row or column contain part of a boat.
Boats never touch each other horizontally, vertically or diagonally.
A few squares containing boats will already be filled in at the start of the puzzle. Use these clues, and the rules above, to start determining which of the remaining squares should be marked as boat or water.
You can see how many boats of each length are left to find in the list under the grid.
If you make a mistake, tapping a filled square a second time erases its contents.
In Standard Mode, the clue numbers at the edge of the grid will turn green when all the squares in a line have been filled and the number of boat squares on the line matches the clue.

Please note that this doesn't necessarily indicate that the boats have been placed in the correct squares on this line. It may be possible to satisfy all the clues in such a way that still breaks other rules (e.g. boats cannot touch diagonally).
In Quick and Super Quick modes, the clue numbers will turn green when a line's boat squares have been filled correctly - tapping a green clue number will fill in the remaining water tiles automatically.

■ Suggest a move
If you're struggling to see a logical move to enter, use this hint. The game will analyse the current grid and automatically fill in a few squares based on the information available.
■ Check for Errors
Use this hint to highlight any squares with incorrect values. These squares will be marked with a red 'X'. Tap a marked square to erase its contents. As there are only two states that any square can be in, it can be deduced that any square marked as an error should be flipped to the other state (Boat or Water).
