Battleship Puzzles by KrazyDad

Here are hundreds of free Battleship puzzles suitable for printing.

Battleships, also called Bimaru or Battleship Solitaire is a solitaire version of the classic strategy game, in which you must hunt down and sink a fleet of enemy ships.

Each puzzle contains a row and column of numbers which indicate the number of squares in each row/column that contain a ship or ship segment. Most squares are empty, for you to fill in, but some will be givens, which indicate water, specific ships, or parts of ships. No ship may touch another ship, even diagonally.

Each collection is ordered by difficulty, with the easiest puzzles in Book 1, and the hardest in Book 100. If you are new to these puzzles, I recommend you start with Book 1. The larger sizes tend to be harder, and the 12x12s in particular can be quite challenging.

The "Surprise Attack" collections contain different fleet arrangements for each puzzle. The rest of the collections use identical ship layouts within each collection.
