Battleships Puzzles: 250 Challenging Logic Puzzles 8x8

Battleships is a logic puzzle based on the Battleships guessing game. In a square grid of 8 x 8 small squares, an armada of battleships is located. There is one battleship of 4 squares, two cruisers of 3 squares, three destroyers of 2 squares, and four submarines of 1 square. Each ship occupies a number of contiguous squares on the grid, arranged either horizontally or vertically. The boats are placed so that no boat touches any other boat, not even diagonally. The numbers on the bottom and on the right of the grid show how many squares in the corresponding rows and columns are occupied by ships. Occasionally some squares may contain given ship or water segments as hints to help start the puzzle. The object is to discover where all ships are located.
