Battle Fleet Solitaire (A Game of Naval Strategy)

Do you remember the old game of battleships? These puzzles are a solitaire version based on that idea. The object of each puzzle is to find the locations of the 10 ships in the fleet hidden in a section of ocean represented by the 10-by-10 grid. The fleet consists of one battleship (four grid squares in length), two cruisers (each three squares long), three destroyers (each two squares long), and four submarines (one square each). The ships might be lying horizontally or vertically, but must not appear in adjacent squares, even diagonally. Numbers along the side and top of the grid show you how many parts of the ship can be found in each row or column. Click on each cell multiple times to set different parts of ships.

The puzzles are given six ranks, indicated on the top of the puzzles. There are a total of 108 puzzles starting from easiest to hardest.

The levels are...

Level 1-10 Seaman
Level 11-30 Petty Officer
Level 31-50 Ensign
Level 51-70 Captain
Level 71-90 Commodore
Level 91-108 Admiral

A salute and a tip of our cap to anyone who can solve all the Admiral puzzles. Good luck and ahoy!
