Remaining empty squares in a row or column are ship segments: And finally, row F and columns 4 and 5 all have a count of 1 which is accounted for so the remaining squares are also marked with X. Row C has a count of 2 which is accounted for in C4 and C5 so the remaining squares are marked with X. Row A and columns 2 and 7 have counts of 0 meaning they contain no ship segments so all squares are marked with X to indicate water. This technique helps complete rows and columns where ship segment counts are fully accounted for. Remaining empty squares in a row or column are water: Therefore the squares above and below are ship segments (denoted by dots) and three more squares are filled with water. Square F10 is a middle segment of a ship so it must be part of a battleship or a cruiser and must be oriented vertically because it is touching the frame of the gird. We can now place the other end segment and fill the ten squares surrounding the destroyer with water by marking them with an X.

Since the count of row C is two, this ship must be a destroyer. Square C4 contains the end segment of a ship, which means there is another part of the ship in C5. Since submarines consist of one segment, all neighboring squares of H8 must be filled with water by marking them with an X. Let's start with the puzzle below which contains three given ship segments and two given water segments. Fill in ship segments in rows and columns that must have all of their remaining empty spaces filled in order to equal the corresponding number.įill what you know around given ship segments:.Fill in water in rows and columns that have all of the ship segments already in place.Fill in what you know in squares adjacent to given ship segments.The most basic strategy to Battleships solving has three parts: This is either the middle segment of a cruiser, or one of the 2 middle segments of the battleship and the diagonally adjacent squares are filled with water. All other surrounding squares are filled with water. The square adjacent to the flat side must be occupied by a ship segment. It indicates the end of either a destroyer, cruiser, or battleship. This square can be oriented in any of four directions. This square consists of a submarine and must be surrounded by water. In nearly all Battleships puzzles, the contents of a few of the squares have been revealed to start you off. Ships can not occupy adjacent grid squares, even diagonally. The ships may be oriented horizontally and/or vertically in the grid, but not diagonally. The object is to discover where all ten ships are located in the grid. The only available information are numbers telling how many ship segments are in each row and column, and some given ship segments in various places in the grid. Game Rulesīattleships Puzzles exist in several grid sizes and offer endless solving variations, ranging from very easy to extremely difficult and taking anything from 5 minutes to 3 hours to solve.Ī typical Battleship puzzle consists of a 10x10 grid containing a hidden fleet of 10 known ships.
