Battle Ships

Battleships (or Battleship) is a game where each player has a board upon which they can place a number of ships. The boards are 10x10 two dimensional grid.

##Rules of the Game

After each player has placed their ships on their own board they take turns to shoot on the opponents board. In each round, each player takes a turn to announce a target square in the opponent's grid which is to be shot at. The opponent announces whether or not the square is occupied by a ship, and if it is a hit they mark this on their own primary grid. The attacking player notes the hit or miss on their own tracking grid, in order to build up a picture of the opponent's fleet.

When all of one player's ships have been hit the game finishes and the player who has ships remaining is the winner.
