Setup
Battleship is a two-player game in which the players take turns trying to find pre-placed ships on their opponent's game board. The Battleship game board opens and locks into two pieces connecting to form a 90-degree angle. The board that is perpendicular to the table represents the opponent's board, with the board parallel to the table being the player's game board. The two players sit facing each other with the game boards open back to back. This keeps the players from seeing the other one's board. Prior to actual play, each player arranges his "fleet" of five ships in a random order on his side of the game board.
The playing grid is made up of coordinates of one letter and one number. The letters range from A to J, and the numbers from one to 10. Each ship will take up several spots on the playing grid. The ships can be placed in any horizontal or vertical position on their game board. It is not possible to place the ships on the board diagonally. Once the game begins, the ships must remain in the beginning position for the duration of the game.
Game Play
Players take turns calling out letter and number coordinates in an effort to sink the other player's ships. Each player gets several red and white pegs to represent the shots taken on each board. A red peg is used on both of a player's boards to represent a hit, either on their own ship or on an opponent's. A white peg is to be used for a miss. When a ship is sunk, the player must inform his opponent that a ship has been eliminated. The game concludes when one player has had all of his ships sunk.
