The object of Battleship is to try to sink all the other player's ships before they sink yours. 1. Both players put all 4 ships somewhere on the board. Do not change the size and do not let them hang off the board. 2. Take turns guessing our coordinates. If a player guesses right, say "hit". If they guess wrong say "miss". When all of the squares that one of your ships occupies have been hit, the ship will be sunk. Say "You sunk my battleship!".
