battleship (game)
Table top guessing game for two players. Each player has two grids, one grid to place their "ships" (two to five squares in length), the other to "aim and shoot" at the opponent's ships using coordinates. A ship is "hit" once when it occupies a square called by the opponent and is "sunk" when all squares it occupies are hit. The object is to sink all of the opponent's ships before the opponent does the same.
Starting out as a pencil and paper game played as far back as the 1890s under the names Baslinda and L'Attaque, it is best known in board game form with plastic game ship models and pegs on 10x10 grids, first produced by Milton Bradley in 1967.
