You sank my Battleship!!Battleship is an age-old pencil-and-paper public domain game, kept continuously in print by Milton Bradley (now owned by Hasbro) since 1967.
Each player deploys his ships (of lengths varying from 2 to 5 squares) secretly on a square grid. Then each player shoots at the other's grid by calling a location. The defender responds by "Hit!" or "Miss!". You try to deduce where the enemy ships are and sink them. First to do so wins.
Commercial from 1981
