Battleship

Battleship is a war-themed board game for two players in which the opponents try to guess the location of their opponent’s warships and sink them. A paper and pencil version of the game dates back to World War I, but most people are familiar with the game through the plastic board game that was first marketed by the Milton Bradley Company in 1967. Since then, the game has spawned various video games and smartphone app variations.
