Battleship War is a free online HTML5 Battleship Game. This game features the ability to play against robots, or real players online. Choose between the classic mode and advanced mode. Battleship War uses the same rules as classic Battleship, where players take turns firing shots at their opponents board to try and sink all of their ships. The player who sinks all of their opponents ships first wins. This game uses a larger board than the original game, and 6 ships.
