According to the front of the box, Sea Duel is a "Naval Battle of Wits." This is a very interesting strategy game involving a submarine and a battle ship. The player can choose to control either vessel. When controlling the submarine the object is to torpedo the battleship; when in control of the battleship, the object is to hit the tiny sub with a deadly depth charge. Players plot their moves on the battle grid and then the naval dance plays its self out. This game is for one player or two!
