Concentration and good judgment are needed to pilot your Submarines to safety and win in this game. A fleet of eight WHITE friendly Submarines is at the BOTTOM OF THE SEA and eight BLACK enemy Submarines are on top. Using 'torpedoes,' the BLACK subs try to destroy the WHITE ones. Both kinds of Submarines can only shoot Torpedoes in a forward direction, and destroy an Opponents Sub at close range.The object of the game is to move your Submarine into close range, (a Red Dot next to an Opponent) swing it around into position to 'shoot a Torpedo.' Moves are governed by the spin of the Dial. When one player has lost all of his Submarines, the other player wins the game. - BoardGameGeek
