Purge your enemy's naval forces and assert your authority in the sea! Your goal in this game is to sink the opponent's battleships by using torpedoes strategically. When the game starts, your 5 vessels will be placed in the area at the left-hand side, while those of the enemy are on the right. You can arrange the positions of your ships so that they will not be easily located by your rival. You may click the cross button on the right of a ship and drag the ship to a desired location, or click the reverse button on the left of the ship to place it upright. When you are satisfied with your arrangement, click the OK button on the top right of the play areas to begin the game, but bear in mind that your fleet can no longer be moved during the game process. You and the computer will then take turns to bomb each other's warships. The positions of your ships will be displayed to you, but those of the computer are not revealed. You need to deduce the precise locations of the enemy ships according to the directions of their attacks, then click a square in the enemy's play area to shoot. When a torpedo successfully hits an enemy craft, a part of the craft will be on fire. If the bomb misses, a water drop label will appear on the target, indicating the absence of enemy vessels. When all battleships of a side are hit and sunk, the game ends. Declare your victory by launching accurate attacks!
