Wipe out your enemy's naval forces to assert your authority at sea! Your goal in this game is to sink your opponent's battleships by using torpedoes strategically. When the game starts, your 5 vessels will be placed in the area on the left of the screen, 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 can click the cross button on a ship and drag it to a desired position, or click the reverse button on the ship to place it upright. Note that you need to finish your moves within the given time limit as indicated by the timer on the screen, or you will lose. When you are satisfied with your arrangement, click the OK button above 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 your opponent will then take turns to bomb each other's warships. The positions of your ships will be displayed to you, but those of your opponent 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 ship, a part of that ship 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 player are hit and sunk, the game ends. Can you destroy your enemy's fleet before he gets in your way?
