In "Torpedo Away!" you are in command of a U.S. Navy Gato class submarine. It is 1943. You are somewhere in the South Pacific engaged in unrestricted submarine warfare against the merchant and naval vessels of the enemy.
The main goal in "Torpedo Away!" is to maximize your score within a single combat patrol by sinking various enemy surface vessels while avoiding being destroyed by enemy depth charges.
Enemy surface vessels have varying point values depending on their displacement and military value. The ships travel along separate lanes. The larger value targets will be farther out. They are harder to hit because of the lead required and because of closer vessels inadvertently intercepting the torpedo path. See the chart below:
Note: the highest value target is the large troopship. Both because of its cargo displacement and because of the effect of its sinking on enemy morale. The least valuable targets are the destroyers. Even though they are fast and dangerous, they posses neither a large shipping displacement nor large number of personnel.
You start with 24 torpedoes. A perfect score for a combat patrol would be 20,000 points. That represents 24 hits, all on troopships, plus the 200 point patrol survival bonus. If you vessel is sunk by depth charges, whatever score you have is penalized 200 points for losing your vessel and crew.

The gaming area is divided into two basic zones. The demarcation between the two zones lies along the ocean/sky horizon. Above that line is the HUD zone (See next section), below that line is the control zone.
Your submarine is positioned near the bottom of the screen. Tilting the device to the left and right maneuvers your submarine to avoid depth charges and line up to fire a torpedo.
Tapping anywhere in the control zone fires a torpedo. There is a 3 second reload time before being able to fire another.
Above the horizon line, is the HUD area. Here you will be able to track your current score, the percentage of damage you have sustained, and your remaining torpedo count.
Note: the label for remaining torpedo count, turns RED during the reload time. When it turns GREENagain, you are ready to fire.
HINT: If you wait until a torpedo has reached the water line, you will be ready to launch the next one.
At the right side of the HUD area is the pause button. After the game is paused, you can choose to either continue play, or quit the combat patrol and return to the main menu.
Control: End of patrol
The patrol will automatically come to an end, after a delay for any final torpedoes to complete their run, after your submarine is destroyed or has expened all torpedoes.
