Gunnery
Gunnery is the duty puzzle responsible for loading a ship's guns. When a cannon is loaded in the puzzle, a cannon becomes available to the commanding officer to shoot in battle nav.
Basic Gameplay
The goal is to correctly load the four guns, as quickly as possible. The gunnery pieces are sent out in all four directions from the wooden barrel, in random order, until there are two of each on the board. [Exception: When the ship runs out of shot, you will stop getting shot pieces.] When a piece is used, another of that type will be sent out the barrel. Pieces travel in a straight line until they strike an obstacle, at which point they turn right. If turning right is impossible, they turn left, and if neither is possible, they reverse direction.
The pieces must be loaded in correct order: powder, wad, shot. The fourth piece, the bucket, is used to clean out a gun after it has been fired, or if the wrong piece has been placed in a gun. This is accomplished by placing arrows to direct the flow of pieces. An arrow can be placed facing any of the four cardinal directions, and a piece travelling over the square containing the arrow changes to that direction. It is necessary to place an arrow in front of the gun barrel to finally move the piece into the gun.
When playing the gunnery puzzle in the navy, the guns will not be fired, so after loading the four guns, you should abandon the game, go back to the deck, and reenter the puzzle. When you reenter, the guns will be empty again.
