To play a naval battle, you need to follow the instructions of the cabin boy, first setting the coordinate and then lighting the cannon with a torch. The flotilla with coordinates is arranged similarly to the paper version. The canvas is divided into squares of the same size. The lower and upper parts of the frame are marked with letters of the Latin alphabet from A to J, while the sides of the frame are marked with numbers from 1 to 10. Rotate the left handle and use it to set the desired letter, and use the right handle to set the number. To launch the cannon, tap the red indicator on the back of the cannon with the torch and then the light and sound effect of the shot will work, this will also be reflected on the field by changing the cell from blue (default) to blue or yellow. Blue means that the ball did not hit the ship, and yellow means vice versa.
There are 2 modes available in naval combat: easy and difficult. In the easy mode, you need to hit 5 ships, and in the hard mode, 10 ships.
When all the ships are hit, a mini-cache will open under the cannon. Inside it will be the key to the door with a grate.
