The game "Battleship" helps to distract from everyday worries and spend time in sea battles, "fighting" with the Opponent on the field in the "cage".

Your field and the Opponent's field looks like a square of 100 cells (10 cells horizontally and 10 cells vertically).
Four types of ships participate in battles:
1) battleship: consists of 4 cells located side by side on the same line;
2) frigate: consists of 3 cells located side by side on the same line;
3) corvette: consists of 2 cells located side by side on the same line;
4) galley: consists of one cell.

The ships form a squadron.

Before the start of the battle, you can choose one of the five squadrons:
1) Operational-tactical:
- one battleship;
- two frigates;
- three corvettes;
- four galleys.
2) Tactical reinforced:
- one battleship;
- four frigates;
- three corvettes;
- two galleys.
3) Tactical:
- three frigates;
- four corvettes;
- three galleys.
4) Operational:
- one frigate;
- four corvettes;
- five galleys.
5) Intelligence:
- ten galleys.

The choice of a squadron (yours and Opponent) is carried out by clicking on the scheme of the squadron. By pressing several times, you can select the desired squadron.

When you start the game, the program itself places the ships in your field and in the Opponent's field. You can change the placement of ships in your field.

When the device is oriented vertically, above the Opponent's field, a diagram of the Opponent's squadron of ten ships is displayed, the image of the ship and a small copy of your field. During your turn, the opponent's ship is displayed, and during the opponent's turn, your ship is displayed. At the moment of a miss, disappearance, damage or destruction of the ship, the image of the ship changes. The destroyed ship is crossed out on the squadron scheme.
With horizontal orientation, your field and the Opponent's field are located in the same horizontal plane. Between the fields are the real time clock. Above each field is displayed the scheme of the squadron and the image of the ship.
An opponent for you can be the program "Sinbad the Sailor" or "Sea Wolf", which differ in the strategy of warfare.

The "Flying Dutchman" option turns one galley in the Rival squadron into a "ghost ship", which requires up to five hits to destroy. On the scheme of the squadron, the "ghost ship" is marked with a blue background.
At the time of the flight of the core to the location of the "ghost ship", the ship, in an invisible way for you, moves to a free place that you have not fired at yet. Such movements can be up to 5 times. In the event of another hit, if it is the 5th hit or there is no free space to which the ship can move, the "ghost ship" is destroyed.
The moment of a shot, damage, destruction of the ship and the moment of a miss are accompanied by sound and visual effects. Each of these events has its own unique sound and visual effect.

Sound, color effects, and comment output can be enabled or disabled.

A ship hit is marked with a red "cross" in the corresponding cell, and a miss is marked with an orange "splash". A destroyed ship is highlighted with a red frame. Hitting the location of the "ghost ship", which managed to "hide" and change its position, is marked with a blue "splash" and the message "Hidden".
Shots are fired alternately: first you, until the moment of a miss, then the Opponent. The first one to destroy all enemy ships wins.
After the end of the game, all the opponent's ships are displayed on his field. "Ghost ship" is highlighted with a blue background.
