The player (left field) plays against the app (right field). Each player has different ships on the 10x10 field - aircraft carriers, submarine cruisers, and sailboats. Each hit is accompanied by noise and destroys sink ships, but their outline remains visible.
Ships can be placed automatically (click on the button with the cruiser on the right) or manually by pressing the corresponding cells in the left field. A click on the cell next to the ship increases its length, and a click on the ship itself removes it from the field. To completely clear the terrain, click the arrow button on the right.
The game begins with the player's first shot to the right field. Enemy ships match the player's in number and size.
