Players must place their ships on their grid. A ship occupies a certain number of adjacent cells in a straight line (horizontal or vertical). Two ships cannot touch themselves.
Once positioned the ships, the game proceeds in turns. The player whose turn "fires a shot" by clicking on a cell. If the cell contains a ship opponent will see an explosion on the grid, otherwise the turn passes to the other player. When a ship is sunk, it is drawn on the grid.
The winner is the first player to sink all the ships of the opponent.
