Here are the rules for “The Battleship” game (in case you do not know).
First, place ships on your field. Ships are rectangles 1 section wide and 1 to 4 sections long. Click on your field to place a section of a ship. There should be exactly 1 ship 4 sections long (carrier), 2 ships 3 sections long (cruisers), 3 ships 2 sections long (destroyers) and 4 ships 1 section long (submarines) – 10 ships in total. Ships cannot touch each other – side to side or corner to corner.
When you are done placing ships, press “Go” button and it will bring you to the second phase of the game – shooting.
To shoot: point on a cell within opponent's field and click. If your shot lands on an empty spot, this cell will be marked with a point and turn is being passed to your opponent. If the cell is occupied with a section of enemy ship, it will be marked with a character and you will be given an opportunity to shoot again. If it was the last section of a ship, the whole sunken ship is marked with dark gray color and surrounding area is marked with light gray – as a reminder for you that no other enemy ships can be located there.
