In Battleship, players take turns placing their ships on a grid. Ships can be placed either horizontally or vertically but cannot overlap.

The standard ships include one aircraft carrier (5 spaces), one battleship (4 spaces), two cruisers (3 spaces each), two destroyers (2 spaces each), and one submarine (1 space).

No, if you have already guessed a coordinate and it has been marked as a hit or miss, you cannot guess that coordinate again during the same game.

You win the game by sinking all of your opponent’s ships before they sink yours. This means marking every square that each of their ships occupies.

A good strategy is to start with random shots to get an idea of where the ships might be, then focus your shots around confirmed hits until you sink a ship.

Traditional rules of Battleship do not allow communication between players, as it is meant to be played silently. However, some variations may permit limited communication.

If both players manage to sink each other's ships simultaneously, it typically results in a draw or tie, though this scenario is rare.

Online versions may have slight variations, such as quicker turn times, chat features, or additional game modes like timed games or team play.
