Battleship is played on two 10x10 grids, one for your ships and one to track your opponent's shots. Players secretly place their ships on the grid. The objective is to sink all of the opponent's ships by guessing their locations and calling out coordinates. Players alternate turns, calling out coordinates to hit or miss. The game ends when one player's entire fleet is sunk. Battleship combines strategy with guessing. It’s a game of cat and mouse, where each hit brings you closer to victory.
