Sink the Fleet (Paper Battleship)

Each player draws two identical grids on paper, labeling rows and columns with letters and numbers.

Secretly mark several ships of different lengths on your own grid without showing your opponent.

Take turns calling out grid coordinates to fire at your opponent's hidden ships, marking hits and misses on your second tracking grid.

Your opponent tells you whether each called coordinate is a hit or a miss, and announces when an entire ship has been sunk.

The first player to sink every one of their opponent's ships wins.
