Naval Battle (Battleship) Strategy

Naval Battle is the classic Battleship game: two 10×10 grids, five ships each. Random shots feel fair, but a system finds ships far faster.

Search in a checkerboard pattern

Every ship is at least two cells long, so it must cover a cell of both colours on a checkerboard. Firing only at one colour finds every ship with half the shots of random guessing.

Once the Destroyer (two cells) is sunk, the smallest remaining ship is three long — you can widen your pattern to every third cell.

Hunt, then target

After a hit, switch from searching to finishing: fire at the four neighbours until you find a second hit, then continue along that line in both directions until the ship sinks.

If a line of hits is longer than the ship that sank, two ships are touching — go back and finish the other.

Track what’s left

The fleet is a five-cell Carrier, a four-cell Battleship, two three-cell ships and a two-cell Destroyer. Knowing which remain tells you which gaps can still hide a ship: a gap of two cells can’t hold anything but the Destroyer.

Place your fleet to survive

Avoid predictable patterns: ships all on the edges, all parallel, or touching each other (one hit can reveal two). Mix horizontal and vertical ships and leave some open water between them. Randomize is fine too — it’s genuinely random.
