How to Play Battleship
Battleship is a classic naval strategy game where two opponents hide fleets on separate 10×10 grids and take turns firing at coordinates to sink each other's ships. The goal is simple: be the first to sink all five of your opponent's vessels. Despite its straightforward rules, Battleship rewards logical deduction, pattern recognition, and a bit of luck.
Game Setup
Each player has five ships of different sizes: a Carrier (5 cells), a Battleship (4 cells), a Cruiser (3 cells), a Submarine (3 cells), and a Destroyer (2 cells). Ships are placed either horizontally or vertically on the grid. They cannot overlap, and they must stay entirely within the board. In this online version, you place your fleet by clicking a starting cell and pressing the R key to rotate orientation before confirming. The computer places its fleet randomly at the start of each game.
Battle Phase
Once both fleets are placed, players take turns firing at a single cell on the opponent's grid. A hit is marked in red; a miss is marked in gray or white. When every cell of a ship has been hit, that ship is sunk and typically indicated with a distinct color or marker. The first player to sink all five enemy ships wins the game.
Strategy Tips
- Spread your shots early. Use a checkerboard or grid pattern to maximize coverage and increase the chance of finding ships.
- Hunt and target. Once you score a hit, fire at adjacent cells (up, down, left, right) to determine the ship's orientation and finish it off.
- Consider ship sizes. A 5-cell carrier needs more space than a 2-cell destroyer. Use the board geometry to narrow down likely positions.
- Place ships unpredictably. Avoid obvious patterns. Mix edge and center placements, and vary orientations to make it harder for the AI to find your fleet.
- Corner and edge play. Ships along edges have fewer adjacent cells, which can sometimes make them slightly harder to fully locate once hit.
History and Popularity
Battleship originated as a pencil-and-paper game played by Russian officers before World War I. It was later commercialized as a board game by Milton Bradley and has been a household name for decades. The 2012 film adaptation and countless digital versions have kept the game relevant. Its blend of luck and logic makes it accessible to newcomers while still engaging for experienced players who enjoy optimizing their search patterns.
Playing Against the AI
Our Battleship AI uses a hunt-and-target strategy: it first fires randomly across the grid until it scores a hit, then systematically targets adjacent cells to sink the damaged ship. This mimics how skilled human players think, making each game a fair and challenging contest. Play free Battleship online right here—no download, no signup, just strategy and fun.
