How to play Sea Battle

  1. Place your five ships on your grid: drag a ship to move it, click it to turn it, or press Shuffle ships for a random layout. With a keyboard, Tab to a ship, move it with the arrow keys and press R to turn it. Then press Start battle.
  2. Click a square in enemy waters to fire. A red peg means a hit, a dot means a miss. When every square of a ship is hit, it sinks and its outline shows.
  3. You and the computer take turns. The first to sink the other side’s whole fleet wins.

Tips for winning at Sea Battle

  • Hunt on a checkerboard. Every ship covers at least two squares, so firing at every other square still finds them all with half the shots.
  • Finish what you start. After a hit, sink that ship before hunting elsewhere. Two hits in a row tell you which way it runs.
  • Use the sunk ships. When a ship sinks, you know its length. Cross it off and look for the longest gap the remaining ships could fit in.
  • Spread out your fleet. Ships in a cluster can be found together. Keep them apart and avoid lining them up along an edge every game.

About the game

Sea Battle is a guessing game for two players, each with a fleet hidden on a 10 by 10 grid. Players take turns calling squares to fire at, and the other side says hit or miss, until one fleet is sunk. It began as a pencil-and-paper game and became famous as the board game Battleship. This version plays against the computer at three levels and keeps your wins and best game on this device.
