Sea Battle

Each admiral hides a fleet of five ships on a 10×10 sea: Flagship (5), Frigate (4), Destroyer (3), Submarine (3) and Patrol boat (2). Sink the whole enemy fleet before yours goes down.

Deploy your fleet

• Tap a ship in the dock, then tap a square on your sea to place it. Press Rotate (or R) to switch between horizontal and vertical.
• Drag a placed ship to move it, or tap it to pick it up again. Random deploys the whole fleet for you.
• Ships may touch but not overlap. Press Start battle when all five are at sea.

Battle

• Tap a square in Enemy waters to fire. A white splash is a miss, a flame is a hit. When every square of a ship is hit it is sunk and revealed.
• Keyboard: arrow keys move the crosshair, Enter or Space fires.
• Rules option: shots alternate, or a hit earns another shot.
• 2 Players: pass the device between turns — a cover screen hides each fleet.

Tips

Search in a checkerboard pattern: the smallest ship is two squares long, so you only need to hit every other square to find it. Once you hit, probe the four neighbours to find the ship's direction. The Hard computer uses a probability map, so spread your ships out unpredictably.
