Sea Battle

A sea battle game in which you call squares on a 10 × 10 grid to find and sink the five hidden ships of your opponent. Play against the computer or with two players passing one device.

How to use

1. Under "Game settings", choose the "Opponent", the "Computer level" and options such as "Ships may touch" and "Fire again after a hit".
2. Drag the ships onto the grid and tap a selected ship again to rotate it, or press "Random placement".
3. When all ships are placed, press "Start the battle". With two players, press "Done placing" and hand the device to the other player.
4. Tap a square in "Enemy waters" to fire. A dot is a miss, ✕ is a hit, and dark squares are sunk ships.

How it works

• The fleet is a Carrier (5 squares), a Battleship (4), a Cruiser (3), a Submarine (3) and a Destroyer (2). You win when you hit all 17 squares of the other fleet.
• With "Ships may touch" off, ships need at least one empty square between them, diagonals included.
• The computer fires anywhere on Easy, follows a ship after a hit on Medium, and on Hard fires at the square where the remaining ships are most likely to be.
• The game in progress and the "Fewest shots" record for each level are saved in this browser.

Questions and answers

What are the rules of a ship guessing game?

Each player hides a fleet, and the players take turns firing at one square of the other grid. The first player to sink every ship of the other fleet wins.

What is the fewest number of shots to win?

The fleet covers 17 squares, so a game without a single miss takes 17 shots. Accuracy is the number of hits divided by the number of shots.

With two players, can the other player see my ships?

The screen is covered after placing and after every turn. The next player must press "I'm ready" before the next screen opens.
