Sink the Ships

Place your five ships, then take turns firing at the enemy's waters. A ship sinks when every one of its squares is hit, and whoever sinks the whole enemy fleet first wins.

Play against the computer on three difficulties: Easy fires mostly at random, Normal hunts in a checkerboard pattern and finishes every ship it hits, and Hard works out where your ships are most likely to be. Beat all three to complete the game.

Or play splitscreen with a friend on one screen. The fleets are placed one after the other behind a "look away" screen (or deployed randomly without being shown), and during the battle the screen only shows what both players may know. Hold "My fleet" to check your own ships. Both players have their own target grid and keys, and tabletop mode turns Player 2's side upside down for playing face to face over a tablet.

Optional rules: a bonus shot after every hit, and ships that may not touch.

Your statistics and the unfinished match are saved to the cloud when you are logged in.
