Bayesian Battleship

1. The computer has hidden five ships on its 10×10 board: 5, 4, 3, 3 and 2 squares long. Yours are on the right.
2. Tap a square in Enemy waters to fire. ✕ is a hit, a dot is a miss. Hit every square of a ship to sink it.
3. You and the computer take turns. Sink the whole fleet first to win.
4. Turn on Heat map to see the chance each square holds a ship; the gold ring is the best shot. Last shot's effect shows how your last shot changed the map.
5. Tick What the computer believes to see its heat map over your own fleet.
