Shoalfire

Shoalfire is a naval battle at dusk. Two fleets of five ships hide on 9 by 9 seas, never touching each other. Take turns firing one shell: a white ring marks a splash, flames mark a hit, and a ship goes down when every square of it is burning.

Your edge is the sonar. Every fourth shot charges it, and a ping counts the unhit ship squares in a 3 by 3 patch, so you can sweep the sea instead of guessing.

• Four admirals: random fire, hunt and target, a checkerboard search, and a probability map over every placement still possible
• Sonar pings that count ship squares in a patch
• Shells that arc across the sky, with splashes, fire, smoke and a shake when a ship goes down
• Ships never touch, so a sunk ship also clears the squares around it
• Shuffle your fleet as often as you like before the battle
• Made for phones held upright: their sea on top, yours below
