Rules: Variation of Battleships and Yajilin. Place the fleet of ships in the grid so that different ships are not in adjacent cells that share an edge or corner. The grid contains internal clues (a number and an arrow) that show how many ship segments are in the indicated direction. All remaining white cells that do not contain a ship segment must be able to form a single loop, as in a Yajilin puzzle.
