Then draw a single closed loop passing through all fields not occupied by ships. The loop must make a 90° angle at all black circles and go straight for at least two cells in both directions before turning again. The loop must go straight through all white circles and make a 90° angle in at least one of the neighboring cells.
A black circle may belong to the Masyu or (as a one-field ship) to the battleship-fleet.
Solution code: Row 3 and column 6, from left to right resp. top-down; L for cells with a bend in the loop, I for cells with the loop going right through, and S for ships
