Masyu Flotte
(Published on 6. July 2012, 12:00 by Richard)
Battleship Masyu
Draw a single closed loop that passes through all circles by travelling horizontally and vertically. The loop must make a 90° turn in all black circles and go straight through both neighbouring cells before turning again. The loop must go straight through all white circles and make a 90° turn in at least one of the neighbouring cells.In all cells that are no part of the Masyu the battleship fleet have to be placed. Ships don't touch each other, not even diagonally.
Solve online in Penpa+ (thx Nick Smirnov!)
Solution code: 1) For every column the number of cells in which the loop makes a 90° angle. 2) For every row the number of cells occupied by ships.

Changed wording of the English instructions and added link for online solving. Thx Nick!

I think that the description is not correct. The loop must make a 90° angle at all black circles and go straight for at least ONE cell in both directions before turning again.

Hi Nick, I think this is a matter of definition. The rules don't state that you have to go straight THROUGH two cells; that would mean you can only turn in the third one. But I will change the English wording into a version that we also used for the recent Dutch championships. There it is stated a bit clearer.

@Andreas: Ich habe das Rätsel gerade nochmal gemacht und mein Lösungscode ist ganz anders. Wenn Du mir Deine Lösung sendest, schaue ich gerne mal drüber.

@Stefan: two of your one-ships are on a masyu-dot (B9 and H8), so that are at least two mistakes...

I always like new Masyu variations. I hope we will have sooner or later another puzzle of this type in the portal.
