Hex Masyu with Branching

(Published on 26. April 2013, 04:39 by kiwijam)

I have made an example puzzle of the "Hexagonal Masyu with branches" type, as seen in the Logic Masters 2013 Qualification round (http://www.logic-masters.de/LM/qualifikation.php).
I hope it is a similar difficulty to the actual puzzle (by Sebastian Matschke).

Instructions:

Draw a path system, connecting the centers of adjacent cells, passing through all cells with symbols. The path may pass straight through a cell or make a 120° angle, however 60° angles are not allowed. The path may branch out (any number of times); that means, from one cell lines are drawn to three adjacent cells, making three 120° angles (again, 60° angles are not allowed). All parts of the path must be connected, and there must not be any open ends.

The symbols have the following meaning:

  • white circle: The path must pass straight through, and in the next cell in at least one direction it must make a turn or branch out.
  • black circle: The path must make a 120° angle (not a branch), and it must go straight through the next cell in both directions.
  • branching symbol (Y): The path must branch out, in the directions indicated by the symbol.
  • asterisk: The path must branch out, in either of the two possibilities according to the rules mentioned above.
Note that not all branching points are given.

Solution code: For each row from top to bottom, enter the number of unused cells in that row.

Puh - ohne die Unterstützung beim Stammtisch hätte ich mich wieder und wieder verheddert...
Jetzt konnte ich auch die Schönheit dieser Konstruktion erkennen.

Awesome, thanks! The competition puzzle probably turned out a little easier?

Knifflig! Und eine sehr hohe "Verzählwahrscheinlichkeit"... :-(

Wegen der nicht eingezeichneten Verzweigungspunkte, muss man sich sehr konzentrieren, dass man nichts übersieht.

To say it like Arvid, this puzzle is "kniffig und gemein", and in your words "strange". :-) Thank you very much, I learned a few elementary things. Silke
