Yin Yang on Arrows 3
(Eingestellt am 23. Juli 2023, 15:17 Uhr von farodin64)
Eine Anmerkung aufgrund einiger Kommentare. In diesem Puzzle ist der Yin und Yang Teil eine Starthilfe für den nachfolgenden Sandwich-Teil, d.h. auch wenn der YY-Flow korrekt und eineindeutig ist, ist nicht der gesamte YY-Flow zum Ausfüllen aller Ziffern notwendig. Gerne könnt Ihr den YY-Flow natürlich trotzdem komplettieren.
Regeln
- Es gelten die normalen Sudoku-Regeln.
- Yin Yang: Schattiere einige Zellen so, dass alle schattierten Zellen orthogonal verbunden sind und alle nicht schattierten Zellen orthogonal verbunden sind und kein 2x2-Bereich vollständig schattiert oder nicht schattiert ist.
- Arrow: Ziffern auf einer Pfeillinie ergeben in der Summe die Ziffer im angehängten Kreis. Alle Kreise sind schattiert und zeigen die Anzahl der nicht schattierten Zellen in den bis zu 8 umgebenen Zellen an. Alle Pfeillinien sind nicht schattiert.
- Sandwich: Zahlen außerhalb des Rasters sind die Summe der Ziffern zwischen der Eins und der Neun in der Zeile/Spalte.
Links
Lösungscode: Zeile 5 (von links nach rechts), danach Spalte 5 (von oben nach unten)

This was quite challenging for me as a beginner, took almost 2 hours! The logic was beautiful, most of the challenge was figuring out which rule or clue would lead to the next deduction. It didn't help that I always exhausted every option before sandwich sums, I was dreading those! I learned a valuable lesson: if you are stuck for more than 5 minutes, it is time to look at a new clue. I am sure there was a much easier way to solve this, but I am pleased that I was able to at all!

My first yinyang!! Really enjoyed the shading and all of the choke points

This is a really good puzzle. I enjoyed it. Unlike few others I needed yin yang to complete the sudoku. In fact I was thinking there could be multiple paths possible for yin yang, but at the end, there was only one solution. That was satisfying.
But I think this is more than 2* difficulty. I am putting 3*.

Well, another of yours I've broken multiple times, but as ever, I get there in the end! Thank you for another mind bending, thought provoking, sudoku improving puzzle! You are single handedly teaching me Yin -Yang!

Very nice puzzle from start to finish! I thoroughly enjoyed completing the yin yang logic, even if doing so was not required for the solution code.

Thank you :-)

Agree with the other commenters that the YY part was not as well-integrated as it could have been.
I did use YY logic to solve the puzzle, but I still ended up with 20+ cells unshaded; that's about a third of the puzzle where the YY logic doesn't matter at all.
IMO, it's not about whether the solution code asks for only shaded or only unshaded cells. It's that the YY logic should be more important to actually figuring out the solution of the puzzle.

I love shading puzzles! This one was fantastic. I was a bit stumped for a while, after the break in the solve was smooth:)

I'm glad you enjoyed it :-)

Fun, although I ended up not needing to complete the yin-yang shading in order to solve the puzzle. Maybe I made a leap of logic somewhere that I wasn’t supposed to.

@tobymgk: Hi, shading of a few cells may not be necessary to fill in all the digits. But the Yin Yang path is unique, that's important. In addition, the Yin Yang serves as a starting point for the second part of the puzzle. I hope you still enjoyed it.
OK, a harder solution code check would be possible e.g. using only digits of unshaded cells. I think about that next time...
