Sum Line Sudoku #2

(Eingestellt am 8. Oktober 2022, 12:57 Uhr von Phistomefel)

Dieses Rätsel ist eine Sudoku-Variante mit Linien, auf denen drei benachbarte Ziffern eine Summe bilden müssen. Hier die Regeln:
  1. Fülle das Gitter mit den Zahlen von 1 bis 9, sodass in jeder Zeile, Spalte und jedem 3x3-Block jede Ziffer genau einmal vorkommt.
  2. Bei jedem Tripel benachbarter Ziffern auf einer Linie muss eine der Ziffern die Summe der beiden anderen sein, z. B. sind 2-5-7, 6-9-3 und 8-4-4 gültige benachbarte Ziffern auf einer Linie. Ziffern können sich auf einer Linie wiederholen, sofern die anderen Regeln das erlauben.
Hier noch ein Beispiel für diese Sudoku-Variante auf einem 6x6-Gitter:

Even with the logic I established in the previous puzzle, and even after seeing what this puzzle is about, it still has a lot of fresh logic to offer. Doing the previous puzzle did help with grasping this kind of restriction, so the difficulty isn't overwhelming for me.

Intriguing constraint! Both puzzles had a plethora of different ideas, which were a pleasure to uncover. Thanks! :-)

I don't normally try Phistomefel puzzles, or generally CTC video puzzles that are longer than an hour, but I decided to give this one a shot. To my surprise I actually found the break-in in not too long. After that the logic flowed really really nicely. Awesome puzzle, super happy to have solved it!

Wow. This puzzle was super hard, Required lots of scanning and numerical analysis. I'm glad I was able to solve it.

Even better than the first one. A lot more challenging too, but I don't mind a good challenge from time to time. Thank you for the puzzles!

Beautiful and so fun to solve. Such a clever idea and executed so well. The variety and synergy of the lines is incredible. Difficult, but once you figure out a strategy it's challenging but manageable.

Well that is certainly not what I expected the break-in to be! :D A more than worthy sequel to the first.
-------
Thanks a lot, DiMono! I am honored. Unfortunately, I had (and still have) no idea how to telegraph the break-in properly.

Truly great puzzle - I was solving while distracted and it took me a while to work through the logic. Once I saw what was going it was a pretty tough puzzle, but solved really nicely with fresh things to think about at each stage,.

That was a brutal and crazy break-in and it didn't stop after that. I did so many gorgeous deductions to solve the puzzle! I loved the logic around the lines in boxes 4 and 7 a lot! Thanks for sharing this amazing puzzle Phistomefel !
-------
Reading this, I am very glad that I redesigned the break-in to make it more accessible. And it's great to hear that the puzzle was to your liking. Thanks! :)

The break-in was too difficult, but then the loop made me insane. Very nice!
-------
Glad you enjoyed the puzzle anyway. ^^;

Has to be this hard???
-------
No, it didn't have to be this hard. I just had a few pieces of logic I wanted to incorporate into the puzzle and it turned out this way.

Brilliant, but very hard. The logic around the 3-cell lines in row 6 and column 4 was challenging and beautiful when I got to it. Somehow I made it through - very glad I put in the effort.
-------
Thank you, Fool on the Hill (by the way a very lovely book). The step you described came very naturally to life and I was glad with how it turned out.

Stunning, intricate, challenging and engaging till the very end! The logic involved around box 1 and 2 was magical to witness, but the puzzle didn't really let it loose till the very end of the solve. Plenty of fresh and wonderful deductions throughout! ;)
-------
Thank you, Playmaker! I was quite astounded for the logic these lines allow for and I am glad you enjoyed it.

Thank you so much for wonderful feedback, everyone!

@TotallyNormalCat: I'm glad you liked this piece of logic, since I was particularly happy when I found it and got it working. :)

Fully delivering on the promise of the first puzzle. Beautiful fresh deductions in here!

Amazing puzzle, I especially liked the logic around boxes 1,2 + the loop clue :)

Thank you so much for the kind words, Jesper and Piatato! I am glad you enjoyed the logical variety of the puzzle.

This constraint keeps fascinating me a lot! Thanks for the tough, but very interesting and nice puzzle :-)

Very nice! A lot of cool deductions, quite varied logic. Much more challenging than the first puzzle, in my view.
