Araf Killer Sudoku
(Eingestellt am 28. Juli 2020, 09:00 Uhr von Phistomefel)
Zu den Regeln:
- Es gelten die üblichen Sudoku-Regeln.
- Das Gitter muss in verschiedene Gebiete zerlegt werden. Dabei wird jede Zelle genau einem Gebiet zugeordnet.
- Jedes Gebiet enthält genau zwei Hinweiszahlen.
- Die Summe aller Ziffern in einem Gebiet liegt zwischen den beiden Hinweiszahlen, darf sie aber nicht erreichen. Sind die Hinweiszahlen für ein Gebiet z.B. 21 und 24, beträgt die Summe der Ziffern im Gebiet 22 oder 23.
- In einem Gebiet dürfen sich keine Ziffern wiederholen.
Wenn ihr etwas über Lösungsstrategien für Araf-Rätsel (die sich auch für dieses Rätsel verwenden lassen) erfahren wollt, kann ich euch das CtC-Video über Murat Can Tontas Araf-Rätsel empfehlen.
Nun zum Rätsel. Das gibt es auch online über Penpa. Viel Spaß beim Lösen!
Lösungscode: 5. und 8. Zeile

lovely puzzle. it's been over half a year since your last hybrid puzzle; don't you think it's time for a new one? :)

I got confused a bit at first because I watched the Araf video first and I kept trying to make this work the same way which, of course, it doesn't. Once I wrapped my head around the differences, I followed the path fairly smoothly and easily, and I had a lot of fun! I hope to see more like this!

Fantastic puzzle! A very narrow solution path with many surprising and rewarding deductions. It was challenging until the very end.

Very nice constraint and puzzle !! Loved the last bit which requires a careful region exam to get the last cages !

Toll, toll, toll! Und gar nicht so schwierig, wie die Wertung vermuten lässt. Das hat sensationell viel Spaß gemacht. :)

This puzzle is ridiculously nice! Not too hard because the logic flows so nicely, but always beautiful. Thank you for setting these kind of puzzles, Phistomefel!

Absolutely incredible and amazing puzzle. Brutally difficult logic.
It felt like a triumph just to be able to place the first digit into the grid.
I registered just to leave a comment and rating.
@Philip: Thank you very much for your feedback and for registering only for this puzzle. That is so cool! :)

Amazing puzzle!
@nordloc: Thanks for your persistence and the nice comment!

Insane! What an ending!

Really hard, but really nice puzzle. There was one time I wasn't able to figure out a logical next step and made a quess (which turned out true). I'm looking forward to CtC video on this puzzle to see what I failed to spot and what the right way to solve it is.

Thank you everyone for the amazing feedback. I'm very glad you liked it.

Several times during the solve I thought: That's it - this is how far I can go. There's simply not enough information for me, who's never heard of Araf before, to proceed. But then I kept playing a bit more and suddenly - unexpectedly - new insight came to light that allowed me to venture on. It was quite a roller coaster ride.

This puzzle is HEAVENLY!!! What an outstanding construction. I loved how you had to keep alternating the focus on the arithmetic and developing the regions to proceed the solve. Absolutely amazing!
PS. I don't think 5 stars are enough to grade either the difficulty or the beauty of this puzzle! This one is beyond that.

Brilliant. Really liked the logic towards the end. Well done.
