Dieses Rätsel ist eine Mischung aus einem Kurotto und einem Fortress-Sudoku.

Hier die Regeln:
  1. Es gelten die üblichen Sudokuregeln.
  2. Einige Felder müssen gefärbt werden. Die Zahl in einem eingekreisten Feld stellt die Gesamtzahl der gefärbten Zellen in zusammenhängenden Gruppen dar, die eine Kante mit dieser Zahl teilen. Eingekreiste Felder dürfen nicht gefärbt werden.
  3. Gefärbte Felder gelten als Fortress-Felder, d.h. jede Zahl in einem gefärbten Feld muss größer sein als jede Zahl in einem benachbarten ungefärbten Feld.
Zur Illustration findet ihr hier ein Beispiel auf einem 6x6-Gitter:

Hier findet ihr einen Link zum Beispiel.

Auch das Rätsel ist online über Penpa Plus verfügbar. Viel Spaß beim Lösen!

Lösungscode: Alle Zahlen in gefärbten Zellen in den Zeilen 1, 5 und 9.

A truly awesome puzzle

I'm a latecomer in this community, so I discover these "old" puzzles little by little. It feels like tasting chocolates out of a big chocolate box, like Forrest Gump said. This one tasted rather good, a "Grand Cru" that took me a while but was greatly rewarding in the end ! Thanks.

I had to start over 2 times. At the end yelled "freedom!" so hard my cat got scared.

Its amazing, was not extremely hard, but it was brilliant how the puzzle kept fighting back until the very end.

Beim zweiten Versuch ging es sehr schön logisch durch. Hat super viel Spaß gemacht. Tolle Rätselidee!

I really like puzzles that left a bit behind classic sudoku, especially when it's for so smooth logic like throughout this one.
Great job, thanks for sharing.

Really cool ruleset, didn't felt too hard, but the final few eliminations really took me ages to spot, felt great after that though, especially since this is the first puzzle of yours I managed to solve. Thank you for the joy you bring to all of us, maestro!

Seemed very hard at first, but became quite smooth and nice quickly. Another home run from Phistomefel.

After around two months of following CTC daily, I've decided to register here and try many yet to be shared puzzles, and what a way to start my journey :) First puzzle down, phenomenal job Phistomefel!

Großartiges Rätzel!

What a fantastic puzzle. Definitely finishes more difficult than it begins. Thanks for setting it.

My solution for the 6x6 was the same as yours, using dark blue sudoku numbers. https://logic-masters.de/Dateien/index.php?id=000AIF When I re-opened it just now and entered it again it worked. Very strange.

@DiMono: That is odd. I just checked the 6x6 example in Penpa Plus, put in the solution given on the right hand side and the answer check worked for me.

Maybe I was a bit careless and the example does not have a unique solution. Could you maybe post a link to your solution?

Answer check on the 6x6 example doesn't seem to be working

Wow! Thank you very much everyone for giving the puzzle a go, for the wonderful feedback and for the amazing rating. :)

Wow! What a great puzzle, had much fun solving it, thank you Phistomefel!

My experience was similar to Magnus and Mark’s experiences. At the beginning I thought 4 stars difficulty might be an overrating but at the end I think 4 stars is fair.

Very nice! I had a similar experience to Magnus: the start was mostly an introduction, after which more elaborate logic was required.

Gotta hurry before Simon gets to it!

We should run a bet on every Phistomefel's puzzle on how long it takes to be featured on CTC.

Lovely and fantastic puzzle! The setup of the circles is excellent and that ending is just miraculous, it really made me think at one point I might have broken the puzzle. Beautiful as always ;)

Regellücke gefüllt. Vielen Dank an Dandelo für den Hinweis!

Great puzzle! Impeccable logic throughout. At first it seemed easier to me than four stars, but the ending required some careful thought. Thank you Phistomefel!

Ich denke, dass eingekreiste Felder nicht gefärbt werden dürfen. Aber die Regeln verbieten das nicht.

Very fun puzzle to solve, goes very smoothly!
