Thermohaline (Nurikabe Thermo Sudoku)
(Eingestellt am 11. Oktober 2022, 09:00 Uhr von Agent)
Was wäre, wenn jede Nurikabe-Insel ihr eigenes Sudoku-Thermometer wäre? Nachdem ich mehrere Wochen lang mit Nurikabe-Hybriden experimentiert hatte, stellte ich fest, dass sich die meisten meiner Ideen um Pseudo-Killer-Käfige und/oder Richtungshinweise drehten. Was mir an Thermoskannen gefallen hat, ist, dass sie eine starke Einschränkung der Ziffernplatzierung bieten und die möglichen Pfade entlang einer Thermoskanne zu einer zusätzlichen Ebene geometrischer Logik führen. Ich hoffe, Sie werden es genießen! Ich empfehle, zuerst das Beispielpuzzle auszuprobieren, wenn Sie Zweifel bezüglich des Regelsatzes haben.
Regeln
- Es gelten die normalen Sudoku-Regeln.
- Schattieren Sie einige Zellen im Raster so, dass alle schattierten Zellen orthogonal verbunden sind. Kein 2x2-Bereich kann vollständig schattiert werden.
- Gruppen orthogonal verbundener nicht schattierter Zellen bilden Inseln, die sich nicht orthogonal berühren, aber diagonal berühren können.
- Ziffern entlang eines Thermos müssen von der Birne aus zunehmen.
- Jede Insel muss genau einen großen Kreis (Birne) und einen kleinen Kreis (Spitze) enthalten. Alle Kreise müssen unschattiert sein.
- Auf jeder Insel muss es möglich sein, einen nicht verzweigten Thermo zu zeichnen, der jede Zelle auf der Insel besucht, von der Birne bis zur Spitze. Thermos kann sich orthogonal oder diagonal bewegen. Eine Thermo kann sich selbst kreuzen.

Very cool!

Excellent puzzle ! Some hard deduction in the midsolve to get rid of some ambiguity, but very enjoyable all the way. Thanks
-- Thank you @Christounet! Admittedly this puzzle and especially the mid-solve is a bit evil.

Masterpiece! Very tricky yet beautiful crossover. Almost give up at the middle box.
-- Thanks @peacherwu2! I'm really glad to hear this.

Great stuff. Like some others, I failed to spot some configurations of thermos and broke the puzzle twice. Agent kindly gave me a hint which enabled me to solve it. Very neat idea which messes with your head!
-- Thank you @StephenR! Seems like it's very easy to overlook cases with this puzzle, but I'm glad you got there in the end!

I was a bit confused by the ruleset initially, but it ended up playing out quite intuitively. The interactions between islands were really fun to discover, and there was a lot of nice geometrical logic. Thanks Agent :)
-- Thank you @Xendari for the kind feedback! I see that you solved several of my puzzles lately, so thanks for that as well. I hope you had a great time with them!

That was very tricky and took me several goes, as I kept breaking it with a wrong assumption on a thermo branch
- had to leave it a few days to refresh, and today saw the option I'd incorrectly eliminated/missed
-- Sorry about that, I admit that the geometry of thermos is a bit evil. But I'm glad that you persevered and were able to solve it in the end!

Very nice puzzle. Crossing thermos definitely upped the difficulty but worth it.
-- Thank you @bansalsaab! I agree that the geometry of thermos is quite tricky in this puzzle.

Great puzzle, recommend for CtC!
At first I didn't understand how a thermo could cross itself, but then I learned. :D I think showing a self-crossing thermo in the example puzzle would be very helpful.
I made a fatal mistake (unrelated to self-crossing) and had to restart. But even with that, the puzzle is only 4 difficulty for me.
-- Thank you @henrypijames! That's still harder than most puzzles ;) You're not the first person to point out that the possibility of crossing thermos was confusing, I'll keep this in mind.

Very cool concept, and some really nice logic in this puzzle! At times quite difficult.
-- Thank you @MagnusJosefsson! It's probably one of my hardest puzzles so far, and very easy to miss some possibilities.

Excellent!
-- Thank you @Vebby!

Superb puzzle, really interesting how the shape of the islands evolved and how the thermo's where forced. Thank you so much!
-- Thank you @Snookerfan, glad to hear that you enjoyed the interactions between the rules!
