Three little burgers (Anti-king/anti-knight killer sudoku)

(Eingestellt am 24. Juni 2024, 23:36 Uhr von sujoyku)

In letzter Zeit habe ich ein paar anspruchsvollere Rätsel eingestellt und dachte, es ist mal wieder an der Zeit für ein zugänglicheres Exemplar. Dies ist ein Killer-Sudoku, der sowohl eine Anti-king als auch eine Anti-knight-Beschränkung aufweist. Der Einstieg hat eine Idee, die mir sehr gefallen hat. Die Schwierigkeit schätze ich auf 1.5 Sterne (vielleicht 2 Sterne, wenn man noch nicht so viel Erfahrung mit den geometrischen Bedingungen hat). Schreibt gerne in den Kommentaren, wie es Euch gefallen hat. Ich wünsche Euch viel Spaß beim Lösen!

- Es gelten die normalen Sudoku-Regeln, d.h. jede Reihe, Spalte und 3x3-Region muss jede der Ziffern von 1 bis 9 genau einmal enthalten.

- Anti-king/anti-knight: Zellen, die einen Königs- oder Springerzug (im Schach) voneinander entfernt sind, dürfen keine identischen Ziffern enthalten.

- Killer-Käfige: Ziffern in einem Käfig ergeben in der Summe den oben links angegebenen Wert.

Hier kann das Rätsel online gelöst werden:

Solve on f-puzzles

Solve on CtC

Lösungscode: Spalte 1 von oben nach unten (9 Ziffern insgesamt)

Took me 20 mins to figure out that break-in! Neat puzzle

**
Thank you for your comment, 9Rookienumbers! The break-in is the hardest part I guess. I am glad that you liked the puzzle.

The puzzle gets quite a bit more approachable when you realize there is an anti-king's move restriction...great puzzle! Super fun!

**
Thank you for your comment, meggen033! You are absolutely right: The anti-king constraint is crucial. I am glad you had a fun solve.
Kind regards, sujoyku

Brilliant setting. Tasty set of burgers, each one with that extra ingredient (or the lack of it...?) that made them special!

**
Thank you for your comment, Fra314! I have to admit I did not really get the joke/reference about the extra ingredient. :)
Anyhow, I am glad you liked the puzzle.
Kind regards, sujoyku

Agreed with others saying the break in took way longer than it should have. Once I wrapped my head around it, it was brilliant. And the rest of the puzzle resolved easily from there. Sort of like a 2 star break in and a 1/2 star flow. Very nice!

Thank you for the comment, Karitsu! I am glad that you liked the puzzle.

A beautiful bit of logic needed to break in, which eluded me for quite a while. Once spotted the whole puzzle flowed very smoothly.

**
Thank you for commenting, DarrenBurnett! The break-in is definitely the hardest bit of the puzzle. Glad to hear you had a smooth solve thereafter.
Kind regards, sujoyku

nice trick with the cage geometry, where ALL THREE constraints must be used together to get started.

**
Exactly, VitP, that is why I liked the set-up so much. Thank you for commenting!

Took me way longer than it should have. Interesting break in. Easy flow from there. Would rather put it at 1.5-2/5 difficulty.

Great puzzle none the less

**
Thank you for the comment and sharing your opinion on the difficulty rating, Christovaneeden! I am glad you had a nicely flowing solve.
Kind regards, sujoyku

Lovely little puzzle :) When I started solving, I particularly enjoyed the combination of knights move + kings move constraints. So this was a bit of nostalgia on top - thank you :)

**
Thank you for your kind comment, Shape! I am glad that you liked the puzzle. Funny that you mention nostalgia since I don't have too much experience in anti-king/anti-knight setting. I saw these constraints being used in this year's DSM competition (German sudoku championship). As I would like to contribute some puzzles to next year's edition, I have started to look a bit more into setting these variants.
Kind regards, sujoyku

Couldn't agree more; that break-in and this puzzle as a whole — *chef's kiss*
