Modular repulsion
(Eingestellt am 28. April 2023, 19:25 Uhr von sujoyku)
- Es gelten die normalen Sudoku-Regeln.
- Nachbarschaftsbeschränkung: Orthogonal benachbarte Ziffern haben niemals eine Differenz von 3 oder 6, z.B. darf die Ziffer 1 niemals orthogonal benachbart zu einer 4 oder 7 sein. Mit anderen Worten: Die ganzen Zahlen von 1 bis 9 werden bzg. ihres Restes mod 3 in drei Gruppen eingeteilt (147, 258 und 369) und es dürfen niemals zwei Ziffern aus der selben Gruppe orthogonal benachbart sein.
- Killer-Käfige: Ziffern in einem Käfig dürfen sich nicht wiederholen und ergeben in der Summe den oben links angegebenen Wert.
Hier kann das Rätsel online gelöst werden:
Lösungscode: Reihe 5 gefolgt von Spalte 5, von links nach rechts bzw. von oben nach unten (18 Ziffern insgesamt)

Beautiful break in. After that, challenging for me. (More than a 1-star, for sure.) Thanks for an enjoyable puzzle.

I’m glad you clarified your meaning of multiple because it seemed like an implicit kropki dot of ratio 3 vs. modular arithmetic. Once I grasped that it was very clear and fun solve path

Thank you for your feedback, erik! I am glad that you had a fun solve. I thought the adjacency rule might need some clarification. Therefore I've tried to explain it in detail. It's great to hear that the rule set is comprehensible right now.

What a fun rule! The symmetry keeps it at 1* for me, I think. Thank you for sharing!

It seems most solvers agree with your assessment of the difficulty towards 1/5.
