It's a Non-Factor
(Eingestellt am 26. Oktober 2023, 09:24 Uhr von SSG)
Killer: Digits in cages may not repeat and must sum to the total in the top left corner.
Anti-Factor Lines: A line may contain no digit that is a multiple or factor of its length other than 1, and the digits along a line must sum to a multiple of its length. Digits may repeat along a line if allowed by the other rules.
Lösungscode: Column 1 + Column 8 (18 digits)

I have never imagined applying Chinese remainder Theorem to sudoku! It is an amazing puzzle!

@bansalaab - puzzle is on page 4 now, so hopefully I can post a clue that is a bit of a spoiler. set theory is a good idea, but not the ring. think about top left vs bottom right, and see what you can force to be equal...

Couple of easy deductions to think you're getting somewhere, then an absolutely astounding break-in, then flowed nicely the rest of the way. Fantastic puzzle.

Absolutely delightful!

I ve been trying to use set theory or the "ring" for couple of hrs but cant figure out the breakin. Need to look elsewhere:-(

An amazing break-in and very very smooth thereafter. All in all an extremely satisfying solve. This is the kind of puzzle Simon would love explaining on CtC. It had all the elements - the moduli, the oft-explained theorem, the works… Thanks a lot for sharing.

Great start. Very satisfying till the end.
Congrats SSG.

Very clever use of the Anti-Factor constraints! Thanks for exploring what they are capable of
