Ich konnte ziemlich viele Ziffern mit Logik ermitteln, habe dann einmal geraten und Glück gehabt. Auf jeden Fall ein ganz tolles Rätsel!

@flaemmchen: Da bist du nicht die erste. Und auch sicher nicht die letzte...

@Dandelo: Ja 3-6 ist einer Stelle falsch, obwohl ich da zig Mal draufgeschaut hab'. Manchmal ist man halt blind ... Danke :-))

@flaemmchen: Ist bis auf die 2-Potenzen falsch, vermutlich ist irgendwo doch eine verbotene Beziehung drin (3-6 meistens)

Thanks for the hint, I'll add a hidden comment this evening, when I'm back from work, and have access to my solution path.

@shinya: If you have a solving path, you also can share it via a hidden comment. Then only those can read it who already have solved.

@both: You may write questions to the author in a hidden comment. Then the author can edit this comment attaching the answer. After that only the author and you can read it, and those of course who already have solved

If you have a good problem solving idea, can you give me a E-mail？ My email is 2088426@qq.com, thank you very much!

I have, what appears to be a correct solution, except it's apparently not. I can't figure out what's wrong though.

EDIT Found a bad knight's move, which must mean something I thought had to be correct near the very beginning was probably wrong because it seemed logical after that.

@cdwg2000
Just wanted to give you a hint, and just saw you solved it. Apologies for not being faster :-(

Crazy try and error.

Beautiful and surprising. In the beginning I couldn't believe it was unique, but ...

In the end I needed a little bit T&E, but I think I know, what I've missed.

This question is very difficult. If possible, can you provide clues to the problem? Thank you!

Well, I'm new in here (it's my first ever sudoku), so I do not know by what standards you would call a solution logical.
But there is only one solution, and you can step by step exclude candidates from cells to identify the correct numbers.

Does this Sudoku have a logical solution?
