Cryptic Kropki Sudoku

(Eingestellt am 25. Juli 2020, 22:01 Uhr von Greg)

Es gelten die normalen Sudoku-Regeln.
Darüber hinaus werden Hinweise auf Unterschiede und Verhältnisse gegeben:

Benachbarte Zellen, deren Ziffern ein Vielfaches voneinander sind, werden mit einem schwarzen Kreis markiert, dessen Verhältnis innerhalb des Kreises liegt. (Ein schwarzer Kreis mit einer 5 bedeutet z.B., dass eine Zelle 5 mal größer ist als die andere).
Benachbarte Zellen, deren Ziffern sich um einen bestimmten Betrag unterscheiden, werden durch einen weißen Kreis gekennzeichnet, dessen Differenz innerhalb des Kreises liegt. (Ein weißer Kreis mit einer 5 bedeutet z.B., dass eine Zelle 5 mehr als die andere hinzugefügt wird).

Es wurden nicht alle möglichen weißen und schwarzen Kreise angegeben.

Die Zahlen wurden durch die Buchstaben A-J (ohne I) ersetzt, die die Zahlen 1-9 darstellen. Keine Zahl wird durch mehr als einen Buchstaben repräsentiert.

Das Rätsel kann gespielt werden online

Lösungscode: Zeile 1, Spalte 7

That was a tough one, and enjoyed solving it. Thanks, Greg, for a new variant.

Hi Greg, Solved the problem, was entering the wrong code :P

I liked the solve path, some very nice logic to get by. Every digit discovery was just exhausting and once found was exhilarating. Very beautiful! I love Kropki Sudokus, so this was icing on the cake for my liking.

The puzzle definitely has a unique solution, please double check you're writing the solution code correctly.
Alternatively, if you solved it with penpa you should be able to make a link with the share button and you could post your puzzle answer as a hidden comment for me to check?

Hi, I have solved the puzzle, but when I try to submit the solution code, the site complains that the code is wrong. I haven been trying to figure out what is wrong with my solve, but it seems to satisfy all the properties.

I tried this yesterday, but made a bad assumption near the start of the puzzle (though I still learnt quite a bit from that failure). I'm glad I had another go today. A very nice puzzle and with enjoyable logic! :-)

@Richard Only a hundred and forty or so to go now ;)
@Mody Danke!

Ich habe lange gebraucht, aber es hat mir sehr gut gefallen

@Greg: well, I didn’t count them, it’s just a number that poppep up first. :-)

@Luigi Thanks for the feedback!
@Richard Oh wow haha that's a daunting number of puzzles to get through. And I definitely don't want to be the reason for delaying more of your variants... :)
@SudokuExplorer Yeah I think on top of the number of puzzles posted, I also posted on a particularly busy day, and like you say for people not familiar with Kropki it might look like too long a puzzle to get through if they want to do all of them.
However regarding beginners Kropki, that already exists on the portal! ID: 00002W leads to Susie's Kropki Beginner puzzles.
If you are interested in trying this puzzle though feel free to leave a hidden comment and I can give you some hints on what to look for.

@Greg I'm fairly new to variant sudokus and have never heard of Kropki (or in general many other puzzle types). Maybe you could make a mini version (say a 6x6 version that still has interesting logic) for beginners who might be interested in trying a new variant. If they enjoy it, then you can provide a link to this one and they may give it a try.

@Greg I think this will be an ongoing problem for other setters, given how many puzzles are posted per day. One of my favourite creations (id=0003UA) only has four solves despite some symmetry that could potentially help solve it. Another recent puzzle I solved (Rook sudoku id=0003XE) only has three solves but has some very nice logic.

I am very fond of kropki and kropki like sudokus. And cryptic sudokus as well. And sudokus in general.
Apart from that it looks appealing
So it is definitely on my list of puzzles I want to try. Unfortunately there are 146 other puzzles on that list as well. And I want to write some variants myself too. Help!

But: I will definitely solve this one. Promise!

Indeed, very nice puzzle and not too difficult.

am 27. Juli 2020, 14:40 Uhr von Greg
I'm surprised at how little this has been solved as I do think it's my one of my best puzzles.
I'd really appreciate some feedback from those choosing not to solve regarding what's off-putting, whether the difficulty or the rule-set or some other reason? Thanks!

Really nice solve, the cryptic only revealed themselves slowly and the kropki were needed till almost the end.
