Shifter Dots
Dieses Rätsel ist von gUBBLOR inspiriert.
Solve online in Sudokupad.
Wie alle meine Sudoku-Varianten kann dieses Rätsel rein logisch gelöst werden. Raten ist nicht erforderlich, und es sind auch keine ausgefeilten Lösungstechniken nötig; es genügen einfache Sudoku-Schritte und natürlich die Logik, die diese spezielle Variante zu bieten hat. Falls du diese Logik nicht findest oder nicht weiterkommst, kannst du in den Kommentaren unter diesem Rätsel nach einem Tip fragen, und ich werde dir gerne helfen.
Verwende die üblichen Sudoku-Regeln.
Ziffern auf verschiedenen Seiten eines Punktes müssen immer entweder die gleiche Parität (gerade {2,4,6,8}/ungerade {1,3,7,9}], oder die gleiche Polarität (hoch {6,7,8,9}/niedrig {1,2,3,4}) haben. Niemals keins von beidem, niemals beides. Die Ziffer 5 darf nicht neben einem Punkt stehen. Es sind nicht unbedingt alle möglichen Punkte gegeben.
Erlaubt: 8,4 (beide gerade; eine hoch, eine niedrig), 8,9 (beide hoch; eine gerade, eine ungerade).
Nicht erlaubt: 7,2 oder 2,4.
Lösungscode: Spalte 1.

I confused myself for so long by thinking that there were 4 kinds of polarity here, rather than just 2.
The coloring trick was very handy, to keep track of which rows, columns, and boxes had how many of each!

Started this puzzle a few times and each time I got stuck. The solution came by thinking less and looking more at what is not possible. After that I had solved it fairly quickly.
Thanks for the nice puzzle.

Oh! I tried to do this in the morning - and failed in desperation. I was sure I broke the puzzle… But now I got it! And loved how the ruleset works. Thank you very much, Richard, for creating and sharing another beautiful puzzle. And don’t worry about the typo.

Started with my usual technique of checking every option then got bogged down.
I know 'Sudoku Sleuth' on YouTube explains Shifter Dots with two colours but I've never taken it in.
Found one of his later videos on Shifter dots to learn the skill.
Boy is it simple to just colour and not have to check the relationships.

Reply: That sounds indeed like an easy way to approach!
Would love to see how that works for this specific puzzle. :)
I hardly watch YouTube channels were puzzles or sudokus are solved; I simply don't have time for that...

Smooth puzzle! I found the variant to be a bit confusing at first, so maybe it was actually good that I got to practice with a couple of false starts :)

This puzzle was tested with grey dots. Only this morning I found out what color to use for the dots and made the link in Sudokupad app + image in a hurry before work. But hurry is never good.
Now everything shoud work. Once more my sincere apologies... :(

Edit: thank you for fixing, very nice puzzle :)
