---- REGELN ----
Irregular Sudoku Regeln gelten: Platziere die Ziffern 1 bis 9 genau einmal in jede Zeile, Spalte und umrandete Region.
Country-Road Parity Loop: Zeichne einen einzelnen 1-Zellen-breiten in sich geschlossenen Weg in das Gitter, welcher orthogonal benachbarte Zellen miteinander verbindet und jede Zelle maximal einmal betritt. Benachbarte Ziffern entlang des Weges besitzen unterschiedliche Parität. Beachte, der Weg kann sich selbst berühren. Außerdem muss der Weg jede umrandete Region genau einmal betreten. Wenn zwei Zellen, welche eine gemeinsame Kante besitzen, in verschiedenen Regionen liegen, so muss mindestens eine der Zellen auf dem Weg liegen.
Kreise: Ziffern in Feldern mit Kreisen geben an, wie viele Zellen in der entsprechenden Region Teil des Weges sind.

Oof. I found the sudoku part at the end to be rough. I'm still new to this irregular sudoku style, so that made it harder still.

I had a little bit of trouble with the sudoku of odd digits (I can easily place all the even digits)

I'm glad you still made it in the end and I hope it was not too much of a bother. I agree, the odds are the most complicated part of this puzzle, they involve a few steps which are trickier, in particular if one is not used to irregular Sudoku. I think it depends a bit on how lucky one is while scanning for the next weak cell(s) and unfortunately I assume that's also why some people didn't like it that much. I had a few versions of this puzzle (including one with one circle and one given less) but this one was the only one where bifurcation (or similar techniques) was not needed :)

Great puzzle! Definitely had to read the rules carefully, but lots of great loop-building logic followed by some interesting irregular Sudoku.

Haha, I had to check the rules a couple of times to realize what they did not say... This required new kind of thinking and it took some time to find a starting point, but then flowed beautifully. Well done!
