Parity Poopers
(Eingestellt am 29. Februar 2024, 12:59 Uhr von aleph-0)
Normal Sudoku rules apply.
Cells separated by a King's move in chess (horizontal/vertical/diagonal neighbours) cannot have the same digit. Grey circles indicate an odd digit, grey squares indicate an even digit. Clued cells and cells containing digits that equal their box number are Parity Poopers. Note that clued cells may contain the box number.
A Parity Pooper containing the digit N has exactly N-1 digits of opposite parity (odd/even) in the surrounding cells (by King's move).
Lösungscode: Row 5

The wording of the rules put me on the wrong leg here. It's about 'and'. For me it was confusing that a clued cell could be also a box-number cell. I ruled out a 5 in R6C4 first, which led to a contradiction. I would add a sentence 'Clued cells may also contain the box number' or similar.
Furthermore I had fun with this variant, so thanks!
Update: Thanks for solving, sorry for any confusion, I have added a clarification to the rules.

Really nice, deserves more solves!
PS: thx for putting the anti-king constraint into the link. I nearly missed that rule tho.
