I had a lot of fun solving this puzzle from PetLov and wondered how far the use of the negative constraint could be extended. This is the result.
Squares of Parity Sudoku
Apply classic sudoku rules.
A digit in a square correctly indicates the number of even digits and/or the number of odd digits in the horizontal and vertical adjacent cells. All possible squares are given. A digit in a circle indicates the sum of the digits in two or more of the horizontal or vertical adjacent cells. Not all possible circles are given.

'und/oder' muss heißen 'oder', oder?

Reply: und/and is also possible in case of 2 odds and 2 evens, or 1 odd and 1 even in a corner.

Nice one! The difficulty really ramps up in the mid-solve.
