Credit to gUBBLOR for the new constraint, it ended up being a lot more robust and interesting than my first impression would have led me to believe!

_____

Normal sudoku rules apply. Place the digits 1-9 without repeating in each row/column/box.

Kropki - Cells separated by a white dot must be consecutive digits. Cells separated by a black dot must share a 2:1 ratio.

Equality Cages - Cages must contain an equal amount of high/low (1234 / 6789) and odd/even digits.

Shifter Lines - Digits along a shifter line must contain digits of the same polarity(high/low) and parity(even/odd). When a line crosses into a new box, exactly one of these two attributes must change.

Solve on Sudokupad

Lösungscode: Row 2 followed by Column 5, 18 digits no spaces.

Very neat execution of the constraints and there're also some funny aha moments in here, thanks for the great fun! :)

Now that was one of those puzzles that looked completely unsolvable until I made a few meta discoveries. Clever setting.

Rules clarification

That was a great puzzle! The break-in was a little "if you know, you know" and it took me a moment to wrap my head around the shifter lines, but it was never too hard or frustrating.

One small point about the rules though: someone else has pointed it out already, but mentioning the polarity/parity on the shifter lines was a little confusing. I didn't really know what you meant by that and assumed it was basically the same as high/low and odd/even (which is how you explained the equality cages). Turns out that was right, but it can be a little unclear to a solver who's not familiar with the terminology. You might want to clarify that in the rules.

The rules are a little unclear. Equality Cages refer to high/low and odd/even digits while shifter lines refer to polarity and parity...

These two rules are referring to the same things, polarity is high/low and parity is odd/even. I would suggest changing the rules to just use the odd/even and high/low terms and drop the polarity/parity terms.
