The idea comes fromKlomp's puzzle
Standard sudoku rules applies. Fill the grid with numbers from 1 to 9 so each digit occurs exactly once in every row, column and 3x3 box.
The box number in its box would turn all different parity cells that are in its box and in its 8 surrounding cells into the box number.
Normal kropki rules applies. 12 can be black or white. The dots treat the turned as the turned.
All possible dots are given.
Let's hope this clear the rule. All the digits in orange square turned into 2, other digit won't be turned.
This puzzle is made by Old Miles from China. A more detail rule and series intro can be found in my previous puzzle. And as always, I would give my opinion on this series at the end.
Some back story on this one. This puzzle has a fake break in point which can only be solved at about halfway-solve. And youay found the layout quite different from the 6X6 ones, mainly for the isolated parity box (assumed you solved my previous one). You might found it amusing.
Also, I really want to know how many times you break the puzzle before solving it. Of course you can be super careful about your choice, but I found most of my fun with the breaking point.
Solution code: All the unturned row, then column (9n digits)

Also nur die benachbarten (diagonal/orthoganal) Digits sind betroffen? Warum dann dieser Text ?
and in its 8 surrounding cells into the box number.
Das geht doch nur, wenn die Ziffer jeweils in Feld 5 steht?
***bigger:Ja, nur die benachbarten Ziffern sind betroffen. Aber die benachbarten Ziffern müssen eine andere Parität als die Box-Nummer haben. Und die benachbarten Ziffern müssen sich im selben Feld mit der Feldnummer begeben.
auch, ich füge ein Beispiel hinzu, hoffen, dass es klar genug ist, um verstanden zu werden

@SKORP The rule is a bit complicated, but it does work once you get your mind around it. You're a little bit wrong. The four in Box 4 would affect any of the ODD digits that are NEXT TO IT orthogonally / diagonally AND still in box 4. This causes it to act differently with regard to kropki dots. It maintains it's personality with regard to sudoku rules. It's possible that, if that four was in the corner, that an odd digit in the opposite corner would not be affected. Also, numbers in other boxes won't be influenced by a digit.
I found it useful to use corner pencil marks and/or shading to indicate digits that ACTED as one digit.
When you are finished, there will be some row(s) and column(s) that never had any affected digits. The solution code is to type those row(s) and column(s) in. But how many row(s) and column(s) is left vague for the solver to determine.

ich glaube., jetzt habe ich die Regeln verstanden
z.B in Box 4 werden alle 1,3,5,7,9 als 4 angesehen?
***bigger:Nicht ganz richtig. 13579 muss in Kasten 4 und orthogonal oder diagonal mit 4 verbunden sein, dann können sie auf 4 umgestellt werden (ich kann nicht Deutsch sprechen, also kann ich nicht sagen, ob das funktioniert)

For example: in BOX1, all even numbers adjacent to number 1 (orthogonal or diagonal) will directly become number 1 to participate in the rule calculation when performing the black and white dot rule operation; in BOX2, all odd numbers adjacent to the number 2 (orthogonal or diagonal) will be executed in the black and white dot rule operation.

Please explain the rules better. Right now it reads as if a 2 in box 2 would turn 1, 3, 5, 7, 8, and 9 in that box into 2s. That doesn't sound plausible.
***Bigger:please read the rules more careful.The box number in its box would turn all different parity cells that are in its box and in its 8 surrounding cells into the box number.
Only when 13579 is in box 2 and in 2's 8 surrounding cells can be turned into 2
