I’ll go out on a limb here and suggest that Zinker was playing on 69. Look at the pairings of 6 and 9. The solution code of row 1 is independent of the two the possible solutions. 69 takes two. So while the puzzle has two solutions, there is only one correct solution code.

Now then; there is not a negative constraint IMO. Someone could post that not all black and or white dots are given and have zero dots in the puzzle and that would be logical. Indeed in this puzzle there are multiple other cells that could have a dot but do not.

Maybe Zinker logic was the use of AND. White AND Black dots instead of white or black. Who knows. I’ll go with the 69 logic which is still lazy. Take turns. Do it right.

This is my first ever comment but I feel I have to say something. I actually quite enjoyed this puzzle and up until the last four digits, it was great. I think a 35% rating is unfair, even with the deadly pattern. Now, onto the deadly pattern - I don’t think your argument works. I think you’re implying that because not all dots are given, there could be a black dot between R6C4 and R6C5 which resolves the deadly pattern. However, you could also argue that ther are white dots between R5C5/R5C6 and R5C7/R5C8 which would resolve it the opposite way. As others have said, the fairest way to have resolved it, would’ve been to just add an extra dot. Still enjoyed it though!

It's not a Sudoku.

Welp, we can all collectively agree that the puzzle is just straight up broken, regardless of how it’s resolved (with or without the negative ‘tricks’).
I honestly think it would be better to revise the whole thing again and consider how to use the constraints better instead of just placing only one-off constraints that don’t really play some role on the rest of the solve.

I also had the same issue with the deadly pattern. There are already both black and white dots not present regardless of the resolution. You need to add one of the black or white dots that would resolve it. Or add the other missing black and white dots so that is the only source of missing ones.

die letzte Regel ergibt keinen Sinn. wie schon erwähnt wurde, ist sie bedient ohne die letzten 4 Ziffern zu lösen
vlt wäre eine andere Formulierung sinmvoller oder Erklärung, wie die negative Regel zu verstehen ist

Thanks for the hint, Redmuunk. I really don't like this kind of "trick".

The deadly pattern is resolved by the final rule, "Not all white and black electrons are given

Lovely puzzle! However, there is that unresolved bit at the end, I agree.

I also can't see how to solve the deadly pattern at the end.
Edit:
If it's the last rule resolves it then it isn't clear since that is already apparently satisfied without resolving it

Me too.

I have a deadly pattern in the end that even the negative constraint doesn't resolve.
