The variant for November 14, 2019 I think has two solutions. I can't see any way to tell where the highlighted 8s and 9s should go.

Dear JediKreena!

There is a problem with the negative rule. In your case you are missing there black dots by number 8 which is next to two cells with number 4.
If I highlight here the rules you can see it there:

rules
Place a digit from 1 to 9 into each of the empty squares so that each digit appears exactly once in each of the rows, columns, 3x3 box. The white dots indicate all the adjacent/neighbouring cells in which the difference between the two cells is 1. The black dots indicate all the adjacent cells in which one digit is the double of the other one. The dot between two cells with digits 1 and 2 has any of these two dots.
