Beautiful puzzle, thanks for sharing. Having struggled with the original ”Double Negative” this felt much easier, maybe I’ve learned something

@Onkel_Dagobert: All possible black dots are given, in your solution there should be a black dot in row 6, but there isn't.

Love how this negative constraint works, once you get the hang of it the puzzle isnt’t that hard. I would say 2 stars out of 5 for difficulty. Thanks for setting, really enjoyed it!
