Normal sudoku rules apply. Neighboring digits marked with a black Kropki dot have a 2 to 1 ratio. All *black* dots have been given - for black dots the negative constraint is in force. Neighboring digits marked with a white Kropki dot are consecutive. Not all *white* dots are given. No negative constraint for white dots. Note: 1 and 2 are allowed to be adjacent, even without any dot. I think this puzzle is 1.5 stars out of 5 for difficulty for many solvers. As always, comments welcome. Thanks!

I kept thinking that ALL whites dots were given and failed many times, but I've finally solved it!
Thanks!
*** Oooohhh.... I tried to be clear in the instructions. :-( But I'm glad you finally made it!

Thanks for this puzzle. I actually follow you and was surprised to see you had posted a new puzzle!
I had a bit of difficulty near the end trying to disambigute between two certain odd numbers. Not sure what I missed, but I eventually solved the puzzle by seeing which one of the numbers would break it.
** Thanks so much - I am touched. Yeah I took a break because I couldn't think of any new ideas! But now with all of the new constraints, you should see new puzzles coming from me.
I'm not sure what happened for you at the end, but I'm glad you could work thru it!

Nice and easy. Creative usage of the black kropki dots and their negative constraint.
*** Thanks for the solve.
