- Kropki: Cells connected by a white circle contain consecutive digits. Cells connected by a black circle contain digits with a 1:2 ratio. Not all possible circles are given.
- Killer cages: In cages, digits sum to the number in the top left corner of the cage. Digits do not repeat within a cage.
- Quadruples: Digits in a circle must appear at least once in the four surrounding cells.

Author's note (contains some, though not too helpful, hints for solving the puzzle):
This one's a two-parter called "Emulsion" cause the two sets don't mix :)
I'm "gespannt wie ein Flitzbogen" what the difficulty consensus for this puzzle is going to be. I feel like it is harder than The Devil Eludes Death, but easier than Hidden Nonidentity. So a 3.5? I'd be curious to hear your thoughts. Starting it off on a 3 to give people hope :P
I hope you enjoy(ed)!
Solution code: Row 9 from left to right (9 digits).

Thank you for the kind words and feedback everyone! I'm glad you enjoyed :)
As a note: no bifurcation/brute force is necessary in the second stage. Some coloring might help though.

Enjoyed the puzzle a bit of hard bifurcation towards the end...wonder if I missed something. Thanks!

I was going to comment on the binary nature of this puzzle, but i see that the setter has already done so.
Definitely not a beginner puzzle, but i think a difficulty of 3 is fair. Intermediate solvers will be challenged, but not stumped. The first part applies a well-known principle, and then you are close enough to the end that you can use brute force to finish.
