Normal Sudoku rules apply, place the digits 1-9 in each row, column, and box.
German whispers: Adjacent digits on a green line must have a difference of at least 5. All German whisper lines have been given that would be vertical or horizontal. (i.e. There is a negative constraint, but this does not apply to diagonally adjacent digits.)
Ratio Pairs: Digits separated by a black dot must be in a 2:1 ratio. All black dots have been given.
This is a sequel to Heard No More,
and Heard No More 9.

Wow that was hard (for me that is)
I didn't see it and after about 30 mins staring at it yesterday, coming out empty I read the comments and thank you The Bard for pointing out the way to break in...
I then looked at it again today with that clue you gave and started tinkering and then it clicked, sheesh that was still tricky.
But eventually it gave way and the solve flowed nicely afterwards indeed, lovely puzzle, thank you again!

Wonderful puzzle. Took some time to wrap my head around power of the negative constraints.

Nice puzzle, the interaction between the two constraints, especially with the negative requirement was a good a-ha moment.

in order to qualify for level 2, there needs to be something to "bite on".
- can you do anything with 5s ? no
- can you do anything with 4/6s ? no
- can you do anything with high/low colouring ? no
- can you identify ANY of the kropki pairs ? no
- can you even LIMIT any of the kropki pairs ? no
and the negative constraints aren't even worth mentioning.
~~
I can't be certain, but given your list you may have overlooked the most important constraint that is critical for this puzzle, the negative GW constraint. Without that this puzzle is not possible.
I do agree that the break in is a bit tricky making it a little high for a 2 star, but after the break in it is a lot easier and starts flowing.
Hope that helps.
