Bond's eX Villain sing twice...
Regeln:
⚪ Normal Sudoku rules apply.
⚪ Anti-XV: Digits in cells sharing an edge must not sum to 10 or 5.
⚪ German Whispers: Adjacent digits on a green line differ by at least 5.
⚪ REM-rule: Two corners of the grid contain the digit 3.
⚪ Ratio Pairs: A black dot indicates a place, where one digit is double the other. Not all dots are necessarily shown. Fun fact: The black dots are not needed for uniqueness, but I think, it's hard enough in this version. :-)

Solution code: row 7

In contrary to what Onkel Dagobert said:
I however struggled quite a bit with box 7 and its related digits in B-1,4,8&9.
The first was indeed as obvious as a given digit;
As soon as I knew what's high and what's low on the double-0 whispers I thought that indeed this would be a quick solve.
BUT then I got stuck for quite a bit as the anti-XV ran out of fuel.
Box 7 still crowded with options at that point, slowly chipping away single options... then when I got cleaned up a bit and stared at it not knowing what to do next I saw box4
oh what a beautiful rescue that was all I needed to have the rest fall into place.
Enjoyed that solve a LOT; thanks for sharing the puzzle!

Excellent puzzle, thank you for sharing. Regarding the difficulty: 31 minutes. Honestly, I am not good at sudoku at all, and anything over *** usually gives me headaches, but this one… I don‘t know. The first digit was completely obvious to me, and should be to any solver with basic knowledge, and things kept flowing from there. I did rely on the dots though.

Very nice but very tough too, the negative XV constraint was very tough indeed.

Very interesting early break; would put it more in the 3-star difficulty range. The ending was a bit biofacation-y for me, so I am assuming I may have missed a more elegant finish. Overall, cool puzzle.

olima: Thank you for your comment. I've had many versions of this puzzle, also without the double-3-in-the-corner-restriction and without the green 7-line poking into column 6 leading to a unique solution by two different dots in box 6, but this was even quadfurcational. ;).
