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. :-)

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. ;).
