Confetti Sums Sudoku
Apply classic sudoku rules.
In all cases where the sum of two horizontally or vertically neighbouring digits is A, B or C, a white, grey or black circle is given. A, B and C are different and finding their values is part of the puzzle.
Inspiration for this type comes from stephane.bura.

Rather tough at the beginning, but then it's fun to finish. Thanks, Richard, for another interesting variant !

Klasse!
Am Anfang sieht es so aus, als ob das niemals aufgehen könnte.
Dann konnte ich Stück für Stück die ersten Ziffern reinschreiben.
Zuletzt folgten die restlichen Ziffern wie ein Schwall - und zack, war es gelöst. :-)

I am a bit surprised that the difficulty is at four stars. After a long range of three star puzzles, I had in mind to make one that is a bit easier. So don't be scared off by the difficulty, it is a pretty straight forward solve! :-)
