==== RULES ====
Normal Sudoku rules apply : fill the grid with digits 1 to 9 appearing each exactly once in every row, column, and 3x3 box.
Killer Sudoku :  Cages must sum to their indicated total. Digits can not repeat in a cage.  Not all cages summing to 15 are given.
Kropki dots : Cells separated by a white dot contain consecutive digits. Cells separated by a black dot contain digits in a ratio of 1:2. Not all dots are given.
==== THANKS ====
Thanks a lot to FreakyFred, Florian Wortmann  and XeonRisq, for testing and giving feedback on the puzzle, or its first draft (harder break-in and different layout, if interested you can try it here on F-puzzles).
Solution code: Digits from Row 1 (left to right) and then from Row 4 (left to right). No space, 18 digits in total.
