Normal Sudoku rules apply.
In every 3x3 block, the fields of each color (except for white) contain either all even or all odd digits.
Kropki: white dots link cells with consecutive digits, black dots link cells with a ratio of 1:2; not all possible dots are given).

Much love to the setter, thanks for great puzzle :)
What a mind bender. Maybe I should have chosen different colors for odd/even, rather than using blue/orange, which I normally use to color high/low. Quite a few times I caught my self thinking "Oh this cell is orange, therefore it must be high" wrong, wrong, bad, bad brain :)
