-Story line-

This machine is really taunting me. Not only it creates the weirdest bugs ever, it even messes up the most important thing about kropki : dots ! I will revamp the whole puzzle-making process in this machine. It is 100% cursed. No doubt.

-End of Story line-

Apply classic Sudoku rules : Each row, column and bold-outlined region must contain the digits 1-9 once.

• Kropki rules are as follows : when two digits are consecutive, a white dot is placed. When a digit is half the other (e.g. 3/6, 4/8 etc.), a black dot is placed. All possible dots are given. A 1/2 pair can be indicated by either a black or white dot.

In this puzzle however, 5 of the regions decided to swap the colors of the dots : white dots behave as black ones, and vice-versa. It is part of the puzzle to find what regions are color-swapped.

The grey rhombuses indicate a kropki clue for which the color isn't specified.
