Irregular Differences
(Published on 9. June 2021, 01:00 by Lisztes)
Irregular Sudoku rules apply. Each row, column, and 9-cell region contains each number from 1 to 9 exactly once.
The white dots represent a difference of 1, the black dots represent a 2:1 ratio between two cells. Not all possible white and black dots are indicated, a.k.a. no negative constraint.
The puzzle is also available online.
Solution code: Row 6 and column 6.

Btw you don't need to create a new tag for irregular regions/sudokus. The written tag "Irregular" links to 55 other puzzles.
