Sudoku Variants Series (438) - Regular Dots

(Published yesterday, 06:00 by Richard)

For this Sudoku Variants Project I have planned to publish a different Sudoku variant every week. I will see how long it takes before I am running out of ideas.

This puzzle uses the same ruleset as SVS #422, but now it is in a standard 3x3-grid. SVS #422 turned out to be solvable without the negative constraint, but for this one, the negative constraint is definitely necessary in your solve.

Regular Dots
Apply classic sudoku rules.
All adjacent cells that contain digits with a difference or a sum equal to the index number of the column or row are marked with a white dot (difference) or a black dot (sum).

Inspiration for this type comes from WSC2024.

The negative constraint played into the solve very nicely, thanks!

That missing white dot in the SudokuPad-version (c5r2,3) nearly left me lost in desperation! ;-)
Apart from this I really enjoyed another nice and approachable episode of the series. Thank you very much for creating and sharing another lovely puzzle.
