Irregular Dots Sudoku 2018 - 1

Today we have an Irregular Dots Sudoku for WSC practice.

Digits do not repeat in any row, column or Bold outlined boxes.. Rows and columns are marked with numbers 1 to 9. There is a white dot between two cells if the difference of the digits they contain is equal to the number of a row/column they are part of. There is a black dot between two cells if the sum of the digits they contain is equal to the number of the row/column they are a part of. All possible dots are marked.


EDIT : Missing dot between R6C2 and R7C2 has been added.

Today we have another puzzle by our guest author Kumaresan. He has created a Counting Neighbours Sudoku.

Rules of classic sudoku apply. Number  in a  cell with  a circle tells you how many distinct digits you can find in up to 8 neighbouring cells (sharing edge or corner). Number in a cell with a cross tells you how many distinct digits you can find in up to 4 diagonally neighbouring cells (sharing a corner). All possible circles and crosses are drawn.


EDIT : There was a missing X at R7C3. I was too caught up in creating team rounds to check it properly. My bad.
