Standard kakuro rules apply:
Put a number from 1 to 9 into each empty cell
No number appears twice in any horizontal block or vertical block.
Where a vertical block has a number above it, or a horizontal block has a number to the left of it, that block must sum to that number.
Additionally, kropki rules apply with a negative constraint:
For any two adjacent cells with a black dot between them, one of the cells must contain a digit that is double the digit in the other cell.
For any two adjacent cells with a white dot between them, one of the cells must contain a digit that is one more than the digit in the other cell.
If two adjacent cells don't have a white dot or black dot between them, neither cell is double the other and neither cell is one more than the other.

Solution code: Give the main diagonal (from top left to bottom right) followed by the other diagonal (from bottom left to top right) (30 digits)

Great construction! All the way difficult, yet definitely rewarding for me.

Clever use of the Kropki rules in this. I don't usually enjoy Kakuro but this was a fun challenge. Thanks
