It's In the Negative (Sudoku)
(Published on 8. October 2021, 15:01 by PDN777)
Normal sudoku rules apply. Neighboring digits marked with V sum to 5. Neighboring digits marked with X sum to 10. ** All Xs and Vs are given - IE, the negative constraints are in force. Adjacent digits on a green whispers line must have a difference of five or greater. Digits in a cage must sum to the little number in the upper left, and may not repeat in the cage. As always, comments welcome!
Solution code: First row of puzzle, and fourth column of puzzle (read top to bottom). Enter as a string of 18 digits, no spaces.

Great puzzle! I thought the logical flow was very nice.
Edit: Thanks! I just ran thru it again - it has a solid level of struggle in it! ;-)
