Play in Sudokupad
Normal sudoku rules apply.
There are no orthogonally connected pairs of cells which sum to 10 or 5 (XV negative constraint).
Digits on a line may not repeat, and sum to 10.
Digits in a cage may not repeat, and sum to 10.
Note: For clarity, cages are used instead of lines where cells are shared.
Solution code: Column 9 top to bottom

This is a great puzzle. I forgot the anti-V in the beginning, which helps place the lows and I forgot the anti-X in the later portions which helps place the highs, so a long solve for me.

That was a really nice puzzle. Started out coloring and then could switch half way through. Thanks!

I found this very pleasant indeed! The interactions with the lines and cages were interesting and the logic was fun. Thankyou!
