Normal sudoku rules apply.
The grey lines are palindromes that read the same in both directions.
Digits in cages sum to 12; negative constraint applies -- no unmarked dominoes sum to 12.
Digits separated by a V sum to 5, digits separated by X sum to 10, (not all V’s and X’s are shown).
Have fun, leave a comment if you enjoy the puzzle!
Solution code: Column 2 followed by Column 3

Thank you so much for the wonderful birthday present. The fact that I had to wait 43 years for it made it all that more special. Definitely a fun solve.
