Normal sudoku rules. Also, digits along an arrow sum to the digit in the arrows circle. Grey lines are palindromes i.e reads the same in both directions (palindromes continue straight at intersections). Digits in cages sum to the small clue given in the top left of the cage.
I think this puzzle ended up a little harder than I wanted it but nevertheless contains some interesting logic. Let me know what you think.
Solution code: Row 2 (left to right) and then column 9 (top to bottom) digits. 18 digits no spaces.

Quite a challenge but a good trip nonetheless.
Must combine the colouring process with the other elements to complete.

Fun to color. Challenging but not tediously so :)
