Three's A Crowd
This one's a bit of a brute but I do think the logic in it is very satisfying!
Rules:
Irregular Sudoku Rules Apply
- Digits in every row, column and bold bordered region contain the digits 1-9
Normal Arrow Rules Apply
- Digits along an arrow's shaft sum to the digit in the circle
Hope you have a good festive season!
Enjoy the puzzle!
Solution code: Row 2 followed by Column 8 with no spaces

Fantastic puzzle! Lovely break-in and many cool tricks that can be done from there! I really enjoyed working towards resolving the middle arrows in rows 3 and 7. Irregular regions and arrow logic always make for some fun geometry... I saw this briefly on Zeta's stream but I knew it would be up my alley so I had to break away and solve it for myself xD

This is an absolutely brutal puzzle. The break-in is extremely clever, and just as hard to spot, and it doesn't get any easier after that.
I'm certain I missed some of the logic, because I broke down and bifurcated twice to get to the solution -- after spending more then twelve hours looking for the logical path.
