Hello everyone! This is one of those folded puzzles, where regions overlap. I hope the instructions are easily understood, please leave me a message if it is not clear.
There are nine 3x3 regions crammed into this 7x7 grid. The light red lines indicate cells which are in more than one region. These are the shared border cells. (Border cell digits may not repeat in either region, so R3C2 could not be either R6C1 or R1C3 etc.)
Place the digits 1-9 without repeating in any row, column, and 3x3 region.
Digits on an arrow sum to the number in the attached circle. Digits may repeat on an arrow.
Note: R4C1 has a three cell arrow which may be obscured by the red line.
Solution code: Column 6, top to bottom.

Wow - incredibly smooth solving. I colored it up to help "see" the borders and numbers, and it was a freaking sweet solve, thanks!
