Anti-Arrow

Puzzle Type: Anti-Arrow
Puzzle Link: F-Puzzles
CTC Software Link
Rules:
- Classic: Normal Sudoku rules apply.
- Arrow: Digits along an arrow branch sum to the number in the arrow's circle.
- Arrows may not overlap or share cells. They may cross, as long as they do not share any cells. The circle is considered to be part of the arrow.
- Any arrow that is completely or partially outside of the shaded regions must extend in a straight line from the circle, and may not bend. There is no such restriction on arrows contained entirely inside the shaded regions.
- An arrow’s circle may have more than one arrow branch attached to it. Each branch separately sums to the number in the circle. If a circled sum is possible under these rules, then there must be a branch from the circle.
- All possible arrows are given.
Lösungscode: Row 6, left to right

Absolutely wonderful! Loved it from beginning to end.

'Arrows may not overlap or share cells... All possible arrows are given.'
A strict reading of these rules combined would imply that an arrow such as 6-312 or 8-413 is not allowed, and yet I'm quite sure this puzzle is not solvable assuming such a restriction. Can you please clarify what is / isn't allowed?
@polar: Any arrow that is completely or partially outside of the shaded regions must extend in a straight line from the bulb, and may not bend. There is no such restriction on arrows entirely inside the shaded regions.
Second to last rule

Really cool twist on magic squares! Loved the mid-solve relabeling, and the ending is clever as heck :)

Absolutely wild that this solves cleanly! I hadn't realized it was possible to fill a box without creating a valid arrow.

Very interesting puzzle and brutally hard, at least for me :D I might have missed a clever trick or two.

Das war ein ziemlich schwerer Brocken. Aber schön war's schon ;-)
