Normal sudoku rules apply.
Knight's Move: Cells separated by a knight's move (in chess) must be different.
Killer: Digits in a cage sum to the small number in the top left corner of the cage.
Arrow: Digits along an arrow sum to the digit in that arrow’s circle.
Region Sum Lines: The sum of the digits along a blue line in a box is equal for each box that that line visits. In other words, r6c1+r6c2+r6c3 = r7c4+r7c5+r7c6 = r7c7+r7c8+r8c8+r9c8. Digits may repeat along the line if allowed by other rules.
Solution code: Column 1 then column 9, 18 digits.

I found it hard to progress in that puzzle until at some point where the blue line clarifies and everything collapses immediately with the knight constraint. Thanks for sharing!
