This is my latest puzzle exploring the consecutive sum lines constraint. There are also easy and intermediate difficulty puzzles available in this series.

Rules:

Normal sudoku rules apply.

Arrows: Digits along arrows sum to the digit in the attached circle.

Consecutive Sum Lines: Within each 3x3 box, the sum of digits along a contiguous line segment is consecutive with the sum along the line segment in any box it directly connects to. If a line re-enters a box, each contiguous segment is a separate sum which may be different in value if permitted by other rules. For example, in box 5, the sum of [R4C4,R4C5] and the sum of [R5C4,R6C4] may be different but each sum differs from R5C3 by exactly 1.
i.e. Lines behave like region sum lines but the sum increases or decreases by 1 whenever the line crosses into a box.

Below is a simple 4x4 example to illustrate the rule set.
