I'm curious to know of other puzzles that feature a BIG region sum line, feel free to leave a comment! Hope you enjoy :)
Rules:
Normal sudoku rules apply.
Region sum lines: Box borders divide blue lines into segments with the same sum. If a box contains multiple segments of the same line, each segment is counted as a separate sum. The sum may be different for different lines.
Quadruples: Digits in white circles must be present at least once in the cells the clue touches.
Solution code: Column 9
