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

Really enjoyed this, but I think it was pretty tricky and never truly "gave up". Only the last few pairs were obvious.
But yeah, really rewarding break in and fun puzzle altogether.

some calculation required to sort out box 5.
after that, it's level 1.
23, there is only 1

Great break in. Near the end I had trouble only using logic. Great fun thx.
