Enjoy!
Rules:
-(sudoku) Place digits 1 to 9 each once in every row, column and 3x3 box.
-(lines) Each line is (at least) one of the following - region sum line, row sum line, or column sum line - i.e. it has the same sum in either all boxes, all rows or all columns it visits. Which rule applies to which line must be deduced.
example: for instance the line that goes through boxes 4, 7 and 8 satisfies (at least) one of the following:
- r6c1+r6c3 = r7c2+r7c3 = r8c3+r8c4 (row sum line)
- r6c1 = r7c2 = r6c3+r7c3+r8c3 = r8c4 (column sum line)
- r6c1+r6c3 = r7c2+r7c3+r8c3 = r8c4 (region sum line)

Lovely puzzle. Very clever and intricate logic and very interesting to untangle all the different options, especially the opening.
Very much enjoyed this one.

Not even that hard if you just keep asking the right questions. Splendid puzzle.

Here's a link to my solve of the puzzle. Took some struggling, but I finally got through it. It was a FUN struggling, though!

I think this one is too hard for me, 2 hours in and I only got two lines figured out... Would love a hint but not sure how that works on this website
.......
The way it works is that you write a hidden comment and the author of the puzzle can then edit it to provide answers to your questions.

Beautiful and intricate construction. It was somehow super hard for me to ask the good question a couple of times but no step was too hard
