Normal sudoku rules apply. These are NOT between lines.
For each pair of circles that are connected by a line, the sum of the two circles is the same as the sum of the digits on the line. Digits may repeat without restriction (aside from the rules of sudoku).
As an example, if two circles containing 7 and 9 are connected by a line of length 3, that line might contain the digits 6, 3, and 7.

Very nice puzzle that I solved in different stages. The stages were separated by longer periods of thinking about the implications of all those short lines until finally the penny has dropped. But even after that it wasn't an easy puzzle that collapsed only at the very end. Well done!
[Thank you Richard! Would you mind if I did some of your puzzles on my streams? -z]

Sure, go ahead! That sounds like an honour. :-) Can you provide the links to the streams in a hidden comment at the ones you solved?
[My loving husband records links to all of my solves here: https://zetamath.link/catalogue if you want to have a look! -z]

Wow! That is quite an impressive list! Must take a vast amount of time to record so many solves...

Very nice break in idea ! I thought it would be harder when I first looked at the puzzle, but once you get past the first digits, it all slides very quick. Thanks !

Really nice puzzle, I did struggle with this one for a while but eventually got to the end after focusing so long on few boxes. Thank you for this lovely puzzle! :)

Beautiful puzzle, would love to see more with this rule set! Not easy though, it got me stuck a few times. I actually got the break in by turning away the puzzle and pondering about it, which gave a priceless “aha!” moment :-)
