Beautiful puzzle, not too hard with a little algebra.

When I got to the line in column 3 I had myself so convinced that I had broken it that I restarted the puzzle 3 times before finally realizing that it could indeed be filled. Loved it.

Nice ruleset and a smooth flow. I enjoyed the solve very much. Thanks!

I agree entirely with BBoom. An excellent puzzle that constantly seemed impossible until it wasn't. An excellent puzzle by a master setter.

This one had a lot of 'this is impossible' 'oh wait, I see this and now it's too easy' 'oh hold on, now this bit is impossible again'. Very fun journey.

Oof! It took me forever to find a break-in on this one. After that, I made steady progress.
Very nice and original ruleset! But I hope that Marty doesn't add diagonal redhead-lines next time. ;-)

The two upper horizontal lines are my favorite ones. Thank you very much for creating and sharing another incredible puzzle.

A split pea lines puzzle without the circles. Very intuitive and fun exercise. Thank you for setting it!

Fun puzzle. Thanks, @ marty_sears :).

Once I'd read the rules properly (the two digits are at the end of a row/column, not the line!) this was a joy. So many lines that "surely can't be useful yet", were actually giving a lot if asked the right questions.

Took me a couple moments to figure out how to approach correctly - but enjoyed very much once it clicked!

Very fun and somewhat mathy, right down my alley! I gave it 3* (could even be considered around 2.5)

so many lines made me think "surely this has to be broken now, right?" before resolving in just the right way (and then continually repeat that sequence until the puzzle was finished, what an excellent construction)
