Very different lines
(Published on 10. December 2025, 23:01 by PrpLTrtL)
This is my first puzzle so I hope it is worthwhile! I'm very open to criticism as I figure out what I am doing.
Normal sudoku rules apply.
Pairs of consecutive digits on a line all have the same difference throughout the line. (For example the line could be 147 or 123 as the digits all increase by 3 and 1 respectfully. 174 does not work as the pairs do not have the same difference.)
All lines have a different value for that difference between digits.
Solution code: Row 7:

Good job on your first puzzle ! I really enjoyed it, it was not too hard which is good to introduce a new logic :) So difficulty 1* in my opinion

Changed the color of the lines. Thank you for the feed back.

(For Waslip, or others similarly confused: each line has a different difference between values. So if one line is 2-4, you can't have another be 5-7, since those are both differences of 2.)
That was pretty neat. It's not too hard to quickly narrow down which line has which difference, but you've still gotta think a bit about it.
My main criticism would be that purple is close enough to black and to blue that it was a bit tricky at times to read the puzzle. Aside from that, this was great!

I'm confused on how 2 cell lines are supposed to work. My logic says they arent restricted at all so whats the point of them.
