Walking a Nine Line (Chaos Construction)
(Published on 5. February 2023, 16:19 by the_cogito)
Rules:
- Normal chaos construction rules apply.
- The lines in the grid are 9 lines. Each line must be broken into one or more strings of contiguous digits, each summing to 9. Every digit in a respective string belongs to the same region, and consecutive strings belong to different regions. These strings may not overlap.
- Indicated diagonals must be broken into one or more strings of contiguous digits, each summing to 9. These strings may not overlap.
Solve on f-puzzles
Solve on Sudokupad
Solve on Penpa+
Solution code: Row 9, then column 9 (18 digits, no spaces)

I keep a close watch on these chaotic lines,
I keep my eyes wide open, for that beautiful design,
I keep myself solving, the logic is so fine,
Because it's nine, I walk the line...
I find it very, very easy to go wrong,
I find my self alone, that path is very long,
But I keep solving, 'cause that where I belong,
Because it's nine, I walk the line !
Great puzzle! Thanks :)

Very fun puzzle. I only thing that makes it a bit strange is the fact that you can solve the puzzle while I only had 3 fully colored regions. The rest wasn't necessary

This might turn into a self-evident question but I'm just double checking: the region rule doesn't apply to the diagonals right? Meaning each 9-string on the diagonal may or may not be in the same region? Also by contiguous do you mean consecutive or just that they're next to each other in the puzzle?
By contiguous I mean connected or next to each other, it's unrelated to the value of digits. The rule for regions does not apply to diagonals, no.

Lovely, great region division logic, thanks!

Beautiful puzzle! The way the 9-lines, the regions, and the sudoku play off each other is really interesting and rewarding to find!

I had been staring at those corners in CTC link and couldn't figure it out. Then I clicked on penpa link and it has different line shape in top right corner. Is it possible to correct it for CTC link please
Author: Yes, fixed! Sorry about that lol
Bansalsaab: thanks. Beautiful puzzle.
