Rules:
- Normal sudoku rules apply.
- Digits along the marked diagonal don't repeat.
- Digits separated by a white dot are consecutive. Not all possible white dots are shown.
- A digit on a line indicates exactly how many lines contain that digit. Eg: if there is a 5 on a line, then 5 lines contain a 5.
- The lines each have a different name, and must follow the corresponding rule. It must be determined which line is which.
LINE A - Dutch whisper: Adjacent digits on the line have a difference of at least 4.
LINE B - Parity: Digits alternate between even and odd along the line.
LINE C - Region sum: In each 3x3 box, digits on the line have the same total.
LINE D - Entropic: Each group of 3 adjacent cells along the line contain one low digit (1, 2 or 3), one medium digit (4, 5 or 6) and one high digit (7, 8 or 9).
LINE E - Renban: This line contains a set of four consecutive digits, but they can be arranged in any order.
LINE F - Nabner: No two consecutive digits appear anywhere on the line.
LINE G - Ten Line: Each cell on this line belongs to a group of adjacent cells which sum to 10. If there are more than one of these groups, they don't overlap.
The grey perimeter can be used for making notes.

Wow, this is a whole different game with the lines that you first need to reason about. I found it very hard to work my way through it, but very satisfying when I solved all the clues :D

Absolutely brilliant puzzle, satisfying and fun solve from start to finish. Took me a minute to wrap my head around figuring out the digits and combinations for each line, but once the ball gets rolling it really goes! Definite new favorite

I loved every minute of this puzzle, the break was extremely nice and once I mapped the correct combinations it was very smooth
Well done !

Cool puzzle! It would have been very nice with a penpa link for it, though. I made some notes down in box 9, but this was quite messy and less than ideal.

Very brilliant puzzle! I would consider this as 3/5 difficulty.

Excellent puzzle! Solves smoothly once you work out the combinations on the lines.

Very nice twist to the circles rule. Thanks for setting and sharing, @ marty_sears :).

Great puzzle! Found it very helpful to work out the numbers that had to be on each of the line types based on the restrictions before progressing.

That solve path was hard but awesome! The break-in was obvious but the puzzle kept on resisting until the end. Great rule and nice placement of the clues.

That is yet another brilliant puzzle using circle rule. I'm impressed with how many things you can do with this rule. Amazing!

What did I just solve, was that a sudoku puzzle or abstract art? It was either sublime setting or artistry, or both.

A thoroughly enjoyable puzzle, perplexing at times but always fair. Amazing work!
