Normal sudoku rules apply. Place the digits 1-9 without repeating in each row/column/box.
Each of the different lines uniquely follows one of the below rules. Each line must be assigned a unique rule, but may follow another line's rules in addition to its own. It is up to the solver to determine which line is which.
The Lines:
Renban - This line contains a run of consecutive digits, but they may be rearranged along the line.
Odd/Even - This line alternates parity. (13579/2468)
High/Low - This line alternates between high and low digits (1234/6789)
Palindrome - This line will read the same in either direction.
Region Sum - On this line, each segment of digits have an equal sum N. Segments are defined wherever the line crosses into a new box.
German Whispers - Digits along this line will have a difference of 5 or greater.
Happy solving! If you enjoyed this puzzle, check out the previous puzzle in this series!
Below is an example puzzle with the solution to solve as an introduction to how the undefined lines work. The following lines are in the below puzzle, but the lines are to determined by the solver.
Odd/Even - This line alternates parity (13/24)
Palindrome - This line reads the same in both directions
Sequence - This line reads exactly 1-2-3-4
Whispers - Digits along this line must have a difference of at least 2
Solution code: Column 8 followed by Row 6. 18 digits no spaces.

The aesthetic of the puzzle was slightly busy with a hint of color..
Quite tough to get a handle on how to track information, but fun to whittle down and isolate the different constraints.

Bonkers! Lovely, but bonkers... :P

I really liked it. The points of disambiguation between digits were very nice, and a relief to find. Thanks!

I loved this puzzle, but it did take me a few times to restart. Very clever, and once I found which line is which, goes very smoothly. The different size of lines are a bit distracting.
- Sniglett - Thank you for the feedback, glad you enjoyed!

I'm sorry that this is not getting any attention! I really enjoyed the previous two smaller puzzles in this series, and this is definitely on my list to solve (probably only sometime later this week though, unfortunately)
Incidentally, maybe you should add the smallest one to this page as a playable example, as a warm-up adn to give people a feel for it?
- Sniglett - I think adding the 4x4 is a great idea, thanks for the advice! I'll do that and also link the 6x6 when I upload that later today. I look forward to your solve!

Clarified that it is up to the solver to determine which line has each rule.

Instructions are a bit unclear. If it's up to the solver to figure out which line has which rule it might be a good idea to say that in the rules - if not it might be a good idea to mention which color the lines are.
- Sniglett - It is up to the solver to determine which line is which. I will make that more clear, thank you!

Please add to the rules the color of each line as well. Thank you
- Sniglett - It is up to the solver to determine which line is which, apologies for the confusion I will make that more clear!
