Rules

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. (135/246)
High/Low - This line alternates between high and low digits (123/456)
Palindrome - This line will read the same in either direction.

What a beautiful puzzle. Even though it is small, it's brilliant.

Glad to see this one published here as well! It can absolutely stand on its own and is a worthwhile addition, not just as a warm-up to the 9x9, but it has surprising depth and cool logic for s small puzzle with what appears to be just a bunch of random squiggles!
- Sniglett - Thank you!
