Forwards & Backwards

Normal sudoku rules apply.
The purple lines are renban lines. Digits on renban lines must form a run of consecutive digits in any order. For example, 7568 is an acceptable set of digits to have on a renban line.
The blue lines are nabner lines. Digits on nabner lines cannot repeat, and no pair of digits on a nabner line can be consecutive. For example, 1749 is an acceptable set of digits to have on a nabner line.
The cell with the circle is odd.

Nice puzzle, thanks. I think I may have missed a bit of logic at the start though.

Nabnered !
Love the way the nabneR and Renban work together here. The originality and variety of your puzzle rulesets amazes me.

Can consecutive digits appear on a nabner line, so long as they are not next to each other? (e.g. is 1526 a valid nabner line?)

Very nice logic!

Great puzzle! It took me a while to find an opening move, but the rest of the solve went without a hitch. I quite enjoyed it :)

Quite different logic than the first nabner puzzle.
