Rules:

Normal sudoku rules apply.

Place 9 nondivergent paths in the grid that travel orthogonally between the centers of cells.

Paths only turn when they encounter one of the given diagonal lines and may not pass through these lines.

A path cannot begin or end in a cell containing a diagonal line. Additionally, a path cannot cross the beginning or end cell of any path including its own.

Each path is associated with a unique value 1 through 9. The path must begin and end with this value. It also corresponds to the number of times the path turns.

The paths associated with the values 7, 8, and 9 are palindromes.

P.S. I couldn't get the diagonal lines to import into CTC properly, but it would be easy to draw them into a blank grid if you wanted to try this puzzle in CTC or another alternative software. If anyone knows how I could get this puzzle to work in the CTC web app, I'd appreciate advice.
