Normal sudoku rules apply. Orthogonally adjacent cells must not contain consecutive digits. Neighboring digits marked with a black Kropki dot have a 2 to 1 ratio. Not all dots are given. Digits on a purple renban line must be consecutive, but can be in any order. Digits may not repeat on a renban line. There is a four-cell tilted-T renban line in box 2, and another in box 8. I think this puzzle is 3 stars out of 5 for difficulty for many solvers. As always, comments welcome!
Solution code: First row of puzzle, and fourth column of puzzle (read top to bottom). Enter as a string of 18 digits, no spaces.

Nice flow right from the start, a little hump in the middle, but a smooth descent to the finsih.
Great puzzle, thank you PDN
