This is the sequel to my previous puzzle. This time I include even-length zipper line as well as normal zipper line.

Rules:

1. Normal sudoku rules apply.

2. Digits an equal distance from the center of a lavender Zipper Line sum to the same total. For odd-length lines, the total is the digit placed in the line's (circled) center.

3. Cells separated by a white dot must contain consecutive digits. Cells separated by a black dot have a 1:2 ratio. Not all dots are given.

Do have a go!
