Normal Sudoku Rules Apply.
Kropki Dots:
Digits separated by a black dot are in a 2:1 ratio.
Not all dots are given.
Zipper Lines:
Pairs of digits an equal distance from the centre of a Zipper Line sum to the same total. For odd-length lines, the total is the digit placed in the line's central digit.
A valid fill for an even length, six cell, line would be [346:578] where 3+8, 4+7 and 6+5 all sum to 11. The total for each line may be different. Digits may repeat on a Zipper Line.
For convenience, centres of:
- Odd-length lines are highlighted with a bump/dot.
- Even-length lines are highlighted with a diamond.
Solution code: All digits from Row 9.

Fun stuff. The dot/diamond for visual clarity is also a really good idea.
