Normal Sudoku Rules apply. Cells a chess knight's move apart cannot contain the same digit. All lines contain a non-repeating set of consecutive digits in any order (renban). White dots join consecutive digits. Black dots join digits in a 1:2 ratio. Not all dots are given.
Solution code: Row 1

I was surprised this was a three star difficulty - I would have thought two stars.
I did spend some time not really making much progress first, but once I figured out one really basic deduction I'd overlooked, it felt like a one star puzzle and I finished it in just over twenty minutes.
It was a wonderful and smooth solve regardless of difficulty, and I am completely in love with the pretty rainbow design!

Great Puzzle, really creative break-in I think much more of a 4-star than a 3-star. Thanks!

Loved that! And making the renban different colors was very helpful, thank you :)

Took me longer than I'd like to admit, but I never felt stuck. Lots of great little deductions along the way. Thanks for setting!

Colorful fun! One nice deduction to get going, then a fun experience in finding the loose ends to untie the knots.
