Normal sudoku rules apply. Place the digits 1-6 once each in every row, column, and 2x3 box.
Renban: digits along a pink line are a set of consecutive non-repeating digits in any order.
Kropki: digits separated by a black dot are in a 1:2 ratio (i.e. one digit is double the other). Not all dots are necessarily given.
Solve in VariantDoku (iOS) or on SudokuPad.
Solution code: Enter the digits of row 6.

I was also very surprised with 1 star difficulty. I thought it would be at least 2.

Not sure if I was just missing something, but I got very stuck about 3/4 of the way through the puzzle, and only made progress after some coloring for disambiguation. The coloring revealed a huge a-ha moment, though, which was satisfying.
