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.
