Rules:
Normal Sudoku rules apply, i.e. put the digits 1-9 in each row, column and box without repetition.
Region Sum Line: Box borders divide the blue line into segments with the same sum.
Renban: Digits on the pink line form a set of non-repeating consecutive digits, not necessarily in order.
Polarity line: Digits on the green line alternate between low (1,2,3,4) and high (6,7,8,9) digits. 5 can never appear on a polarity line.
Parity lines: All lines in this puzzle, regardless of colour, are parity lines: digits on a parity line alternate between even and odd digits.
Kropki: Digits separated by a black dot are in a 2:1 ratio. Not all dots are necessarily given.
Solution code: Row 1 (left to right)
