The following is a puzzle that utilizes the power of parity, I made this one quite a long time ago and now I decide to share it here, I hope you enjoy!



Rules:

- Normal Sudoku rules apply: every row, column and 3x3 box contains digits from 1 to 9 each once.

- Digits within a cage don't repeat and must sum to the small number written in the top left corner of that cage.

- Digits along a gray line must have the same parity, i.e. all odd digits or all even digits, and they form a set of non-repeating consecutive digits in terms of their respective parity in any order. In this case, parity of each line has to be deduced.

- A black dot implies the 1:2 ratio relationship between two cells, a white dot implies the consecutive relationship between two cells. Not all dots are given.
