Rules:

-----Normal 9x9 sudoku rules apply: In every row, column and in every 3x3 box the digits from 1 to 9 have to appear atleast once with no repeats.

-----XV-pairs: Cells joined by an X or V must sum to 10(X) or 5(V).

-----Difference kropki: Cells with a white kropki between them are consecutive.

-----Ratio kropki: Cells with a black kropki between them are in a ratio of 1 to 2.Wich means you have the following posibilities, 1-2, 2-4, 4-8 and 3-6.

-----Entropic line(SALMON): Every 3 consecutive cells along an entropic line must contain a low digit(1-2-3), middle digit(4-5-6) and high digit(7-8-9).

-----Parity lines(ORANGE): Digits along a parity line alternate between odd and even.

-----Modulo 3 line(RED): Every 3 consecutive cells along a 3-modular line must contain a complete set of residuals modulo 3. i.e: one from (1-4-7), one from (2-5-8) and one from (3-6-9).
