Fill each row, column, and box with the digits 1-9 without repeats.
Every 2x2 square region in the grid must have at least one prime digit (2, 3, 5, 7) and at least one non-prime digit (1, 4, 6, 8, 9).
Digits separated by a white dot are consecutive.
Digits separated by a black dot are in a 1:2 ratio.
Digits separated by a red dot are coprime. That is, their greatest common factor is 1. 1 is coprime with all integers.
The four digits surrounding a quadruple (circle with digits inside) contain the indicated digits.
The digits separated by the X sum to 10.
Solution code: Row 1, from left to right

Changed my estimated difficulty rating from 3 stars to 2 because after thinking it over, I figured that most of my difficulty in solving was simply due to lack of skill on my part.

I wasn't sure whether to make this 2 or 3 stars due to the amount of assistance I required.
