I was trying to create a completely different disjoint group puzzle, but I ended up making this one instead. Probably isn't too hard (but I literally have no way of gauging the relative difficulty of my puzzles since I am significantly less experienced at setting and solving than 95% of users here at least, but I digress), but I think the basic idea behind the puzzle is fun. I apologize for how confusing the center box looks. I really liked what I had in box 5, so this was the solution (at least it should be colorblind friendly!)
Rules:
Normal Sudoku Rules Apply (i.e. every digit from 1-9 must appear exactly once in every row, column, and box)
Disjoint Groups: Corresponding cells in each box must contain the digits 1-9 exactly once.
Arrows: Digits in cells along arrows add up to the digit in the corresponding circle.(The 4 colored lines that reside entirely inside box 5 are all arrows)
Renban Lines: Digits in cells along the pink line are consecutive (but not necessarily adjacent). ex:'156342' or '6758'

Ratio: The cells separated by the black dot have a 2:1 ratio (i.e. One digit is twice the value of the other).
Difference: The cells separated by the white dots are adjacent (i.e. one digit is one higher than the other)
