I had this idea of making a puzzle where you don't know exactly which number it is. For example is it 3 or 8, or 3 or 5, or 8 or 9. I am really happy with the result, hope you all enjoy it.

Rules:

Normal 6x6 sudoku rules apply.

The two digits joined by a black dot have a ratio 1:N indicated by the number N on that dot.

The two digits joined by a red dot have a sum N indicated by the number N on that dot.

The two digits joined by a grey dot have a difference N or have a ratio 1:N indicated by the number N on that dot.

The two digits joined by a pink dot have a difference N or have a sum N indicated by the number N on that dot.

Digits in a larger circle must appear in the surrounding four cells at least once. All four numbers are in the circle and are listed in numerical order from top left to bottom right (although digits may repeat.)

Placing correct digits might clear the fog or might not clear the fog from surrounding cells, possibly revealing more clues.
