Standard Sudoku rules apply.
The board has different colored lines on it. The two cells connected by the lines may be one of the following four cases:
- Sum is 5;
- Sum is 10;
- Difference is 1;
- Ratio is 1:2.
Lines of the same color represent the same situation; lines of different colors are different and need to be inferred by the solver. Not all lines are given.
Identical pairs are directly connected by only one color line (e.g. 2 and 3 are connected by a line with a difference of 1, they are not connected by a line with a sum of 5)

If you are not sensitive to the color distinction in the diagram, use this link , which distinguishes the four colors using different shaped lines.
Solution code: Row 5 and Row 9

Very fun. I was a little confused at the end until I realized that there are two orange lines in box 4. Pretty obvious I suppose, but at first I thought that counted as one line and I was left with a deadly pattern.

That was a fun one! Loved how nice it was to figure out the nature of each line. Thank you so much!

Thanks so much for this lovely puzzle! Not too difficult to work out which lines were which but still managed to surprise - a lot of fun.

I haven’t even attempted the puzzle yet, but had to create an account so I could post and say thank you, thank you, Thank You(!) for the colourblind friendly option. Without it I’d have to skip this.

Absolutely amazing puzzle. Quite easy for an experienced solvers I guess, but for me it was a bit challenging at least at the beginning.

Fix the wrong line color.
-THX @Franjo @sacklunch @chain.reader
Add a version for people who are not sensitive to color distinction.

fun, did not need to use your extra dupe pair rule,
and it's good that I didn't... since the final grid has a dupe pair on different colours as Franjo mentioned
---------
Thanks for report! There was a mistake when I changed the color for all lines, and the problem has now been corrected!
In fact, the rule appeared for another version that all lines are gived. In this version the rule can be unused, so I have an error ......

Great puzzle, I enjoyed that! I agree with @Franjo - there's one pair of digits in the finished grid which are connected with two colors of lines. I think that last instruction can be ignored/removed.

I am colorblind, and the colors that are not blue and red (green and orange?) are very difficult to distinguish. I brought the image into a photo editor and changed the color balance to distinguish them.
---------
The four colors are red, green, orange and blue.
Now I have created another version to make it distinguishable without the need for color. Hope you enjoy it :)

Nice, but - there IS one special pair of numbers connected once by a red line and once by a yellow one! Or maybe I misunderstood the rules?
