Normal sudoku rules apply. Place the digits 1-9, once each, into every row column, and box. Adjacent digits along a violet multiple line must have one digit being a multiple of the other. (Every number is a multiple of 1 and itself.) Digits along a red thermometer must strictly increase from the bulb end.
I'm rating it 2 stars based on feedback, it is probably somewhere from 2-3 star difficulty.

I misunderstood “strictly increasing” and messed myself up for a while, but I was able to redirect and fix my incorrect pencil marks.

Not ** in my opinion. You have to work out at least two (or three) properties of this puzzle before you can look at the break-in. Since at least I have never seen something like this before Id go for "the break-in determines the difficulty", but that aside it was great fun to think and learn about how to approach this. Very well set!

I was a little confused whether or not the red thermometer also is a "multiple line", but it's not.
I think it might be less confusing if the explanation would refer to the multiple lines as being the purple lines.
Other than that I enjoyed it.

Fantastic puzzle. The constraints are fresh and the logic is interesting.
