Rules: This is a Hybrid Thermometer, Killer, and Sandwich Sudoku. The rules are as follows.

Black circles with grey lines are thermometers. Digits on the thermometer must increase in value with the circle denoting the lowest digit.

Small numbers inside of the cages denote the sum of the digits which fall in the cage.

The numbers outside of the grid are sandwich clues. These denote the sum value of the digits between 1 and 9

UPDATE: I originally uploaded an old image of this puzzle that was missing a line which prevented it from having a unique solution. I have fixed this problem. I also, included a rule set at the top. Thank you to everyone in the comments who have been so helpful.

I am still a new setter and I am very eager to get some feedback. Your ideas are most welcome!

Solution code: Give the digits of Box 3 from left to right, top to bottom.

FINALLY! I must have just been overlooking silly mistakes.

Well, I have tried it three times now and every time I come up against an error. I see others have achieved it, so I'm wondering what I'm doing wrong. Ugh! Fourth try...

Originally I gave a hint in the description. Since then the difficulty rating on the puzzle has gone down and I have come to believe that the relationship I was worried about is more commonly known that I had thought. Thanks to everyone who has solved the puzzle to date! As this is only the second Sudoku that I've ever created I am thrilled to see people enjoying it!!

Oh my goodness, I uploaded the wrong image. The bottom right thermometer is supposed to go to the left one additional space!!

Nice puzzle. But as others stated there must be one more sandwich clue for uniqueness. Otherwise 2 digits may be switched..

@Orpheus I confirm the two solutions. Maybe you forgot a sandwich clue?

I assumed the clues outside the grid meant to be sandwich clues, the cages meant to be "killer" cages and the thermometers are starting with the lowest digit in the bulb. But you should definitely give some rules.

I reached a final position where there where two solutions possible. Otherwise very nice puzzle.

Since you asked for good ideas: The first one would be to give some rules.
