It's my birthday!
And what better way to celebrate than with a thematic puzzle, just like last year.
That one is somewhat similar to this in some ways, but most of it is still quite different. You might like to check that one out too.
You might also like to try this one first if you've not seen Shifted x-sums before.
It would be a great birthday gift if you could also try some of my other puzzles, and help them get a rating:
Christmas theme sudoku
The Digits Are Paid Actors
Halloween themed encrypted Shifted x-sums
Whispering Worms
Rules:
Normal sudoku rules apply.
Along thermometers digits increase from the bulb end.
Horizontal outside clues are either X-sums clues or Shifted X-sums clues.
Vertical outside clues are either X-sums clues or Y-sums clues.
Figuring out which is which is part of the puzzle.
(There is no restiction on clues from both sides being the same or different.)
X-sums clues indicate the sum of the first X digits starting from the first cell from that side, where X is the digit in the first cell from that side.
Shifted X-sums clues indicate the sum of the first X digits starting from the Nth cell from that side, where X is the digit in the Nth cell and N is the digit in the first cell from that side.
Example: in a row with 514839762 the clue from the left would be 19 (3+9+7) and from the right would be 37 (6+7+9+3+8+4).
Y-sums clues indicate the sum of the first Y digits starting from the first cell from that side, where Y is the digit in the Xth cell and X is the digit in the first cell from that side.
Example: in a row with 514839762 the clue from the left would be 10 (5+1+4) and from the right would be 35 (2+6+7+9+3+8).
(In this puzzle Y-sums can only be in the columns.)
Lösungscode: column 3, row 8

Very smooth logic flow! Needed some combinatoric prework but with only some variants left it solved easier than expected. The combination with Y-sums I didn't know further but this really was useful. Glad that I saw your comments on Yann's puzzle (also a very special one)- I will give more of yours a shot (I like unusual settings). Well done!
--Thanks!

I was kind of hoping for more than one solve...

Very nice! When I found the logic in it, everything went smoothly.
(BTW,HAPPY BIRTHDAY(´▽`)ノ♪)
