Normal Sudoku Rules apply. Every row, column and marked region in the puzzle must contain the digits 1-9 exactly once.
Additional Rules:
Region Sum Lines: Digits on a blue line must have the same sum in every box they pass through. They may repeat if allowed by other rules. If a line enters a box multiple times, every separate part of the line must add to the sum.
Little Killer: Digits on marked diagonals must sum to the number provided outside the grid. Digits on those diagonals may repeat if allowed by other rules.
Thermo: Digits on thermos rise from the bulb end.
Solution code: row 8

I agree with 2*. It was very pleasant and nice!

Well, I solved it in 39 minutes with checking. But at least i didn't wait until it showed up on Easy and Nice. I gave it 2* because i give everything 2*. ;)

Maybe a 2** puzzle, though.

Great puzzle. To me, there is too much constraint knowledge for a typical 1*. I go with harder 1* because of the break in. Great setting thx.

Just a super pleasant solve. It was longer for me than the vast majority of 1*, but it wasn't insanely difficult and it wasn't too easy. This is a perfect 1* puzzle. Bravo.
