Normal sudoku rules apply. Each 2x2 box in a grid has contain low digit {1,2,3}, middle digit {4,5,6} and high digit {7,8,9}. Digits along each thermometer must strictly increase from the bulb end. The sum of all digits inside each thermometer must equal 27.
Solution code: first 3 digits of column 9

Very nice and minimalistic! Felt like a 3 star puzzle, but solve time was still in the 2 star range. Thanks

Slowly moving right with global entropy logic after the break-in was a chore, but great puzzle nonetheless

I do love entropy constraint so I don't see any problems with that. But I understand what you are talking about. Thank you for the feedback!

I did not many global 2x2 puzzles. The break in with the thermos was amazing. The rest show my lack of experience and took me forever. Great fun thx.
