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 21.
Lösungscode: first 3 digits of row 9

Thank you for comment. I don't know how many stars to set. Solving contain hard steps. So i think it's not 2 stars. I selected 3 stars but i got too small amount of solvers (1 haha) so i decided to change difficulty to 4 stars.
