Normal Sudoku rules apply. Each coloured region is a killer cage i.e. the number given in the top left is the sum of the digits in the killer cage. Digits do not repeat in a killer cage.
Additionally, each killer cage could act as a thermometer, that is there is a path within each cage that is strictly increasing. For example, a cage of three with 1-3-9 is valid, but 1-9-3 is not. In the case of 2x2 boxes, this picture illustrates the rules.
This is part of a group of "Thermal Killer" sudokus. There are 3 different puzzles, and a bonus puzzle which requires the solutions of the 3 puzzles. This was inspired by Eggr's Hidden Clone series
This is, in my opinion, easiest of the three thermal killer sudokus.
Update I had mislabeled the letters in the puzzle. Apologies to everyone who saw the old version, and got stuck at the bonus level. I have switched the A and I in the puzzle here.
Lösungscode: Row 2, followed by Column 8

I enjoyed this more than I thought I would. The Thermal restriction to the cages is a really nice twist.
