Sudoku: Fill every row, column and marked 3x3 box with the digits 1-9.
Killer: In cages marked with a black dashed line digits must not repeat and have to add up to the total given in the top left corner of the cage.
Entropy: The low digits (1, 2, 3), middle digits (4, 5, 6) and high digits (7, 8, 9) are defined as three different groups. In the finished grid each 2x2 box has to contain at least one digit of each group.
Have fun solving!
Solution code: Row 1 followed by column 1 (18 digits)

Extremely difficult, every time I finally felt like I broke through there was another wall to climb. I agree with shteev about the ending.

Really tough. The start was nightmarish but seemed fair when I eventually figured out what I was supposed to be thinking about. The end tho... I'm not sure I found the correct solution path, mine was pretty long and involved

Absolutely beautiful. This really should be a 100%-rated puzzle. 3-stars difficulty.

Great puzzle, close to TEN stars difficulty for me though! Very satisfying to find all the necessary steps.

Wie immer bei deinen Entropiesudokus ein sehr schöner Einstieg. Mittendrin eine (zumindest für mich) nur sehr schwer zu findende Schlußfolgerung, danach mehr oder weniger flüssig und schön. Danke!
