Rules:
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: Each 2x2 box in the grid has to contain a low digit (1, 2, 3), a middle digit (4, 5, 6) and a high digit (7, 8, 9).
Have fun solving!
Solution code: Row 1 (9 digits)

The hardest 2 star so far for me. Rather 3 star. The ruleset works great. But far from easy. Great puzzle thx.

Enjoyed how this one played out.
I think "satisfying" is probably the best description for this puzzle though..
