It’s been a while since I last published an entropy Sudoku. This is mainly because, after 75 entropy puzzles in which I’ve explored the variant from various angles, I’ve come to feel that my work with this variant is more or less done. But perhaps, as with this puzzle, an idea will pop up every now and then that prompts me to add another puzzle to the collection.

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.

German Whisper: Adjacent digits on a green line must differ by at least 5.

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).

Odd: Cells with a grey circle have to contain an odd digit.

Have fun solving!
