Entropy X-Sums
(Published on 30. January 2024, 10:12 by Mad-Tyas)
It's certainly not the most obvious combination, but I had an idea for an interesting break-in. And surprisingly, there was a very elegant and minimalist way to turn it into a complete puzzle.
Rules:
Sudoku: Fill every row, column and marked 3x3 box with the digits 1-9.
X-Sums: A clue outside the grid gives the sum of the digits in the first X cells looking from that direction, where X is the digit in the cell next to the clue.
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 9 (9 digits)

Nice puzzle. I, like some others in the comments, went a little bifurcatory at the beginning.

It is astonishing! And I can't believe it only takes me 36 minutes to solve! It is indeed a lot easier than other monstrously difficult entropy puzzle.

Tough but fun. Thanks, @ Mad-Tyas :).

Extraordinarily difficult, for me.

Great puzzle! You made my day with another puzzle with my favorite constraint. For a change I didn't find it very hard, so maybe I finally have learned something. I loved the break-in. Thank you
