Entropy Antimatter
(Published on 5. March 2024, 16:24 by Mad-Tyas)
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 the "values" 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).
Antimatter: If a digit is orthogonally adjacent to one or more digit of the same entropy group (i.e. {123}, {456} and {789}) its "value" becomes negative.
Have fun solving!
Solution code: Row 9 (9 digits)

Mad-Tyas entropy sudokus always feel good to solve.

Kept getting about halfway through the solve, appreciating some really great logic, but running into a contradiction I just couldn't track down...
Turns out that the rules do not, in fact, say that antimatter is created by 'diagonally adjacent' cells... Oops ^_^

Exceptionally high quality puzzle as usual! Well, that is not exceptional then I guess. Thank you

Kniffliger Beginn, dann wieder sehr elegant. Danke!

Another beauty. Thanks for exploring the entropy with new constraints.
