Los démas (Killer sudoku)

(Published on 5. September 2024, 21:00 by sujoyku)

This killer puzzle should have a difficulty around 3 stars. But there is one deduction that I found so unusual that I almost was tempted to give it 4 stars. This step apparently is not strictly required to get to the solution, but I don’t know if there is another equally beautiful argument. For those interested I describe it in a hidden comment below. I like to thank all testers on the CTC discord. As always, your comments are much appreciated. I wish you joyful solving!

- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.

- Killer cages: Digits in a cage do not repeat and sum to the clue in the top left.

Here you can solve the puzzle online:

Solution code: Column 3 from top to bottom (9 digits in total)

A lot of complex interactions, but a joy as always.

Thank you for your kind words, OGRussHood! I am glad that you enjoyed the puzzle. Regarding difficulty: I believed it to be a 3 stars puzzle. So I agree with you on the "complex interactions" part.
Kind regards, sujoyku

Muy Lindo! This was a pleasure to solve, I just wish I spoke enough Spanish to leave a full colorful comment en Espanol.

Gracias, Calvinball! Mi espanol no es mejor. :) If you write me a spanish comment, I might need to look up a lot. But I love a spanish title for my puzzles from time to time. I am glad that you enjoyed the solve.
Kind regards, sujoyku

Nice puzzle! I didn't see the intended deduction, but I didn't need it; I never had to bifurcate.
