X-Centric [Killer Sudoku X collab with Twototenth]

(Published on 9. November 2022, 21:59 by Malrog)

Twototenth and I collaborated on this puzzle, which came out of an idea I had presented in a much smaller puzzle. Twototenth cleverly upscaled it to 9x9, and we polished it up together. Big thanks to him for suggesting the collab, it's been a lot of fun and I think we've made something rather good as a result.

Rules:

Normal sudoku rules apply.
Digits may not repeat along the main diagonals, which are marked.
Digits in cages must sum to the total in the top-left corner and may not repeat.

Wonderful puzzle! Solves very smoothly when you get going. Lovely interactions all over the place with the cages and the diagonals. Interesting how powerful the interactions are between box 5 and the cages it sees. Thank you!

So glad you enjoyed it, thank you for solving, and for your kind comment.

Thank you for this wonderful puzzle, Malrog and Twototenth! The solve felt to me that you really have to ask the right questions. I got a bit stuck in the middle, but then noticed that I had missed a "simple" diagonal deduction for quite some time. It was a very enjoyable challenge.

Thank you for your wonderful comment! So glad you enjoyed the solve - those diagonals definitely do some work in this puzzle!
