Whereabouts (Diagonal Killer Sudoku)

(Published on 18. December 2024, 20:28 by sujoyku)

This is a bit of a “back to my roots” kind of puzzle, a classic killer sudoku with diagonal constraint. I like to thank all testers on the Sudoku Stream Team and CTC discord. As always, your feedback in the comments is highly 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.

- Diagonals: On the main diagonals, digits do not repeat.

- Killer cages: Digits in a cage sum to the clue in the top left.

Here you can solve the puzzle online:

Solve on Sudokupad

Solution code: Row 2 from left to right (9 digits in total)

Nice one, thanks, with some neat logic. Took me a while to figure out how to start but then it flowed smoothly.

Thank you for commenting, StephenR! The break-in is arguably one of the toughest deductions required in this puzzle. I am glad that you had a smooth solve thereafter.
Kind regards, sujoyku

Beautiful puzzle Sujoyku! It seems like I always solve you puzzles without really knowing what happened. I just keep chipping away and they end up solving like magic! Well done! Thanks for setting!

Thank you for your comment, meggen033! I am glad you enjoyed the solve. Concerning the "solving without knowing how it happened": I have felt like this in your puzzles as well sometimes. :D
Kind regards, sujoyku

I found the break through difficult. Really enjoyed piecing together the interesting logic between cages and diagonals. Thanks!

You are much welcome, NCtide, thank you for your comment! I think the break-in might be somewhat unexpected. It definitely is one of the most challenging deductions in my own solve path. I am glad you enjoyed the interaction of the cages and diagonals.
