I Don't Want to Miss a Thing (Diagonal killer sudoku)

(Published on 16. February 2026, 18:06 by sujoyku)

I am always intrigued by how powerful a diagonal constraint can turn out to be. This is a classic diagonal killer sudoku whose difficulty might be around high 2 or low 3 stars. I like to thank all testers and wish you joyful solving!

Rules:

- 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 must sum to the clue in the top left.

Here you can solve the puzzle online:

Yeah, low 3* for me. The break is fairly nuanced. But a fun puzzle in any case!

Had a lot of fun testing this one! Not hard at all if you're used to thinking about cages that have similar totals and know how to think a bit about diagonals strategically, but elegant nonetheless.

Thank you for this wonderful gift, Sujoyku! Felt more like a 2* for me but that could also be due to the constant exercise over the past years because your puzzles are across the board high-class and I don't wanna miss a thing.
