I finally felt ready to set my first pure Killer Sudoku—so here it is!

Rules:

Normal Sudoku: Place the digits 1 to 9 in every row, column, and 3x3 box.

Killer Cages: Within each cage, digits cannot repeat, and they sum to the number in the top-left corner.

Solve online:

Solution code: Row 9

I was a bit skeptical on how a classic killer could be so good but you proved me wrong. This was absolutely gorgeous!

Thank you for this nice puzzle, Nordy! If your first pure killer Sudoku is that beautiful, you should definitely construct some more. Great setting!
