Low Killer X

Those are some pretty small numbers in those cages. Almost too small. Almost. I’ve been doing “Sudoku-X” puzzles almost as long as I’ve been doing Sudoku puzzles, but around these parts, we call those “diagonals.” If you’re feeling a bit of déjà vu, see also: High Killer X.

Rules:
Normal Sudoku rules apply.
Killer Cages: The digits in each cage sum to the small number in the top left corner of that cage.
Sudoku-X: Digits do not repeat along the indicated diagonal lines.
Colors are decorative only.

Estimated difficulty: 2 out of 5
