Seeing Double

(Published on 7. October 2024, 21:08 by ul-Rhymm)

Normal sudoku rules apply: each digit, 1-9, appears exactly once in each row, column, and 3x3 box.

Killer cages: in cages, digits cannot repeat and sum to the number in the top-left corner. Colors are cosmetic to differentiate overlapping cages.

Figured out 1 region easily. The others took me longer because I had to avail myself of the secret.

Tantalizing. Even with the insight of Abadx helpful comment, the puzzle is tougher than 2 stars.
