Magic 12
(Published on 8. September 2026, 05:08 by Todd)
Place the digits 1–9 so that each digit appears once in every row, column and 3×3 box.
Black dots: digits separated by a black dot multiply to 12. Every such pair is marked — an unmarked adjacent pair never multiplies to 12.
Killer cages: digits in a cage are distinct and sum to 12. Not every cell is in a cage.

Thanks @marco72 — glad you loved it!
And @thegreatgazoo, that negative constraint is sneaky — happy it clicked in the end!
