Product Placement (with SamuPiano)

(Published on 28. May 2026, 21:03 by sujoyku)

I had the great pleasure of setting a puzzle with my friend SamuPiano again. It is a Killer Sudoku with a little extra condition: The total of each killer cage equals the product of two of its digits. We like to thank all who tested the puzzle 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.

- Killer Cages: Digits in a cage do not repeat and must sum to the total which is given by the product of the two circled digits in the respective cage.

Here you can solve the puzzle online:

Solve on Sudokupad

Solution code: Column 5 from top to bottom (9 digits in total)

The break in on this took me quite a while. Once I got it figured out I realized this is the best puzzle I’ve solved in a while. Almost gave up last night, but so glad I finished it.
