Rules: Normal sudoku rules apply.
Circles: Place nine circles in the grid: one in each row, column, and 3×3 box, with the digits in the circled cells forming a complete set of 1–9.
Cages and Xs: Digits may not repeat within a cage. If an X is in a row with circled digit A and a column with circled digit B, the digits in the cage containing this X sum to A×B (A and B need not be distinct).
Lösungscode: Row 2 with the circled digit in brackets, e.g. 123(4)56789.

Kaktuslav is the greatest setter of our time! As always, this puzzle was smooth, with brilliant deductions required, and a beautiful solve path.

Very nice! Solved it with only a few tiny hints from Simon...
The puzzle could have used a row and column for notes, though, to keep track of circle candidates.

How do you come up with this stuff :) Genius setting. This is one of those "stare stare stare GOT IT solve solve solve" puzzles. Loved it!

At the end after filling the boxes I feared a difficult sudoku, but then I found the logic.

I had to state at the rules for a couple minutes to wrap my head around them but totally worth it haha. Brilliant solve path really.

Wow, that was great fun. I had the right idea for the break-in quite quickly but then I made so many wrong deductions that I had to start over two times. :-)

Original and breathtaking logic until the very last deduction! Thank you.

I don't know how you manage to repeatedly come up with new and interesting rules.
3½ stars of difficulty for me.

Lovely puzzle. Requires some thinking to get started, but the positioning of the cages and Xs lead to a very smooth solve path. I rated it 3* rather than 2* because of the initial break-in.
