Doubler Counter Killer
(Published on 12. April 2023, 09:35 by Mad-Tyas)
Sudoku: Fill every row, column and marked 3x3 box with the digits 1-9.
Killer: In cages digits must not repeat and have to add up to the total given in the top left corner of the cage. Doubler cells (see next rule) contribute twice the digit in that cell to cage totals.
Doubler Counter: The grid contains an unknown number of doubler cells which need to be identified by the solver. Doubler cells may not touch each other, not even diagonally. A digit in a cell marked with a diamond equals the number of doubler cells in that row and column including the diamond cell itself. All possible diamonds are given (negative constraint) .
Have fun solving!
Solution code: Row 9 followed by column 9 (18 digits)

Amazing puzzle and fun solve throughout. I immediately smelled star battle logic, and the interactions with sudoku rules was brilliant! 4/5 stars for difficulty.

I wasn't confident at all while solving this one but I guess deductions I made were correct. This was definitely 5* for me.
