(Published on 8. February 2023, 21:15 by AnalyticalNinja )
Rules:
Normal sudoku rules apply.
Doublers: Within this puzzle there are nine doubler cells, which count as double their value for clues. (one doubler in each row, column, and 3x3 box that form a complete set of the digits 1-9)
Killer cages: Digits in cages sum to the small clue in the corner. Digits can't repeat in cages, and no cage can contain more than one doubler cell.
Playable with F-Puzzles or CTC (SudokuPad).

Exceptional puzzle! The use of doublers is very clever, as all the logic throughout the solve, and shouldn’t bother any solver, even the non doubler enjoyers. It has a taste of old classic ctc features such as Qodec’s Orbit and it should make a great new one!
