Double Killer Sudoku
(Published on 15. December 2023, 21:57 by clover)
Killer: digits do not repeat within cages. Numbers in cages sum to the indicated total; a question mark in a total can stand for any digit and question marks are not necessarily all equal. A clue reading "even" indicates that the sum of the numbers in that cage is even.
Penpa
Solution code: Row 1, left to right

Awesome - solving while distracted, as usual, missed an option: got undistracted and found some clever stuff. Thanks for setting - great implementation of ruleset.
