Take Out 2
(Published on 16. July 2023, 21:36 by Ennead)
Normal sudoku rules apply.
Digits cannot repeat in cages.
Sandwich clues outside the grid indicate the sum of the digits between 1 and 9 in that row/column and must be deduced by the solver.
Each sandwich clue is one of the digits in its row/column and this digit must be taken out of the row/column when the grid is complete.
After the digits have been removed:
- All constraints must be valid.
- Each cage must sum to one of the sandwich clues.
Solution code: Row 8 followed by row 9 (18 digits, no spaces).

Fantastic puzzle! I can't believe I didn't realize this puzzle existed until today. I'd say it's even better than the original!

Love this ruleset. Hope there's a part 3 :D
- You're most welcome! Part 3 is already in the making. And it has a subtle twist. Thanks for your solve.

I had to break it once or twice to get the jist of it. Very nice puzzle, with a surprisingly elegant break-in. Steady carefulness required ;).
- Thanks for your persistence! And thanks for your lovely comment. Elegance is not something I'm usually accused of (in life, generally) so I'm happy to have achieved it in a small corner of my efforts.

Intriguing puzzle, looking forward to giving it a try! For total clarity, all constraints must be valid ONLY after digits are being removed?
(Not both before and after, which looks impossible for a 4-cage)
(One of the) sandwich totals = sandwich clues?
- Hello! Thanks for having a look at the puzzle. The constraints are not valid before you take out the digits. They are made valid by taking them out. Each cage sums to one of the sandwich clues. Sorry for the confusion!
