Kitchen Nightmare (Sandwich Chaos Construction)
(Published on 14. November 2023, 05:01 by Tacosian)
- Divide the grid into regions, each consisting of nine orthogonally connected cells. Each row, column and region must contain the digits 1 to 9 once each.
- Clues outside the grid give the sum of the digits sandwiched between the 1 and 9 in their respective row/column.
- In rows/columns that have a sandwich clue, all digits between the 1 and 9 must belong to the same region, and the 1 and 9 must not belong to that region.
- Cells with a black line between them must belong to different regions.
The following 6x6 example uses the digit 6 as sandwich crust instead of 9.

Penpa+ link: Penpa+ (For answer check, use green edges to separate regions)
Solution code: Column 2. Where there is a region border, type X (uppercase). In the 6x6 example, the solution code for column 2 would be 1X52X63X4.

It's funny seeing Agent's comment because the Tacosian experience only get more and more wild from here. This is easily the tamest Tacosian puzzle I've solved so far.

Excellent puzzle. Not as crazy hard as I expected after Agents comment, but it certainly required some deep thought.

Insane puzzle, one of the hardest CCs I remember solving. It's quite incredible how everything comes together in the end.

The break-in is not the hardest, but it gets harder...

Very nice puzzle, with cool logic. Don't agree with unrealistic difficulty (other comment), it IS difficult, and a lot of stuff to deduce all the way to the end.
