Schrödingers Sauerkraut Sandwich
(Published on 21. February 2026, 14:21 by gdc)
This puzzle uses 2 schrödinger cells per row/column/region to allow some ridiculously long nabner lines and a spin on sandwich sudoku. Thanks ChinStrap, lmdemasi and KMD for testing. Hope you enjoy!
Schrödinger Sandwich: A number outside the grid is the sum of the digits between the S-cells in that row/column.
Nabner: A value on a sauerkraut colored nabner line must differ by 2 or more from every other value on that line. S-cells use the sum of their digits as values.
Solution code: Digits in the bottom row (row 8) from left to right. Ignoring S-cells (6 digits).

Loved this. Very clear what questions to ask but the answers are still interesting the whole way through.
