Sandwich Break [YYJ Pack]
(Published on 21. February 2026, 01:00 by yttrio)
This was originally created for the Yin Yang Journey puzzle pack. Links to previous puzzles in the pack are below:
Go Yin Yang
Through the Caverns
Rules:
Normal Sudoku rules apply.
Yin Yang: Shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 area is fully shaded or fully unshaded.
Numbers outside the grid are yin yang sandwich clues: they give the sum of the digits in unshaded cells in that row or column that are between the outermost shaded cells of the row/column. Note that there will always be at least two shaded cells in every row/column that contains a clue.
6x6 Example:
The image below shows a sample 6x6 puzzle and solution with the same rule set.
Play the example in SudokuPad.
Solution code: Digits in shaded cells in row 2 (left to right)

I remember this puzzle being one of the highlights in a full pack of highlights, it's a real highlighter.
