Through the Caverns [YYJ Pack]
(Published on 14. 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.
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.
Digits in circles give the number of cells (including itself) of the same shading as itself seen in all horizontal/vertical directions combined. Cells of the opposite shading block the vision.
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 cells that match the shading of r1c1 in row 4 (left to right) followed by digits in cells of that same shading in row 6 (left to right)

I loved this! I'm always a bit intimidated by yin yang puzzles for some reason, but this one was a joy to solve.

I overlooked the preface, so I didn’t notice I solved the puzzle already last june … Anyway, it was again a pleasure to solve.
