Cagey Sight-Line Yin Yang

(Published on 23. August 2025, 01:36 by yttrio)

This is the last of three Easter egg bonus puzzles that were originally published in the Yin Yang Journey puzzle pack. The bonus puzzles were ones that could have been part of the main pack thematically, but were created after the main pack was mostly finalized.

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 cannot repeat within a cage. The sum of the cells in a cage is equal to the total number of cells the marked diamond cell in that cage sees in all horizontal/vertical directions combined (including itself) that have the same shading as the marked cell. 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 6x6 in SudokuPad.




Solution code: Digits in cells that match the shading of r1c1 in row 6 (left to right) followed by digits in cells of that same shading in column 6 (top to bottom)
