Whispers In The Shadows

(Eingestellt am 15. Januar 2026, 08:23 Uhr von Scruffamudda)

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 square is completely shaded or unshaded. Every dot must touch a shaded cell.

German Whispers: Adjacent digits within the shaded region must differ by at least 5.

Kropki Pairs: Digits joined by a black dot are in a 2:1 ratio. Digits joined by a white dot are consecutive.

Brilliant puzzle! The basics are important and not that hard to discover, but the puzzle itself is a real challenge. Thanks

Took me quite to figure out the implication of the rules. I was staring at the grid and randomly coloring, hoping something would pop out. Once I got the initial start it was very smooth!

This was a lovely puzzle with some unexpected logic and some really interesting interaction between the constraints, the sudoku and the shading.

This one was pretty rough for me, but that might be due to my lack of experience with yin-yang

brilliant.
unfortunately, i ran out of paint, and was unable to complete the colouring, and so was unable to resolve the final deadly pattern - lol
