Aim High! (YY)
(Published on 17. January 2026, 18:01 by SennyK)
I am close to finish my hard puzzle pack with growing grid and Yin-Yang in the fog :-)
Before that, I have prepared another hard Yin-Yang puzzle for you!
I hope you will enjoy and I would be really grateful for all the comments and ratings.
Normal sudoku rules apply.
Yin-Yang: Shade some cells in the grid so that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2×2 region is entirely shaded or entirely unshaded.
Values: A value of a shaded cell is equal to the highest digit within its all (up to 4) orthogonal neighbours; a value of an unshaded cell equals its digit.
Killer: Values in a cage sum to the total given.

Had to take a long break, then it seems like the entire puzzle unfolded in minutes upon return. Beautiful setting, and a wonderful break-in!

Amazing fun! 3* difficulty if you read the shaded values rule perfectly the first time. Love a good logic puzzle with no bifurcation
