A while ago SennyK kindly asked for more puzzles with yin-yang regions that are modifiers.
- Normal sudoku rules apply.
- Divide the grid into two orthogonally connected regions such that no 2x2 area is completely contained in a region. All cells in one region will have a value of D+1, where D is the digit on the cell, and all cells in the other region will have a value of D-1.
- Box borders divide lines into components with the same value product.
