A Yin Yang component has been added to come up with this interesting sudoku variant. Hope you enjoy, rules below:

• Normal sudoku rules apply.
• Highlight all cells in the grid with one of two colors; one dark (grey) and one light (yellow). (A 2x2 area is allowed to be filled with the same color.)
• - Each color will result in a single orthogonally connected region.
• The digit in a square cell specifies how many dark (grey) cells exist in the neighboring cells (horizontally, vertically and diagonally) including the number cell itself.
• The digit in a circle cell specifies how many light (yellow) cells exist in the neighboring cells (horizontally, vertically and diagonally) including the number cell itself.
• All circles and squares have been given.
