Yin Yang Area Division (Given Superset) (1246)
Instruction:
Put a black circle or a white circle into each cell. All cells with black circles must be connected orthogonally, and all cells with white circles must be connected orthogonally. Every 2×2 group of cells must contain at least one black circle and at least one white circle.
In addition, it must be possible to divide the cells with white circles into polyominoes such that every cell with a white circle in the grid is part of exactly one polyomino. The contents of each polyomino must match the supplied group of symbols (but can be in any order within the polyomino).
The polyominoes used must be part (or all) of the given set (with rotations and reflections allowed).
