Fillomino: Divide the grid into polyominoes and fill each cell with a number equal to the size of its polyomino. Polyominoes of the same size may not share an edge.

Yin-Yang: Shade some cells such that all shaded cells are orthogonally connected and all unshaded cells are orthogonally connected. No 2x2 area may be fully shaded or unshaded.

Parity: All odd polyominoes are shaded, while all even polyominoes are unshaded

“Yin” Arrows: Numbers on cells with an arrow indicate the number of polyominoes of the OPPOSITE shading seen in the direction of the arrow.
