Rules
Standard Fillomino rules apply. In addition, draw a loop (1-cell wide) that does not touch itself orthogonally, but may touch itself diagonally. The loop either goes through all or no cells of a Fillomino region. The loop does not go through cells with a circle. The number in the circle indicates the number of cells in the (up to) 8 surrounding cells that are used by the loop.
Fillomino rules
Divide the grid in regions, such that no two regions of the same size touch orthogonally. Each cell contains a number that indicates the size of the polyomino it is in.
