Killer fillomino: Fill the entire grid with polyominoes according to the following rules:

1) A polyomino is a group of orthogonally connected cells.
2) Digits do not repeat in a polyomino.
3) Digits in a polyomino of size N sum to the multiple of N.
4) A digit in a circle displays the size of the polyomino to which that particular circle belongs. Each polyomino has its own circle.
5) No polyomino is contained entirely within a single 3×2 box; i.e. each polyomino crosses at least one box border.
6) Polyominoes of the same size cannot share an edge, though they may touch diagonally.
