Pentomino Division (Internal Star) (1128)
Instruction:
Divide the grid into pentominoes such that every cell in the grid is part of exactly one pentomino. You may not have more than one pentomino of the same shape (rotations and reflections of a pentomino count as the same shape). Each pentomino must contain exactly one star. The star must be in an internal cell of the pentomino (an internal cell is a cell orthogonally adjacent to at least two other cells of the pentomino). Some pentomino borders are already given for you in the grid.
