Puzzlerium tour: Quadrant Penta




Theme: Five in each quadrant 

Rules:  Place some of the pentomino shapes in the given grid without repetition. Pentominoes may be rotated and reflected but may not touch each other, not even diagonally. Every third cell used by pentominos, moving along the outlined quadrants and row by row within each quadrant, is given as a grey shaded cell. Given black cells, if any, will have to be left unused.
