This puzzle has 5 non-identical pieces in a wooden frame. The wooden frame has 2 trays, one on each side.
The challenge here is to take the puzzle pieces out and then try to fit them all back in the tray.
The second challenge is to flip the wooden frame and use the other tray on the other side. Now, try to put all the pieces in that tray.
Can you do it?
Great packing problem puzzle.
