Crazy Parcels 2.3

This game consists of 4 stacks, which are different in kind and count of pieces. From time to time a new piece is inserted at the bottom of one of the stacks. Take the upmost piece of a stack and put it on top of another stack. Try to bring three identical pieces together. These three will fly away and one piece of a parcel will appear on the right side. If you have managed to finish the parcel on the right, the level is solved.
