More difficult than it may appear, the objective of the 4 Steine Mini is to remove the four cubes from the frame and reassemble. What you don't see in the solved state is that each cube is not square! Cut with slightly angled sides, it is difficult to know which cubes should fit together in order to lay flush with the top of the frame. A classic scratch-your-head packing puzzle from Jean Claude Constantin.
