The Super Square One is a 4-layer version of the Square One. Just like the Square One, it can adopt non-cubic shapes as it is twisted. As of 2009, it is sold by Uwe Mèffert in his puzzle shop, Meffert's.
It consists of 4 layers of 8 pieces, each surrounding a circular column which can be rotated along a perpendicular axis. This allows the pieces from the top and bottom layers and the middle two layers to be interchanged. Each layer consists of 8 movable pieces: 4 wider wedges and 4 narrower wedges. In the top and bottom layers, the wider pieces are the "corner" pieces, and the narrower pieces are the "edge pieces". In the middle two layers, the wider pieces are the "edge" pieces, and the narrower pieces are the "face centers". The wider pieces are exactly twice the angular width of the narrower pieces, so that two narrower pieces can fit in the place of one wider piece. Thus, they can be freely intermixed. This leads to the puzzle adopting a large variety of non-cubic shapes.

Famous quotes containing the word square:
“If magistrates had true justice, and if physicians had the true art of healing, they would have no occasion for square caps; the majesty of these sciences would of itself be venerable enough. But having only imaginary knowledge, they must employ those silly tools that strike the imagination with which they have to deal; and thereby, in fact, they inspire respect.”
—Blaise Pascal (1623–1662)
