The Super 3x3x7 is made with a blue plastic core. The object of this puzzle is to scramble all 6 sides and then put them back so that each face has a solid color. This puzzle is extra challenging because it has 3 layers in both length and width, but is 7 layers high. This puzzle also has an added circle on both of the 3x3 faces making this puzzle even harder to solve.  The Super 3x3x7 is developed by WitEden who is a manufacturer and a wholesaler.
