This Fishers Cube is made from a high quality black plastic core. The object of this puzzle is to scramble all of the sides and then return it back to its starting position. Although this puzzle functions much like a 3x3x3, it is extra challenging because as it is scrambled it changes shape, so not only do you have to put all of the colors on the right face, but you also have to return it back to its original cube-like shape. The Fishers Cube was designed by Tony Fisher, from the United Kingdom, who has been making puzzles since 1981, and is now manufactured by Mefferts Rotational Puzzles. Uwe Meffert, born in Wernigerode, Germany, not only manufactures the puzzles, but has designed many of his own puzzles as well.
