Skewb Ultimate Rubik Magic Pyraminx Puzzle Ball Brain Teaser Cube Review
The Skewb Ultimate, originally marketed as Pyraminx Ball is a twelve-sided puzzle derivation of the Skewb, produced by famous toy-maker Uwe Meffert. Most versions of this puzzle are sold with six different colors of stickers attached, with opposite sides of the puzzle having the same color; however, some early versions of the puzzle have a full set of 12 colors.The Skewb Ultimate is made in the shape of a dodecahedron, like the Megaminx, but cut differently. Each face is cut into 4 parts, two equal and two unequal. Each cut is a deep cut: it bisects the puzzle. This results in 8 smaller corner pieces and 6 larger "edge" pieces.The purpose of the puzzle is to scramble the colors, and then restore them to the original configuration.he Skewb Ultimate has 6 large "edge" pieces and 8 smaller corner pieces. Only even permutations of the larger pieces are possible, giving 6!/2 possible arrangements. Each of them has two possible orientations, although the orientation of the last piece is determined by the orientations of the other pieces, hence giving us a total of 25 possible orientations.The positions of four of the smaller corner pieces depend on the positions of the other 4 corner pieces, and only even permutations of these positions are possible. Hence the number of arrangements of corner pieces is 4!/2. Each corner piece has 3 possible orientations, although the orientation of the last corner is determined by the orientations of the other corners, so the number of possible corner orientations is 37. However, the orientations of 4 of the corners plus the position of one of the other corners determines the positions of the remaining 3, so the total number of possible combinations of corners is only .
