The Skewb is a magic polyhedron—that is, a
mechanical puzzlein the style of Rubik's Cube—invented by Tony Durhamand marketed by Uwe Mèffert. Although it is cubical in shape, it differs from Rubik's construction in that its axes of rotation pass through the corners of the cube rather than the centres of the faces. There are four such axes, one for each space diagonalof the cube. As a result, it is a "deep-cut" puzzle in which each twist affects all six faces.
Mèffert's original name for this puzzle was the "Pyraminx Cube", to emphasise that it was part of a series including his first tetrahedral puzzle
Pyraminx. The catchier name Skewb was coined by Douglas Hofstadterin his " Metamagical Themas" column, and Mèffert liked it enough not only to market the Pyraminx Cube under this name but also to name some of his other puzzles after it, such as the Skewb Diamond.
