Puzzle
The Skewb (/ˈskjuːb/) is a combination puzzle and a mechanical puzzle in the style of the Rubik's Cube. It was invented by Tony Durham and marketed by Uwe Mèffert.[1] Although it is cubical, it differs from the typical cubes' construction; its axes of rotation pass through the corners of the cube, rather than the centers of the faces. There are four axes, one for each space diagonal of 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 emphasize that it was part of a series including his first tetrahedral puzzle, the Pyraminx. The catchier name Skewb was coined by Douglas Hofstadter in his Metamagical Themas column. Mèffert liked the new name enough to apply it to the Pyraminx Cube, and he also named some of his other puzzles after it, such as the Skewb Diamond.[2]
Higher-order Skewbs, named Master Skewb and Elite Skewb, have also been made.[3][4]
In December 2013, Skewb was recognized as an official World Cube Association competition event.[5]
