Skewb

The Skewb was invented by Tony Durham and marketed by Uwe Mèffert. It is a cubic shape modification of the Pyraminx. This puzzle turns 120 degrees, with each turn affecting all of the faces, hence its original name of "Pyraminx Cube". When Uwe Mèffert originally started to produce it, it was called the Pyraminx Cube, but Douglas Hofstadter coined the name Skewb in his column in the Scientific American (July 1982). Skewb became a WCA event in 2014, making it the latest addition to the WCA.
