Skewb

The name Skewb was coined by Douglas Hofstadter in his Metamagical Themas column.

[2] In December 2013, the Skewb was recognized as an official World Cube Association competition event.

The centers only have two possible orientations, seen by scrambling a Skewb-like puzzle where the center orientation is visible (such as the Skewb Diamond or Skewb Ultimate), or by disassembling the puzzle.

The world record single solve is 0.75 seconds, set by Carter Kucala of the United States at Going Fast in Grandview 2024.

[4] The world record average of 5 (excluding fastest and slowest) is 1.52 seconds, set by Carter Kucala of the United States at CubingUSA Heartland Championship 2024, with times of 1.65, 1.45, (2.57), (1.37), and 1.45 seconds.

Some Skewbs feature concave sides for improved grip when turning.
