Skewb

Puzzle From Wikipedia, the free encyclopedia

The Skewb (/ˈskjuːb/) is a combination puzzle and a mechanical puzzle similar to 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.

The four turning planes of the Skewb bisect it as shown in this figure.

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 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]

In December 2013, the Skewb was recognized as an official World Cube Association competition event.[3]

Mechanism

The Master Skewb, a variant of the Skewb

The Skewb's pieces are divided into subgroups and have several constraints. The eight corners are split into two groups—the four corners attached to the central four-armed spider and the four "floating" corners that can be removed from the mechanism easily. These corners cannot be interchanged i.e. in a single group of four corners, their relative positions are unchanged. A floating corner can be distinguished by squishing down when applying pressure to the corner. 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.

Records

The world record for single solve is 0.73 seconds, set by Vojtěch Grohmann of the Czech Republic at Głuszyca Open 2026.[4]

The world record for average of 5 solves (excluding fastest and slowest) is 1.37 seconds, set by Ignacy Samselski of Poland at Cube Factory League Justynów 2025, with times of 1.22, 1.43, (1.16), 1.46, and (2.93) seconds.[4]
