The '''Skewb''' (originally named the '''Pyraminx Cube''') is a twistable [[puzzle]] in the shape of a cube that is cut diagonally 2 times along each of 4 axes. It is a cube-shaped puzzle. It consists of 6 [[center]] pieces and 8 [[corner]] pieces (four of which are attached to the central core). Unlike the [[Rubik's cube]], which turns around faces, the Skewb turns around axes that go through its corners. It is a [[deep-cut]] puzzle - ie. each cut goes through the absolute center of the puzzle, and exactly half of the puzzle changes with each turn.

This puzzle was originally called the Pyraminx Cube by [[Uwe Meffert]], but Douglas Hofstadter suggested the name "Skewb", and it has been called that ever since.

== Skewb states ==

=== Scrambled skewb state ===

==== Previous step ====
* Scrambling from solved skewb state

==== Next steps ====
* Solve the first layer to have the First layer skewb state.
* Solve the first face to have the First face skewb state.
* Create a Petrus Block to have the Petrus Block skewb state.
* Match one center with one corner to have the 1 center + 1 adjacent corner skewb state.
* Permute 1st layer corners next to have the 1 center + 4 permuted adjacent corners skewb state.
* Match 1 center and 2 adjacent corners to have the 1 Roux Block skewb state.
* Create a Petrus block (2 corners and 2 centers between them) to have the Petrus block skewb state.
* Solve the 3 top corners to have the 3 top corners skewb state. 
* Solve as a Pyraminx to have the Pyraminx solved skewb state.
* Use the god's algorithm (R r' R' r x2 R r' R' r) to have the Solved skewb state.

=== Solved skewb state ===

The solved skewb state is when all the corner pieces and center pieces are correctly oriented and permuted, which makes all sides have only one uniform color.
