Skewb

A Skewb is a cube-shaped twisty puzzle with eight corner pieces and six center pieces. It twists around its corners, making it unique compared to traditional puzzles. The goal is to rotate the pieces to align the colours on each face.

The Skewb was invented by Tony Durham and was first marketed by Uwe Mèffert in the early 1980s. It was commercially released in 1982.
