Description
The Luban Sphere takes the idea of the Luban lock into a spherical shape. It is an assembly puzzle in the Kong Ming Lock series from QiYi, the Chinese brand best known for its speedcubes, in which six pieces fit together to form a ball held together solely by the shape of its joints.

What is a Luban lock?
Luban locks, also known as Kong Ming locks, are the Chinese version of burr puzzles: puzzles made of notched pieces that hold one another together without glue or screws. Tradition credits their origin to the carpenter Lu Ban or to the strategist Zhuge Liang, known as Kongming. Unlike a Rubik’s cube, nothing turns here: the pieces slide and come apart.
How it works
The challenge is the usual one in the series: separate the pieces in the order the design allows and then retrace your steps to form the sphere again. The curvature makes it harder to read than a burr puzzle with straight pieces, because the notches are less visible, and the round shape makes it comfortable to hold in one hand while you study it.
