A twisty puzzle with a spheric, hollow Skewb mechanism and transparent square windows to look inside. The eight triangles, which appear in four coloured pairs, are the connectors for four inner strings. Each string connects the two triangles of the same colour.
By twisting the sphere surface, the strings get knotted with each other.
Target is to bring them back in the initial state.
