This is a twisty puzzle similar to the Rubik's cube, but shaped like a tetrahedron (triangular pyramid). Each face is split into nine smaller triangular sections, and the challenge is to rotate the pieces to restore the puzzle to a solved state, with each of the four faces showing only one colour. Even if you have mastered the normal Rubik's cube: this is a fun variation.
