This is a twisty puzzle similar to the Rubik's cube, but instead of using colours to indicate which pieces go where, the layers of the cube are different thicknesses - so when it's twisted, the pieces stick out! The cube is solved when it's back into a cube shape, and all pieces are flush with nothing sticking out. Even if you have mastered the normal Rubik's cube: this is a fun variation. Manufactured by twisty puzzle experts QiYi.
