A spatial logic or manipulative puzzle in the form of a 2x2x2 cube is provided comprising a body made of interconnected pieces, groups of which are relatively rotatable about three axes to exchange positions of the pieces, wherein exposed faces of the pieces are sculptured to define an image. Each piece has means for establishing a pivotal connection to other pieces of the puzzle, at least three planar faces for slideable abutment with adjoining faces of other pieces, and at least one exposed face which is sculptured to define part of an image. The internal mechanism is preferably controlled by a castellated spider fixed in relationship to one of the pieces. A mechanism of this type enables the pieces and components to be interengaged and secured together by pushing the last piece home and does not require internal screws or springs or gluing as in some other known cube mechanisms.
