A three-dimensional jigsaw puzzle consisting of one or more two-dimensional puzzle parts, each consisting of two or more jigsaw puzzle pieces. The puzzle parts can interconnect using leg and hole connectors to form the three-dimensional object. Each puzzle part is fixed using fixing sheets which are precut to match the format of its corresponding puzzle part. Each puzzle part can have puzzle pieces which can be bent to create corners. The bending is achieved by applying a reinforced tape along the bending line on the inner side, and by having a straight cut on the outer side of the corner penetrating the cut through the puzzle piece, but without cutting the tape. The puzzle pieces are laminated with paper that can bear an image on both sides. The puzzle parts can have a reinforcement bar glued on the non-visible side so that they retain the desired planar shape.
