A circular mosaic puzzle for retaining a puzzle design that is adjustable between ordered and disordered configurations. Plural circular mosaic substructures, each with a display surface, a central section, and four peripheral sections, are rotatably retained relative to a frame. Adjacent circular mosaic substructures have overlapping circumferences. Each peripheral section has opposed convex arcuate surfaces, and each central section has four concave arcuate surfaces for receiving one or more peripheral sections. Concentric actuation knobs can be retained relative to reverse surfaces of the substructures. A receiving track in the frame rotatably receives the circular mosaic substructures. The receiving track corresponds in shape and size to the shape and size of the overlapping circular mosaic substructures. The track can be a depressed formation within the frame that is laterally bounded by the border structure. Correspondingly disposed apertures in the track permit passage of hubs to permit manipulation of the substructures.

A multiple rhombic dodecahedron puzzle includes a plurality of wooden puzzles arranged in a multiple rhombic dodecahedron. The multiple rhombic dodecahedron is equivalent to a cube formed by a plurality of rhombic dodecahedrons connecting to each other. Each of the wooden puzzles includes two unit elements. The two unit elements are connected to each other and are the same others. Each of the two unit elements has a plurality of surfaces. Each of the surfaces has a diamond shape or a triangular shape. Two of the surfaces which in the triangular shape are connected to each other in order to form a concave shape, and the surfaces are surrounded to form a closed space.

A symbolic unity ceremony puzzle product in a tray and a method of assembly thereof for a unity ceremony are provided. The symbolic unity ceremony puzzle product comprises a tray comprising a circular cavity, edge puzzle components, and central puzzle components. Each edge puzzle component has a shape of an annular sector comprising an inner arc, an outer arc, and two radially oriented sides. Each of the edge puzzle components is configured to one of engageably connect and contiguously connect with adjacent edge puzzle components. Furthermore, the edge puzzle components are positioned along a peripheral edge of the circular cavity of the tray to form an annular puzzle component. The central puzzle components are positioned in the tray within the annular puzzle component formed by the edge puzzle components. Each central puzzle component is configured to one of engageably connect and contiguously connect with one or more adjacent central puzzle components.

A national-flags jigsaw puzzle globe and its jigsaw puzzle structure are provided. The globe includes a supporting frame and a rotatable cube structure connected thereof. Each surface plate of the cube structure includes a plurality of installing holes for the puzzle pieces. Each puzzle piece has a national flag picture to represent the country. The country's information, such as the country's name, may be displayed on the surface plates near to the installing hole. The backside of the puzzle piece has a protruding structure with unique profile, and the sidewall of the installing holes has the corresponding profile. Therefore, the puzzle piece only can be fitted to the corresponding installing hole. Thus, the relationship of the country's information and the national flag picture is enhanced with an entertaining and informative manner.

A cube packing comprises two truncated pyramids configured for a packing mode and a stand mode. In the packing mode, each pyramid touches three faces. In the stand mode, a first pyramid lays on a substantially horizontal surface, a second pyramid rests on the first pyramid and a large cube resides in the second pyramid while having a vertex pointing upwards. The large cube consists of eight small cubes, which in turn consist of a first group of eight pieces and a second group of 16 pieces. Each small cube includes one piece of the first group and two pieces of the second group. The eight pieces of the first group include at least three pieces different from each other at least by color, and may include at least three pieces different from each other at least by shape. In addition, the 16 pieces of the second group include at least three pieces different from each other at least by shape, and may include at least three pieces different from each other at least by color. Each small cube consists 333 mini-cubes by volume.
