The present invention relates to three-dimensional puzzles with segments capable of changing position in relation to one another, said segments having guides for allowing the movement of movable elements. According to the invention, the movable elements are configured in the form of permanent magnets, wherein the movement of each magnet is limited by its own guide, and each magnet is capable of being positioned in at least one of two end positions, wherein the guides in the movable segments are arranged to allow different magnets to interact with one another and to change position relative to movable elements. Movement of the magnets is provided by both the attraction and the repulsion of different magnets. The technical problem addressed is that of increasing the existing assortment of puzzles having movable segments.

A sliding intelligence toy including a housing, two fixed pads fixed at two inner ends of the housing, a movable pad located between the two fixed pads, a connecting shaft structure passing through the two fixed pads and the movable pad, a first block structure and a second block structure. One end of the connecting shaft structure sticks out from one end of the housing and can move along the axial direction of the housing and rotate along the radial direction of the housing under the action of an external force, and the movable pad can rotate with the rotation of the connecting shaft structure. The sliding intelligent toy has a simple game principle, can be operated easily and flexibly and set clear levels of difficulty, which is challenging.

A panel and a system for use in building a lightweight structure are provided. The panel, made of a film or a sheet capable of being curved or bent with fingers, includes a body in a geometric shape circumscribed by straight or curved edges, and at least one joint formation along the edge for panel connection. The joint formation has tabs separated by at least one gap. Each tab expands bilaterally and proximally from the body at its base, and each gap is positioned along the edge so as to accept the base of the tab. The joint formations along the edges of varied curvatures are alignedly, hingedly, and detachably interlocked with each other by twisting the panels with fingers to individually hook the tab at the gap. The panels are assembled into geometric structures having flat or curved faces.

A jigsaw puzzle kit is provided having a plurality of interlocking puzzle pieces configured for assembly to form a three dimensional image, each puzzle piece having a surface an image applied thereon, a resilient layer for generating a tactile response when the puzzle piece is depressed, and a rigid backing layer below the resilient layer for providing support. Also provided is a method of manufacturing a jigsaw puzzle which includes the steps of applying an image onto the surface of a resilient material; applying a mold to the resilient material so as to create variations in the height of the resilient layer; adhering a rigid backing material to the molded resilient material; and die cutting the resilient material and the rigid backing material to create a plurality of interlocking puzzle pieces.
