The jigsaw puzzle includes a baseplate used with attachable puzzle pieces. The baseplate has multiple upward-facing engagement mechanisms that are engaged with corresponding and complementary puzzle piece rear-facing engagement mechanisms. The rear-facing engagement mechanisms and the complementary puzzle piece rear-facing engagement mechanisms are designed so as to leave a space between the bottom of the puzzle piece and the top surface of the baseplate to facilitate removal of the puzzle pieces. An optional pry tool can be inserted in to the space to easily remove the puzzle pieces after play, storage, or display. An optional hanger/joiner can be utilized to hang the completed puzzle vertically and/or to join two baseplates to create increased play opportunities.

The set consists of smaller elements which complement one another in shape like jigsaw puzzle pieces in such a way that, being interconnected by circular dovetail type connectors situated on the edges, they fill up a larger area of a circular geometric figure. It consists of a central element (1,1a) and many concentric ring-shaped sectors (2 a, 2b, 2h) which, selected according to the radii (r1, r2) and the central angle (co) are interconnected by dovetails (3) on radially oriented edges, forming at least two ring-shaped fields including the central element (1,1a).

A puzzle comprising a set of puzzle pieces and a puzzle assembly surface having a puzzle assembly image printed thereon, the image includes blank areas corresponding to sections of a source image and background puzzle image corresponding to complementary sections of the source image. Each of the puzzles has an image printed on it that corresponds to a particular region of the source image. Shape and size of the puzzle pieces and the images printed on them are such that, when each puzzle piece is placed on the puzzle assembly surface in a particular position with a particular orientation covering a particular blank areas and a portion of the background puzzle image directly surrounding the blank area, a region of the background puzzle image that remains uncovered by the puzzle piece is complementary to the image printed thereon. Thereby, when all puzzle pieces are placed on the puzzle assembly surface in their corresponding positions with corresponding orientations, each covering corresponding blank area, the images printed on the puzzle pieces together with the regions of the background puzzle image that are left uncovered by the puzzle pieces form an image that is generally identical to the source image.

A rotating assembly and a movable puzzle platform using the same are disclosed in present invention. The movable puzzle platform includes a board assembly having a puzzle board, a kickstand pivotally coupled at the board assembly and the rotating assembly attached on the kickstand and having a first moving member, a second moving member rotatably coupled to the first moving member for forming a holding space and a plurality of ball bearings rotatably received in the holding space for allowing the second moving member rotating with respect to the first moving member. One end of the kickstand is pivotally coupled at the board assembly while a free end of the kickstand is adapted to pivotally fold from the board assembly.

A puzzle platform includes two puzzle drawers, a puzzle board and a support assembly configured to support the puzzle board and having a receiving space cooperatively with the puzzle board. The support assembly includes a supporting member having a top wall, a partition wall configured to forming a pair of openings communicated with the receiving space cooperatively with the top wall. Each of the puzzle drawers is actuated to slide in-and-out of the receiving space through the openings. The partition wall is integral with the top wall, so that the manufacture of the puzzle platform is simple and low-cost.

System and method for additional amusement, entertaining and surprising visual or audible reward provided upon completing the reconstructing of a two-dimensional or three-dimensional jigsaw puzzle. The puzzle pieces include conductive pads connected by a conductor such as a wire, a metallic strip or a conductive paint, so that upon assembling the puzzle, the pads are in contact to form a continuous conductive path. The frame or the puzzle pieces include a battery (or an AC adapter) and a visual or audible signaling device operating upon sensing the continuity of the conductive path. Each of the puzzle pieces may include three or more conductive pads, allowing for the forming two or more isolated or connected distinct conductive paths. The conductive path can further affect a time measurement and its related display for timing the puzzle solving.

The puzzle with attachable and releasable pieces includes shaped puzzle pieces and a two-part base, which includes a front base section and a back baseplate. The puzzle pieces have rear-facing engaging mechanisms that are attachable to forward-facing male studs carried by the back baseplate. The puzzle pieces each have a particular outer shape determining placement. The puzzle may be stored with the puzzle pieces engaged to the back baseplate, but the puzzle pieces may be later released for repeat play by using a provided puzzle release mechanism.

A figure for attaching to a building block includes a body; and a base attached to the body at a first end of the base, the base has a cavity disposed within a second end of the base to slidingly attach to one or more connectors of the building block; the figure is detachably mounted on the building block.
