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.

A wireless powered luminous puzzle is provided, which includes a positioning base plate and several puzzle modules; each puzzle modules includes: a PVC board, a paper board, and a TPE board; an interior of the paper board is embedded with a LED module; an interior of the positioning base plate is provided with a power supply circuit; the power supply circuit is inductively connected to the LED module. In summary, the present application provides a luminous puzzle that can be induced by a wireless coil to emit light from puzzle blocks. Compared with a luminous puzzle in existing technology, the present application effectively protects the PCB inside the puzzle module by embedding the LED module into the paper board of the puzzle module, improves a seismic performance of the puzzle module, and avoid loosening and damage of the LED module.

A user-customizable audio-visual puzzle includes a platform having a base layer, a middle layer, and a top layer coupled together. The middle layer includes a first cavity therein. The top layer includes at least one cutout therethrough. The puzzle further includes at least one puzzle piece having a peripheral configuration shaped to correspond to the at least one cutout in the top layer. A drawer is configured to be removably positionable within the first cavity of the middle layer. The drawer includes at least one second cavity configured to be positioned generally beneath the at least one cutout when the drawer is positioned within the first cavity. The puzzle also includes a recording system configured to record a message associated with the at least one cutout.

The present invention relates to a puzzle system capable of cooperating with an external device. More specifically, it relates to a puzzle system capable of cooperating with an external device, whereby a user's continuous interest can be stimulated by automatically detecting a type of puzzle that includes a plurality of puzzle pieces, and expressing various implementation operations corresponding to the puzzle when the puzzle is completed. To this end, the present invention includes: a puzzle device for transmitting a detection signal by detecting the completion of placement of a plurality of puzzle pieces forming a puzzle; and an implementation device operating in response to the signal transmitted from the puzzle device, wherein the puzzle device includes: a frame having a placement face on which the plurality of puzzle pieces is placed; a detection module for detecting the completion of placement of the puzzle pieces; and a main communication module for transmitting a signal detected at the detection module.
