Abstract:
1. A puzzle set for electrically announcing a proper solving of a two-dimensional jigsaw puzzle, the puzzle set comprising: a plurality of inter engageable puzzle pieces, each having front and rear planar surfaces and one or more side surfaces, which can be assembled together into a one assembled puzzle revealing an image, said front surface of each of said puzzle pieces comprising a part of the image which is shown as a whole in the assembled puzzle; a frame configured to surround said puzzle pieces having a raised peripheral rim and a bottom wall defining a well therewith having a planar plate for receiving a partially or fully assembled jigsaw puzzle; each of said puzzle pieces comprising two electrically connected conductive pads attached to said one or more side surfaces, so that when assembled together said pads of adjacent puzzle pieces are in contact such that an assembly of said plurality of puzzle pieces forms a continuous conductive path; an annunciator in said frame for announcing using visual or audible signaling, wherein said annunciator comprises a time metering device coupled to the conductive path to stop counting upon forming the conductive path to measure the puzzle assembly time and to display the counted time; and a power source for powering said annunciator; wherein the proper solving of the puzzle forms an electric circuit so that electrical current flows from said power source via said conductive path to said annunciator for activating thereof.
