  • Patent number: 5439221
    Abstract: A puzzle game such as a jigsaw has a number of interfitting pieces which combine to create a finished visual effect. A number of the pieces, e.g. in an area of a single color or pattern, can be positioned interchangeably as regards the visual effect. At least some of these interchangeable pieces carry markers enabling their disposition to be determined. For example, the markers may be metal spots whose layout can be determined by scanning using radiation. A particular use of such a puzzle game is in a competition or lottery based on chance, where a number of completed puzzles are submitted for comparison with a standard "solution" layout involving a specific arrangement of the interchangeable pieces.
