Abstract: A jigsaw puzzle has a blank and computer-printable face. The jigsaw puzzle has a thick substrate which forms a thick substrate sheet. The thick substrate sheet has been die-cut, into thick puzzle pieces. The thick puzzle pieces are joined together by uncut lands between the thick puzzle pieces. The cuts and said lands are in such proportions as to allow users to separate the thick puzzle pieces from each other. The thick substrate is at least 0.020? thick.

Abstract: A puzzle for printing on a printer having rollers in its paper feed path, such as a personal computer printer. The puzzle is a semirigid but flexible sheet having at least one blank side serving as means for printing on by the printer. The sheet is sufficiently flexible to negotiate through the rollers of the printer. The sheet has a plurality of die-cuts defining pieces. The die-cuts intersect at intersections. The intersections have nicks for separating each cut at its intersection, and for maintaining rigidity of the sheet during printing.
