Abstract:
A tier-on-tier multiple level jigsaw puzzle comprised of varying thickness and irregular interlocking pieces which, when assembled, form an image with visible surfaces in relief relative to the tabular surface. The puzzle is formed of a lower, base puzzle and an upper puzzle, which when combined have variable distinct surfaces and variable thickness with planar and/or textured surfaces to result in a raised relief 3D effect. The specific mix of individual pieces exhibiting variable thicknesses & distinct surfaces enhances enjoyment by adding strategic elements to puzzle assembly and optimizes the quality of the image.
