The invention comprises a continuous surface made from jigsaw puzzle pieces, wherein the three or more pieces whose corners share a common point when assembled, have corner angles whose sum is less than 360 degrees with the common point as vertex of said corner angles. The present invention makes it possible to work on jigsaw puzzles which, when assembled and during assembly, form continuously curving polyhedral surfaces, and to provide a jigsaw puzzle whose pieces assemble edge to edge into a self-supporting curved surface which is a closed multifaceted polyhedron whose appearance is substantially spherical.
