Abstract: The present invention and creation relates to a kind of jigsaw puzzle and its method of fabrication. The jigsaw puzzle is comprised of a plurality of jigsaw puzzle blocks through cutting of a jigsaw puzzle board. The said jigsaw puzzle blocks are disposed of arc surfaces on the edges of both sides. In the jigsaw puzzle, the edges of both sides are arc surface, easy for splicing of jigsaw puzzle blocks. Also, the edges of the jigsaw puzzle blocks uneasily result in injury, which are safe in use. In method for fabrication of jigsaw puzzle, two sets of tools are used to be symmetrically provided on both sides of the said jigsaw puzzle board. The said two sets of tool move reversely, pressing and cutting the said jigsaw puzzle board to form a plurality of jigsaw puzzle blocks, as a result, the fabricated edges on both sides of the jigsaw puzzle blocks are arc surface.
