Abstract (en)
A three-dimensional and spherical jigsaw puzzle includes multiple identical pieces (10). Each piece (10) has a thickness defined by a lower contour and an upper contour. A radius of the spherical jigsaw puzzle passes through the lower contour and the upper contour so that the thickness of the piece is tapered. A quantity of the sides of each piece may be odd and each side has a shape the same as a shape of the other sides. <IMAGE>
