) being adjacent to one another and attached to an outer periphery of the core (
50
) to form a globe. For stand the globe, the conventional jigsaw puzzle further comprises a stand (

Multiple puzzle pieces are detachably adhered to an outer periphery of the hollow core and each has a curvature equal to that of the hollow core for completely covering the outer periphery of the hollow core. Each puzzle piece defines at least one concave portion and forms at least one convex portion laterally extending from each of the multiple puzzle pieces. Each concave portion receives a corresponding convex portion of an adjacent puzzle piece such that the multiple puzzle pieces are connected to one another.
