To provide a means easily rotating each polyhedron even if superimposing respective polyhedrons by easily moving the rotary shafts of the polyhedrons.

In conventional picture-matching toys such as a jigsaw puzzle, 'hukuwarai', and a dress-up doll, pictures are matched with each other by fitted in, placed on, or replaced. However, screens are limited in the plane and in a rotation type, the rotary shaft is fixed so that the rotation of superimposed polyhedrons cannot be performed easily. Screens and parts are also divided. Therefore, the screens are also set to polyhedron types and superimposed so that the screens are increased and easily rotated, thereby easily changing the screens and facilitating the picture-matching. When regarding pictures and letters except for the screen as parts, the parts also become integrated type.
