PROBLEM TO BE SOLVED: To provide a three-dimensional puzzle in which a portion of a magnet can easily be removed from pieces of the three-dimensional puzzle or mounted thereon and an appearance shape can be created in conformity to user's preference.SOLUTION: A three-dimensional puzzle comprises: a magnetically attractable sphere 3; and a plurality of wood pieces 2 disposed so as to cover the sphere 3 in response to an area surrounded by a division position over the warp direction and a division position over the weft direction of the sphere 3, and enabled to move around the sphere 3 in a magnetically attached state. A magnet 4 is a plastic magnet, and comprises: a spherical surface-shaped plate section 5 with one side of the sphere 3 side conformed to a surface shape; and a boss section 7 projected from the other one side of this spherical surface-shaped plate section 5, inserted into a boss hole 6 drilled to the wood piece 2, and capable of being increased in diameter. Diameter enlargement means 11 for expanding or shrinking the boss section 7 in a boss radial direction is attached to the boss section 7, and inserted into the boss hole 6 of the wood piece 2. The magnet 4 is detachably mounted to the wood piece 2 through the boss section 7 increased in the diameter by the diameter enlargement means 11.SELECTED DRAWING: Figure 9 |
