[0063] Optionally, the spherical shell 171 can be provided with magnet fixing slots 175 for fixing magnets. Each second corner piece 12 corresponds to a magnet fixing slot 175, and the magnet is placed in the magnet fixing slot 175. When rotating the Rubik's Cube, rotating one layer of the cube by 90° changes the magnetic attraction position of the second corner piece 12, causing it to attract another magnet on the spherical shell 171, thus detaching from its original position and then repositioning it, completing one action. This action is repeated until the entire Rubik's Cube is solved. Because the magnets are located inside the Rubik's Cube, the movement distance of the corner piece's magnetic adjustment lever is very small. Therefore, even a small internal rotation angle will result in the piece being attracted by the magnetic force of the other magnet on the spherical shell 171, achieving automatic return and positioning at large angles.

[0064] In one embodiment, the magnetic adjustment module may include a corner block magnetic adjustment dial 124, a corner block adjustment upper dial 123, and a corner block adjustment lower dial 125. A platform for placing the corner block adjustment lower dial 125 is provided on the side of the second corner block bottom shell 122 away from the spherical shell 171. The corner block adjustment upper dial 123 is located on the side of the corner block adjustment lower dial 125 away from the second corner block bottom shell 122. Stepped magnetic adjustment teeth 126 are provided on the opposite sides of the corner block adjustment upper dial 123 and the corner block adjustment lower dial 125, enabling meshing connection between them. A protrusion for fixing the corner block adjustment disk is provided on the side of the corner block adjustment upper dial 123 away from the corner block adjustment lower dial 125, and a corresponding recess is provided on one side of the corner block adjustment disk. The corner block adjustment disk and the corner block adjustment upper disk 123 are relatively fixed by the cooperation between the convex and concave points.

[0065] Optionally, the corner block adjustment disk has a through hole in the middle corresponding to the corner block adjustment upper disk, through which a portion of the corner block adjustment upper disk 123 is exposed. The second corner block bottom shell 122 has a corner block fixing post, which passes through the corner block adjustment lower disk 125 and the corner block adjustment upper disk 123 in sequence and is fixedly connected to the second corner block shell 121. The corner block adjustment lower disk 125 can be a ring structure. The corner block adjustment disk has a gear adjustment hole. The area of ​​the corner block adjustment lower disk 125 not covered by the corner block adjustment upper disk 123 has a protruding structure. The protruding structure is opposite to the gear adjustment hole and inserted into the gear adjustment hole to achieve relative fixation between the corner block adjustment dial 124 and the corner block adjustment lower disk 125. The gear adjustment tool 19, used to adjust the magnetic force level, contacts the corner block magnetic adjustment dial 124 and moves it to change the engagement state of the lower corner block adjustment plate 125 and the upper corner block adjustment plate 123, thereby adjusting the distance between the corner block magnetic adjustment rod and the magnet on the ball shell 171. Specifically, six magnetic force levels can be adjusted using the gear adjustment tool 19.
