A transformational toy comprises at least six polyhedron bodies, at least one connection strip for connecting the polyhedron bodies in a chain, wherein the connection strip provides hinges between every pair of adjacent polyhedron bodies of the chain, wherein the hinges facilitate movement of the polyhedron bodies between at least two different geometric transformations of a combined body of all polyhedron bodies, wherein at least one of the connection strips is connecting at least three adjacent polyhedron bodies.

A sliding intelligence toy including a housing, two fixed pads fixed at two inner ends of the housing, a movable pad located between the two fixed pads, a connecting shaft structure passing through the two fixed pads and the movable pad, a first block structure and a second block structure. One end of the connecting shaft structure sticks out from one end of the housing and can move along the axial direction of the housing and rotate along the radial direction of the housing under the action of an external force, and the movable pad can rotate with the rotation of the connecting shaft structure. The sliding intelligent toy has a simple game principle, can be operated easily and flexibly and set clear levels of difficulty, which is challenging.
