A game piece assembly includes: a front surface formed in a first predetermined shape and including a predetermined number of pips, a back surface formed in a second predetermined shape, a side surface extending between the front and back surfaces, wherein the front surface, the back surface and the side surface define a hollow space that is configured to hold a prize therein in a closed configuration.

A 3-dimensional logic game has a support structure, an actuating structure attached to the support structure and game elements attached to the actuating structure. The game elements are formed as carriages provided with first and second marking surfaces and are slidably mounted on rails attached to the actuating structure. The actuating structure is movable between a first and a second rest position. In the first rest position, a first group of three rails form first rail rings around vertices of a first tetrahedron wherein the first marking surfaces of the carriages are facing outwardly, while the second marking surfaces are facing inwardly. In the second rest position, a second group of three rails form second rail rings around vertices of a second tetrahedron while in the point reflection of the first tetrahedron reflected over the geometric centre thereof.

A method of teaching and learning using a game of random selection wherein each student in a group of students takes a turn to catch an object in a container with a fishing pole. The object caught in the container is pulled out of the container. The student identifies the indicia on the object to the group of students, wherein indicia include letters, words, numbers, colors, and shapes. If the student makes a correct identification, the student retains the object. A teacher provides a reward to the student based on the number of objects identified correctly. The teacher can identify students with insufficient success in identifying indicia correctly and can have these students practice the game of random selection to improve retention of the correct identifications of the indicia. Students can move around and interact with each other while learning and having fun, while retention of learned subject matter is being reinforced.

A magnetic levitation magic cube includes edge blocks, corner blocks and center blocks. Inner sides of two side faces close to the corner blocks of the edge block each are provided with three magnet mounting grooves, and a magnet is mounted in each of the magnet mounting grooves. The center block includes a center block body and a center block cover. The center block cover covers and is spliced to the opening of the center block body. The center block further includes an upper magnetic disk and a lower magnetic disk. The upper magnetic disk is provided with a through-hole for fastening a central shaft of the magic cube. The lower magnetic disk is provided with a through-hole for the central shaft of the magic cube to pass through. Two repelling annular magnets are fixedly mounted in each of the upper magnetic disk and the lower magnetic disk.

A smart magic cube and sensor used thereby, a smart center shaft, and a monitoring method. A sensor includes a stator, a first rotor, and a second rotor. The stator is fixedly provided on the smart magic cube. The first rotor is configured to be able to rotate synchronously with a first magic cube layer, such that when the first rotor rotates with respect to the stator along with the first magic cube layer, the stator or the first rotor can output a rotation signal of the first magic cube layer; and the second rotor is configured to be able to rotate synchronously with a second magic cube layer, such that when the second rotor rotates with respect to the stator along with the second magic cube layer, the stator or the second rotor can output a rotation signal of the second magic cube layer. By using the structure of “one stator and two rotors”, the sensor implements detecting the rotation signals of “the two magic cube layers” of the smart magic cube, thereby facilitating obtaining a state signal of the smart magic cube in a next step.
