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 gradually revealing an image using cube puzzles is provided. A first image is divided into a plurality of blocks. Each block can have one or more arbitrary colors. A second image is then generated from the first image where each block of the second image corresponds to one or more blocks of the first image. The blocks of the second image are unicolor blocks with colors that are selected from one of the six colors of a cube puzzle. Groups of adjacent blocks of the second image with the same number of rows and columns as the sides of the cube puzzles are assigned to participants to match to the color of the blocks on the sides of their cube puzzles. Once each participant matches the colors of an assigned region on a side of the corresponding cube puzzle, the matched region is reveled to all participants.

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.

A logic cube for teaching, learning, entertainment and motivation is presented. The logic cube has indicia arranged in well-defined orientations including radial symmetry, pairing pattern and triple logic. The pairing pattern helps to generate meaningful combinations for applications involving sets of two (2). The triple logic helps to generate meaningful combinations for applications involving sets of three (3). Radial symmetry helps generate meaningful combinations involving a greater number of indicia. Applying the exclusion logic helps to avoid meaningless or undesirable combinations and ambigrams help to include indicia which can be read in multiple orientations. The invention of logic cube provides a new function which can be applied to numerous areas such as science, arts, food, fashion, motivation and general education and it provides a novel experience as compared to prior art. The invention of logic cube could be applied to other geometric shapes such as tetrahedron (Pyraminx®) and dodecahedron (Megaminx®) and sizes other than 3×3×3.
