A spherical puzzle includes a portable body having a central core, a plurality of co-extensively shaped sections rotatably disposed about the central core, a plurality of locking mechanisms associated with the sections, respectively, and a plurality of hemispherical travel paths configured about the body. Advantageously, the sections are dynamically configured to freely rotate along the hemispherical travel paths to create a desired pattern. In this manner, locking mechanisms slidably engage the sections such that each section remain rotatably aligned along the hemispherical travel paths and about the central core.

The present invention relates to a novel puzzle system that includes an interactive cube puzzle game and methods of use. It provides a puzzle game concept that is implemented as a three-dimensional game or a two-dimensional game, in which a user achieves success by matching a target pattern based on manipulation of identifiable elements. It comprises a plurality of connected elements, a plurality of identifiable elements, a plurality of user interface elements and is configured to operate based on the transition of the plurality of the identifiable elements from a first position to a second position to obtain a target pattern. The transition from the first position to the second position includes variation in the plurality of the identifiable elements.

Disclosed herein is the 3-D puzzle implemented as a cube consisting of eight movable sectors configured to move about a central cross-piece created by three axels that are perpendicular to each other. Each movable sector includes three movable elements positioned orthogonally to each other. Each movable element has an outer edge surface attached to a holder. The holders of the three movable elements form a central cross inside the movable sector. The central cross allows the three movable elements to assume positions where the movable element is extracted or retracted relative to the hosting movable sector. Each holder of the movable element has a magnet positioned inside. The central piece of the 3-D cubical puzzle is formed by a central cross made of three orthogonal axes with flat ends configured to fix the movable elements in a static position and to move from one static position into another.

A smart center shaft, a smart Rubik's Cube, and a timing method therefor. The smart center shaft comprises a core, a sensor, and a master control module. The core comprises a housing having a cavity. The sensor is mounted on the core. The sensor comprises a stator and a rotor. The stator is fixed on the housing. The rotor is configured to be connected and rotate simultaneously with a Rubik's Cube layer of the smart Rubik's Cube, thus allowing the rotor to rotate with the Rubik's Cube layer relative to the stator. The master control module is mounted within the cavity. The master control module is electrically connected to the sensor. The master control module acquires a rotation signal of the Rubik's Cube layer on the basis of the relative rotation between the rotor and the stator. The sensor and the core form one integral body, the degree of integration is high, and the consideration of complex assembly relations between the stator and a center block or an intermediate connecting block is avoided.

Disclosed are a smart spindle with a replaceable battery, and a smart Rubik's cube. The smart spindle comprises a core, a sensor and a main control module, wherein the core comprises a housing with a cavity; the main control module is mounted inside the cavity; the sensor is electrically connected to the main control module; the sensor is mounted at the core; the cavity is also used for mounting a battery, the housing is provided with a notch for having access to the battery, and the notch is in communication with the cavity; or, the exterior of the housing is used for mounting the battery, and the housing is provided with a through hole, such that the cavity is in communication with the exterior of the housing via the through hole. When the power for the smart Rubik's cube is insufficient, a player can remove the used battery and replace same with a fresh battery, such that the smart Rubik's cube can continue to be used immediately, without the need to perform charging and the need to stop use for a period of time, thereby facilitating the use by the player.

An electronic device with a transformable multi-planar display includes a central body and peripheral elements. Each peripheral element has outward-facing sides and inward-facing sides. Each outward-facing side comprises a microprocessor-controllable electronic display screen. Each inward-facing side includes a contact group of electrical contacts arranged to engage with another contact group of electrical contacts of another other one of the peripheral elements. Each contact group includes a plurality of permanent magnets, a plurality of sockets recessed in a corresponding inward-facing side, each socket defining a cavity that houses a corresponding permanent magnet and has an aperture through which at least a portion of the housed permanent magnet is permitted to protrude. A retention spring is situated within each socket and coupled to the housed permanent magnet. The retention spring exerts a biasing force to retain the permanent magnet in a recessed position when there is no engagement with another contact group.

Connector element includes an enclosure made of a generally non-magnetic material having an open face; an insulating plate with a plate aperture; a permanent magnet placed inside the enclosure, the magnet dimensions preventing egress from the enclosure through the plate aperture; a washer made of a conductive soft ferromagnetic material with a washer aperture being larger than dimensions of said permanent magnet, placed inside the enclosure. Also disclosed are transformable electronic devices, optionally including displays, toys and educational kits built using the self-actuating connector elements.

The present invention relates to three-dimensional puzzles with segments capable of changing position in relation to one another, said segments having guides for allowing the movement of movable elements. According to the invention, the movable elements are configured in the form of permanent magnets, wherein the movement of each magnet is limited by its own guide, and each magnet is capable of being positioned in at least one of two end positions, wherein the guides in the movable segments are arranged to allow different magnets to interact with one another and to change position relative to movable elements. Movement of the magnets is provided by both the attraction and the repulsion of different magnets. The technical problem addressed is that of increasing the existing assortment of puzzles having movable segments.

The present invention relates to a smart magic cube providing a cube game by changing lights of respective cells constituting a magic cube while the cells are fixed, and an operation method thereof. A smart magic cube of the present invention includes: a cube housing in which each surface is divided by N×N cells; a light emitting part formed inside each cell and emitting at least one type of light externally through a surface of the cell; six rotation means formed in a rotatable manner; a rotation sensing part sensing a rotation direction and a rotation angle of the rotation means; and a control part controlling the light emitting part to change and emit lights such that border cells of a surface where the rotated rotation means is formed, and cells of four different surfaces adjacent to the border cells output lights changed according to a preset rule.
