A teaching aid for binary programming language contains: a Rubik's cube including six surfaces. Each side has fourth corner pieces, four side pieces, and a center piece which are rotatable. Each of the four side pieces is defined among any two adjacent corner pieces and the center piece, and the center piece is defined among the four corner pieces and the four side pieces. The center piece has a calculation sign, and each of the fourth corner pieces and the four side pieces has a binary number.

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.

The present invention provides a magic cube timing device based on Bluetooth communication, including a timer main body and a non-slip mat. The timer main body is fastened to the non-slip mat. The timer main body includes a main body housing, a main control PCB board, a display apparatus, and two magnetic surface stickers. Two through holes are disposed in the main body housing. One end of the magnetic surface sticker penetrates through the through hole to connect to the main control PCB board. According to the magic cube timing device based on Bluetooth communication in the present invention, each use result in the magic cube timing device is transmitted to an external terminal by using a Bluetooth module, to effectively collect statistics on and store timing data.

According to another aspect, a method of determining a current state of a cubic puzzle independent of information concerning a prior state of the cubic puzzle using at least one RGB sensor. With the cubic puzzle maintained in a first state, (a) illuminating a first colored surface selected from the plurality of colored surfaces with a single source of light selected from the plurality of sources of light because of an association with the first colored surface and sensing a color of the first colored surface with the RGB sensor when the first colored surface is illuminated. Repeating act (a) by separately illuminating each of the plurality of colored surfaces with a respective single source of light selected from the plurality of sources of light because of an association between the respective single source of light and the respective colored surface that is being illuminated, and act of processing the colors sensed by the RGB sensor at each of the preceding acts to determine a location and orientation of each of the plurality of tiles with the cubic puzzle in the first state.

My invention is a puzzle game that is used for entertainment purposes. The game is played on a puzzle cube with cards and window cling markers as additional pieces to the game. The object of the game is for the first person to get all their numbers in a row on the puzzle cube to win. I wanted to still have the fun and excitement of how we have played bingo in the past with a twist. By improving this game it will help to meet the needs of our game players who enjoy bingo.

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.

A magic cube with visible magnetic cabins includes a central shaft piece, six central blocks, eight corner blocks, and twelve edge blocks. Corner block magnetic cabins and edge block magnetic cabins are respectively arranged on the corner blocks and the edge blocks. Magnets and magnetic pieces are respectively arranged in the corner block magnetic cabins and the edge block magnetic cabins. Elastic force between the central blocks and the central shaft piece is adjusted by gear adjusting pieces arranged in the central blocks. By arranging the corner block and edge block magnetic cabins, stability of installation positions of the magnets and magnetic pieces is ensured and an assembly accuracy is improved. The magnetic pieces do not fall off or offset during use. By arranging the gear adjusting pieces in the central blocks, it is convenient to quickly adjust elastic force between the central blocks and the central shaft piece.

The present invention provides a cubic puzzle which is capable of changing its entire body into a cubic block shape ad has an improved entertainment property as a toy. A controller automatically changes a display pattern to a reference pattern by an actuator, making it a minimum condition that a current pattern being a display pattern at that point of time when identified by a pattern identifying means is different from a reference pattern being a predetermined reference display pattern, while a start state detecting means detects a predetermined start state.

Disclosed herein are embodiments of three-dimensional puzzles that implement image sensors to read signatures of individual shell segments to thereby determine shell segment patterns. Also disclosed are embodiments of systems that implement RGB sensors adjacent gradient color maps to provide contactless absolute position encoders.
