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.

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.

An intelligent magic cube, and a sensing shaft center structure and a timing method used thereby. The sensing shaft center structure comprises a main body; the main body comprises a core (1) having an internal cavity, and several tubular shafts (2) communicated with the core (1). An internal central control module (3) is provided inside the cavity, and comprises a state obtaining unit. Each tubular shaft (2) is provided with a state signal sending set (4). The state signal sending set (4) comprises a signal selector and multiple signal exciters. The signal selector may be paired with any signal exciter, and generate a corresponding state signal. The state obtaining unit is configured to be able to receive the state signal sent from the state signal sending set (4).

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.
