An illuminated game piece, such as a die or dice in which an electrical circuit powering a light source are encapsulated by a material forming a body of the game piece. The electrical circuit includes an inductive charging coil, an energy storage device and at least one illumination device. The inductive charging coil may be coupled to an inductive charger to replenish the energy storage device. When encapsulated, there are no ports or external connectors and the integrity of the game piece is assured so that is no change in game play.

A handheld electronic game includes a housing assembly; resilient domes protruding from the housing assembly; and a programmable, interactive system and at least one light emitting diode mounted within the housing, electrically connected to the programmable, interactive system. The housing assembly has a front housing portion and a rear housing portion. Each of the domes has a first surface and a second surface. The domes can transition from a first position where the first surface is convex to a second position where the second surface is convex. The programmable, interactive system includes a microprocessor and a sensor. The sensor is electrically connected to the microprocessor and senses when one or more of the domes transitions from the first position to the second position or from the second position to the first position. The domes can be returned to their first position with a reset mechanism or manually.

Disclosed are a smart spindle with a replaceable battery, and a smart Rubik's cube. The smart spindle comprises a core (100), a sensor (200) and a main control module (310), wherein the core (100) comprises a housing (110) with a cavity (111); the main control module (310) is mounted inside the cavity (111); the sensor (200) is electrically connected to the main control module (310); the sensor (200) is mounted at the core (100); the cavity (111) is also used for mounting a battery (400), the housing (110) is provided with a notch (112) for having access to the battery (400), and the notch (112) is in communication with the cavity (111); or, the exterior of the housing (110) is used for mounting the battery (400), and the housing (110) is provided with a through hole (113), such that the cavity (111) is in communication with the exterior of the housing (110) via the through hole (113). 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 electronic tag game assembly includes a plurality of bracelets that is each worn on a wrist of a respective one of a plurality of players of the game of tag. The plurality of bracelets includes a trigger bracelet worn by the player that is it and a set of receiver bracelets each worn by players that are not it. A plurality of tracking units is each coupled to a respective one of the bracelets. The tracking unit on the trigger bracelet is actuatable in a first condition indicating the player wearing the trigger bracelet is it. The tracking unit in each of the receiver bracelets is acuated into the first condition when the tracking unit in the trigger bracelet moves within a trigger distance of the tracking unit in any of the receiver bracelets. In this way the tracking units communicate a visual alert for the game of tag.

What is disclosed is a mobile freewheeling playing card cart. The cart has a tray positioned upon a rolling base that is capable of holding two or more stacks of playing cards. The tray features barriers and depressions around the card stacks that make the cards more easily accessible. The cart includes one or more handles used to maneuver the cart. The cart may be motorized through the use of an integrated battery and remote control.
