A game court with improved and adjustable back bumper may feature a back bumper pivotably attached by a band to an interlocking member of the playing court. The bumper may then have a reactive nature to contact by a rolling ball in play. Sliding locks may be utilized to lessen, or even eliminate, the reactive nature of the bumper.

A puzzle system includes a flexible plate having cavities of arbitrary shapes, a stiffener structure, and flexible puzzle pieces which are also of arbitrary shapes. The thickness of the puzzle pieces is equal to or greater than the depth of the cavities. The shape of at least one of the puzzle pieces substantially matches the shape of at least one of the cavities. The flexible plate and the flexible puzzle pieces may further include embossing, debossing, and/or imprints.

Provided is a game system with gears and indicia, for modular game information record-keeping and record-changing devices, systems, and associated methods based on sets of mechanical gears having game indicia provided thereon. The architecture of the system uses combinations of mechanical gears, cams, shafts, clutches of various types, and other mechanical components that constitute an analog “computer” performing basic mathematical functions, managing data, or performing analogs for life principles - such as the impact of events, physics-based or fantasized realities, interpersonal relationships, behavioral characteristics, conflict dynamics, etc.

A device (10) for flipping stacked cards from a first position to an opposite second position, the device comprising a flexible hollow cup-shaped member (12) having a base portion (13) defining a rim (14), and at least one recess (15) or aperture formed in or proximate a portion of the rim so that when the base portion is placed on a generally flat surface (16), there is formed at least one opening (17) that allows air to pass through when pressure is applied to an outer surface of the cup-shaped member

A game apparatus includes a first total number of playing-pieces and an article of manufacture including: a grid structure which is sufficiently flexible so as to be substantially conformable to a surface of a substrate on which the grid structure is disposable; apertures in the grid structure exposing corresponding portions of the surface of the substrate on which the grid structure is disposable; areas of the apertures being sized to accommodate corresponding playing-pieces of a game; and a second total number of the apertures being sufficient to accommodate the first total number of the playing-pieces.

The present invention discloses a surface orientation sensing structure, where six printed circuit boards are combined to form a regular hexahedron as the axis of an intelligent magic cube, and a main control chipset can recognize layer rotation by simply sweeping a copper foil through a brush sheet to cause a level change, so that the position change of the layer can be recognized more accurately, a step loss rate is reduced, parts are reduced, and the assembly process is simplified. The present invention further discloses an intelligent magic cube, where all the parts related to orientation sensing are concentrated on the axis, so that the intelligent magic cube can be operated more easily and smoothly, the intelligent functions of the intelligent magic cube can be used more smoothly, and user experience is improved.

The present invention provides a connecting structure for plate members, including a projection projected from one of the plate members in a first direction, and a groove provided on the other of the plate members to have inner faces facing each other in a second direction intersecting the first direction and configured to fittingly receive the projection. The projection includes a main body, a resilient portion provided on one side of the main body in the second direction and resiliently inwardly deformable in the second direction, and an engagement portion outwardly expanded in the second direction from the resilient portion and configured to be plastically deformed along and engage with one of the inner faces of the groove when the groove fittingly receives the projection.

A collapsible, self-expanding polyhedron comprises a plurality of side members each connected with an elastic band that is sized to urge each side wall of adjacent side members together to form an expanded configuration. When the polyhedron is compressed on two opposing side members, which causes the other side members to separate into a collapsed configuration, the elastic band expands to a maximum length with maximum tension. Once the compression is released, the at least one elastic band retracts back to a minimum length and urges the side members back into the expanded configuration.

A device includes a pad having an outermost upper surface for receiving a hand strike and an outermost bottom surface defining a recess extending upward into the pad and defining a central interior space of the pad; a base removably attached to the pad in covering relation to the recess defined in the bottom surface so as to close off the central interior space; and an electronics module located within the central interior space. The electronics module preferably is configured to detect a hand strike received on the outermost upper surface of the pad and play through a speaker, upon the detection of the hand strike, an audio response. The electronics module includes a sensor for detecting the hand strike. The sense may be an accelerometer or vibration sensor. Additional embodiments of the device also are disclosed.
