A cross-shaped billiards rack is disclosed. The cross-shaped billiards rack allows players to use a standard billiard table, with standard object balls and cue balls, and play a variation of billiards. A variety of methods for playing billiard games with the cross-shaped rack are disclosed. The cross-shaped billiards rack can be used to form a 9-ball cross; a 5-ball mini-cross; or a 7-ball unbalanced cross.

A pool table capable of avoiding ball bounce, including a playing field and a rail structure mounted along an edge thereof. The rail structure includes a steel rail and a rubber strip mounted at an inner side thereof. A ratio of height difference H between top surfaces of the rubber strip and the playing field to diameter D of a billiard ball is 0.68-0.74. A position of the rubber strip in contact with the billiard ball is configured as a striking point. A coordinate system is established with a center of the billiard ball as origin, a horizontal line passing through the origin as abscissa axis, and a vertical line passing through the origin as ordinate axis. The striking point is higher than the center of the billiard ball. An angle between a line connecting the origin to the striking point and the abscissa axis is 2-8.

A billiard chalking assembly for applying billiard chalk to a billiard cue includes bracelet that is worn around a wrist. A ball is provided and a billiard chalk is positioned in the ball. The ball is removably coupled to the bracelet thereby facilitating the billiard chalk to be accessible to a wearer of the bracelet. The ball is manipulated to facilitating the billiard chalk to chalk a billiard cue.

A billiard table top lighting apparatus provides substantially uniform lighting across the surface of a billiard table surface. The frame may support one or more cameras, one or more motion sensors, one or more microphones, and/or one or more computing devices to enable any of a variety of innovative features. Such features could include automatic game play recording from one or more perspectives, merged video track storage for replay, review, and analysis, automatic lighting and dimming control, control of the apparatus from any mobile device, automatic provision of a shot clock, and the like.

An elongated playing surface includes: a long axis, a rigid planar cue section at one end, at an opposite end a rigid planar object section rotatable about the long axis, and a mid section twistable about the long axis interconnecting the cue and object sections. The game is played with a cue ball, object balls and cue stick. End and side rails confine the balls atop the playing surface. One end rail, affixed to the object section, defines one or more openings at which are disposed respective ball pockets. The object of the game is to drive the object balls into a pocket by striking them with the cue ball driven by the cue stick. From time to time a mechanism tilts the object section and twists the mid section laterally about the long axis causing balls on said sections to roll according to gravity, making them moving targets.

Disclosed are systems and methods of calculating projected impact generated by sports and gaming implements. An exemplary method comprises: receiving a measurement from a sensor associated with a subject of impact; receiving a measurement from a sensor associated with an object of impact; wherein the at least one received measurement includes one or more characteristics of movement of the subject in response to an external stimuli and one or more characteristics of movement of the object in response to the impact by the subject; calculating, by a projection tool, a projected impact of the subject on the object before the actual impact; and calculating, by a modeling tool, a model of movement of the object in response to the impact by the subject based at least on the projected impact and one or more rules defining a movement of the object based on the projected impact by the subject.
