A light guide plate according to one or more embodiment is formed of a panel transparent to visible light, and includes: a plurality of first prisms arranged along one surface of the light guide plate and distributed in a first pattern to reflect the visible light emitted from a first light source and entering the light guide from an input surface toward another surface of the light guide plate; and a plurality of second prisms arranged in a second pattern to reflect the visible light emitted from a second light source and entering the light guide from the input surface toward said other surface of the light guide plate. Each first prism includes a reflection surface directly facing the first light source, and each second prism includes a reflection surface directly facing the second light source.

A game system may comprise a board comprising a plurality of pegs extending from the board, wherein the pegs may be disposed in rows; at least one deflector configured to be coupled to at least two pegs aligned with one another; at least one ball configured to move on the board between and/or along the pegs and deflector(s) from a start end to a goal end of the board; at least one goal configured to be coupled to at least two pegs in a goal row of the rows of pegs, wherein the goal is configured to receive a ball; and a plurality of play selectors which determine a play for each player during a turn of a game. The goal of the game may be to get a ball into a goal by navigating across the board having the pegs and deflectors as obstacles to movement of the ball.

A minimum display unit forming a pattern, displayable by a light guide plate of a display device, has first and second prisms with reflective surfaces in a curved surface shape that is convex relative to an incident surface of the light guide plate. The first and second prisms are configured such that a ratio of light quantities from first and second light sources having different emission colors into the light guide plate, reflected by the reflective surface of the first prism, and directed to a predetermined direction is a first ratio; a ratio of light quantities from second and third light sources having different emission colors into the light guide plate, reflected by the reflective surface of the second prism, and directed to the predetermined direction is a second ratio. The first and second ratios are set such that the minimum display unit is displayed in a predetermined display color.

A ticket redemption game having an upright cabinet. The upright cabinet houses a cylindrical drum which may be rotated through the use of a control by at least one electric motor. In the interior of the cylindrical drum are a plurality of balls. When the drum is rotated, the plurality of balls is moved from a low point to an apex of the cylindrical drum along an interior circumference of the cylindrical drum by the aid of traction elements.

The present invention is directed at enhancing pinball gameplay through non-synchronous multiplayer competitive and cooperative play. In the primary embodiment this is achieved by treating the logic and circuitry of an individual pinball machine as a Client, that is connected to a server or Host. The Host is in bidirectional communication with the individual pinball machines or Clients. The status of the Client, such as score, progress on completing features and other game metrics may be communicated to the Host at predetermined intervals. These game metrics may be communicated by the Host to all Clients. When a gameplay objective is completed on a client, the player is presented with a gameplay choice. This choice may be to change the status of his Client or change the status of another player's Client.

A target assembly includes a target post mounted to an underside of a playfield and sized to extend through an opening in the playfield. A centering device is mounted to the target post between a first end of the target post and a second end of the target post and a centering plate secures the target post to the underside of the playfield, wherein the centerplate and the centering device form a fulcrum for the target post to pivot as a lever. Impact of a ball with any portion of the target post, and in any direction, above the playfield causes the target post to pivot about the fulcrum, where a sensing switch senses the target post movement. A biasing element coupled to the centering device biases the target post into a rest position and returns the impacted target lever towards the rest position after impact by the ball.

A display device of an amusement game is caused to present in a main screen information associated with a first one of a plurality of active game play modes of the amusement game and to present in a secondary screen information associated with a second one of the plurality of active game play modes of the amusement game. A plurality of lighted features and at least one sound generating device are controlled using instructions that are associated only with the first one of the plurality of active game play modes while input received by a plurality of game play devices, resulting from an interaction between the plurality of game play features and an object that is moving relative to a playfield of the amusement game, is used to affect play of and/or scoring of play of the amusement game using instructions that are associated with each of the plurality of active game play modes.

A display device includes: a first display unit which is a transmissive display unit; a transparent backlight formed of transparent material, provided relative to the first display unit opposite the viewing surface of the first display unit, and configured to emit light toward the first display unit; a light source configured to output object light to the transparent backlight where light from an object provided opposite the light emission plane of the transparent backlight is output toward the transparent backlight and the first display unit; and a controller configured to control the first display unit, the transparent backlight, and the light source so that light emitted from the transparent backlight shows an image on the first display unit, and so that the object light can pass through the transparent backlight and the first display unit and be output.
