A game button includes an enclosure in which are mounted at least one variable display, a sensor, a memory, and any other components of the game button. The variable display is capable of presenting a plurality of images thereon. The memory is communicatively coupled with the variable display, is adapted to store information for producing the plurality of images presented on the display, and is physically located between the variable display and the sensor.

The present invention is a gaming machine having a player time-selectable bonus award scheme whereby the player may redeem, at a time of the player's choosing winning outcomes accrued during base game play. Redemption of each of the accrued winning outcomes is accomplished when a player selects an option to display a winning symbol combination associated with the winning outcome. Selection of the option to display the winning symbol combination associated with the winning outcome always yields an award and sometimes yields another winning outcome, again redeemable at a time of the player's choosing. A counter display on an intelligent button of the gaming machine increments a number as each winning outcome is accrued, and decrements the number as each winning outcome is redeemed. Thus, a second game may be initiated before a first game is complete.

A ball locking device includes a plurality of posts arranged to retract into or extendabove apertures in the game playfield. In the extended position, the posts form a cage which confines a game ball therein. The posts are arranged, for example, in a circular pattern and spaced from one another at a distance less than the diameter of the game ball. A solenoid, in conjunction with sensing devices, controls the movement of the posts to capture the ball in play or to release the captured ball at an appropriate time during game play. The locking device is hidden from the players view when in its retracted position.

A pinball game comprises a cabinet, an inclined playfield, and a video display. The inclined playfield supports a rolling ball and a plurality of play features thereon. The cabinet includes a pair of opposing side walls and a rear wall extending between the opposing side walls. The playfield is housed within the cabinet such that the playfield is partially encompassed by the side walls and rear wall of the cabinet. An upper portion of the rear cabinet wall extends above a level of a rear portion of the playfield. The video display is mounted to this upper portion of the rear cabinet wall and is located in close proximity to the rear portion of the playfield. By mounting the display to the rear cabinet wall in close proximity to the playfield, the display can be easily viewed by a player during game play and, yet, allows the playfield to be easily serviced for maintenance and troubleshooting purposes without interference from the display. For maximum clarity of images shown on the display, the angle between a front surface of the display and an upper surface of the playfield is preferably such that the front surface of the display is generally perpendicular to a sight line extending between the display and a typical player.

An illuminable ramp assembly for a pinball game having a playfield supporting a rolling ball thereon comprises an elongated molded plastic housing and a ball ramp extending alongside the housing. The housing encloses a power supply, a gas tube, protective end caps, and cushioning supports. The gas tube is powered by the power supply. To effectively suspend the gas tube within the housing and, at the same time, provide the gas tube with shock resistance, the protective end caps are mounted over opposing ends of the gas tube, and the cushioning supports are intermittently located along the length of the gas tube. The cushioning supports partially encompass the gas tube and are interposed between the gas tube and the housing. The ball ramp includes an entry end and an exit end. A switch capable of detecting the presence of the rolling ball is preferably located near the entry end of the ball ramp. In response to the rolling ball being delivered to the ball ramp via its entry end such that the rolling ball actuates the switch, a game controller causes the power supply to illuminate the gas tube with an illumination pattern.

A display panel for a pinball machine utilizes a lightweight plastic housing member with a plurality of apertures therein for retaining light bulbs. A glass lens and film having an image thereon are resiliently retained on the housing member with channel members that extend about the periphery of the lens and housing. The display may be removed and installed as a unitary piece in a pinball game cabinet.

The play feature of the invention comprises a planar surface which is rotatable above the playfield of a pinball game between a ball receiving and a ball discharge position. An electromagnet is attached to the planar surface. A ball detector, such as an eddy current sensor, is mounted to the playfield adjacent the housing to detect the approach of a pinball to the electromagnet. The magnet can be energized to suspend a ball from the planar surface which is then rotated to a ball discharge position where the magnet is deenergized to discharge the ball.

A pinball momentum transfer device or Newton ball device utilizes an impact bail anchored to the playfield. The impact ball, in cooperation with guide elements on the playfield, defines a ball travel area for captive balls to which momentum can be transferred from a game ball via the impact ball so as to project one of the captive balls towards a target element contained within the ball travel area.

The play feature of the invention consists of an inclined ramp mounted for tilting motion along a single axis. A reversible electric motor, controlled by the flipper buttons, can pivot the ramp in either direction about the axis. The player, by manipulating the flipper buttons, controls the tilting of the ramp thereby to control the path of travel taken by the ball as it rolls down the ramp. The ramp is provided with a plurality of bumpers, roll over switches and out holes that allow the player to score points if the player traverses the ramp in the manner directed by the game program.

The play feature of the invention consists of a rotary wheel having a plurality of ball receiving sockets located therein. The wheel is rotated such that an empty socket is disposed in a ball receiving position. During the course of play, the game player can direct a ball into the socket where it is retained. The wheel is then rotated to expose another empty socket into which a player can direct a second ball. Once all of the sockets are filled with balls, the game's microprocessor will rotate the wheel to return the balls to the playfield for multiple ball play. The wheel is rotated by an electric motor that is controlled by optical sensors.

The playfield is supported on a moving pivot that allows the playfield to move linearly away from the back box as it rotates away from the cabinet such that the playfield can pivot through an angle greater than 90.degree.. The moving pivot includes a pivot pin fixed to the wall of the cabinet which slidably engages a rail fixed to the underside of the playfield. The rail terminates in a locking mechanism that engages the pivot pin when the playfield is moved linearly to thereby fix the playfield to the pivot pin such that the playfield is capable only of pivoting motion.
