Abstract: An actuating device for a game machine is disclosed in which the hand or fingers do not fatigue on prolonged use, thereby imparting an optimum feel for the user. The actuating device has a main body unit and first and second grips projecting from one side of the main body unit at opposite ends thereof. Vibration-imparting units are enclosed within the first and second grips. First and second actuating units are mounted at opposite ends of the main body unit. The first and second actuating units include plural thrusting actuators which protrude from the upper surface of the main body unit. Third and fourth actuating units are arranged on the proximal ends of the first and second grips so as to confront one another. The third and fourth actuating units include rotation actuators and signal input elements actuated by the rotation actuators.

Abstract: A computer network which manages multiple simultaneous bingo games having a potentially large number of bingo cards. The computers simultaneously and in parallel compare called bingo numbers to bingo cards stored in each respective computer (and also double-verfy winning cards). Called numbers may be applicable to one, many, or all of the simultaneous bingo games, and the games may have different times or different rules. Bingo cards are distributed in the network in accordance with number of hits needed by the cards: “one-away” computers handle bingo cards needing one more hit; “two-away” computers handle cards needing two hits. The computers in the network also generate statistics on the progress of bingo cards toward wining patterns. These reports can be collated to develop overall statistics for any game in progress; in addition, the computer system broadcasts personal information, or live audio or video, of winning or close-to-winning players.

Abstract: A pinball machine has been designed with several novel mechanical and electrical features such that it is easily retrofittable or convertible between a first pinball game and a second pinball game. The pinball machine includes a cabinet, a playfield, a panel, an electronics system, and a video display. The playfield is mounted in the cabinet with the panel mounted to the cabinet and overlaying at least a portion of the playfield. The video display is mounted generally above the cabinet and is disposed to project video images onto the panel for viewing by the player. The electronics system includes a control unit and a plurality of input/output elements which are mounted to the playfield. The control unit, which includes a controller and memory for storing game instructions and video images, is coupled to the plurality of input/output elements. The controller executes the game instructions to cause the video images to be displayed upon the video display.

Abstract: A system for controlling the operation of electronically linked gaming machines which enables information to be transferred between machines and from each machine to a control unit. In particular, credits on a machine can be transferred to another machine and the credit state of each machine can be interrogated and adjusted from the central control unit.
