Abstract: A playing device system can be used by a number of players with various playing devices at a distance from each other. Each of these devices can be connected to a common host computer via a remote data transmission system and they are controlled by a random symbol generator which determines a winning combination of symbols. In order to simplify the system, the symbol generator is assigned to the host computer, with the playing devices constituting a display indicating the winning combination of symbols generated by the random symbol generator and connected with an input device to participate in the continuous determination of the winnings.

Abstract: A method and system for assuring the smooth, rapid execution and automatic control of a tournament. Participants' names are announced, and the participants notified to take their turn in the tournament by means of one or more electronic displays accessible to a number of potential participants. Personal identity data corresponding to the participants are entered, up to a given number of participants, based on the particular tournament variant via a data reading unit linked to each display. The groups of participants are arranged in order using a random access technique. Upon completion of each match, the winner is announced, and the groups of participants are organized for succeeding rounds. The tournament continues until completion, when the results are analyzed by the system and displayed.

Abstract: A system for automated running of sports contests including a computer unit, a machine-readable data carrier for each such contestant, a data carrier containing control data for each type of contest to be performed, and at least one reader for the data carrier. Contestant data and control data are exclusively input into the computer unit using the data carriers. At least one display device linked to the computer unit displays contest data. The individual phases of the contest running may be determined by the sequence of the data carriers introduced in the reader(s).
