Abstract

A process is provided for generating a plurality of gaming card arrays, each formed of a plurality of symbols positioned in predetermined symbol display locations, in a plurality of remote devices connected to a main station. The process includes the steps of developing a plurality of seeds to be utilized as input for generating gaming card arrays, and generating, at each remote device, gaming card arrays in accordance with input received from the main station, utilizing a pseudo-random number generator seeded by at least a portion of the plurality of seeds. In one preferred form, a pre-processor is utilized to screen potential seeds and save only those capable of creating unique gaming card arrays in a seed list. The seed list is then accessed when needed and seeds, together with other operational data, are transferred to the remote devices whereat the gaming card arrays are created and stored for use. In another embodiment, a pre-processor generates a plurality of secondary seeds from a predetermined list of primary seeds, screens the secondary seeds to determine which will produce unique gaming card arrays, and stores those which will not create unique arrays in a duplicate secondary seed list. The duplicate secondary seed list is then accessed, when needed, in order to eliminate the possibility of creating duplicate arrays within a remote device. A system for processing win patterns is also provided.
