Abstract: The random number generating capability of a computer is used as a basis for producing sets of alphanumeric configurations for a plurality of bingo cards, and the comparator capability of the computer is utilized to eliminate duplication from among the plurality. A computer-controlled, high-speed graphics printer is used to print, on sheets of paper, bingo cards from among the plurality.

Abstract: A computer uses a random number generator as the basis for formatting the number combinations of new bingo cards, and stores each new combination in memory. This proceeds until the number of generated and stored cards reaches a designated number, whereupon the computer scans the combinations in memory to detect duplicates, and removes combinations in such a way as to eliminate duplication. A high-spoeed, graphics printer, for example a laser printer, is then used and computer-controlled to print bingo cards on paper, using the number combinations in memory.
