Computer network implemented casino marketing system

摘要

A method inviting members of the public to participate in various free, computer network implemented gaming events awards prizes to those participants that have obtained some predetermined ranking in the event. The method divides eligibility criteria in each gaming even in accordance with a plurality of intersecting and non-intersecting subsets of demographically significant indicia. The process of collecting the prize includes comparison of the recipient's personal data against the particular subset, thus insuring a highly reliable data base in each of the subsets. In this manner accurate data is collected that may be useful in marketing endeavors.
