Abstract: A method and system for providing games of chance based on partial entries are disclosed. The method comprises exchanging partial entries in a non-intrusive manner amongst participants, and combining partial entries to make complete entries to enter into draws for prizes. A drawing server may implement a variety of reward schemes, and prize certificates or notifications may then be communicated electronically. The disclosed method and system may also be used for product or brand promotions. Prizes certificates may be redeemed online or at a point of sale equipped with a validation terminal in communication with the drawing server.
