Abstract: An interactive reward system to allow a user to collect and redeem rewards is disclosed. The system can operate over the Internet or any other network of linked mirco-processors which can reference a database. The user can obtain rewards when using a user computer. A reward can be obtained when the user selects an image or text, such as an advertisement, that has an associated (optional) reward indicator. A reward indicator can be, for example, a special logo or icon. When an image with a reward indicator is selected by the user, control is passed to a central computer that identifies the user and adds the reward to a database storing a list of rewards available for redemption by that user. Each reward is associated with a promoter's offer. Typically, each promoter will have a computer, such as a webserver. After a reward has been allocated to the user, the central computer passes control to the promoter's computer associated with the selected image.
