Abstract: An on-line method and apparatus for collecting demographic information from a user of a home WWW site and for dynamically selecting questions to present to the user is disclosed. A plurality of sponsor symbols are displayed for the user on the home WWW site. A signal is received at the home WWW site from the user indicating a selection of one of the sponsor symbols by the user. In response to the selected sponsor symbol, a first set of one or more prize symbols are displayed for the user on the home WWW site. A further signal is then received at the home WWW site from the user indicating a selection of a prize symbol from the first set of prize symbols by the user. Next, the system determines whether the user is a registered user of the home WWW site and, if the user is not a registered user of the home WWW site, the system collects demographic information about the user during registration of the user on the home WWW site.
