Abstract: A system and method of enhancing shopping search engines and games of chance by permitting the user to search for and locate the prize the user seeks to win or buy, and then playing a game of chance to win the specified item, or going to the web site to buy. The system calculates a dynamic probability of winning the item based on several factors. The system randomly generates a trial outcome of an event trial and an outcome indicator, with the probability of the event trial generating a winning trial outcome corresponding to the calculated probability of winning. The outcome indicator represents either a winning trial outcome or a losing trial outcome. In response to a winning trial outcome, the system purchases the item for the user from the independent third-party retail vendor at no cost to the user.

Abstract: A computer-implemented method including receiving a search request for a product; processing the search request with a processing device; generating a message containing information regarding at least one product offered by a retail vendor; transmitting the message; automatically providing the user with an option to play a game to win a selected product from the product information without the user first making any payment or requesting the option; electronically calculating a dynamic probability of winning the selected product by the user based on one or more factors; electronically and randomly generating a trial outcome for a game of chance; generating an outcome indicator; displaying the outcome indicator to the user; and in response to a winning trial outcome, purchasing the selected product for the user from the independent third-party retail vendor at no cost to the user.

Abstract: In one aspect, the system of the present invention enhances shopping search engines and games of chance by permitting the user to search for and locate the prize the user seeks to win or buy, and then playing a game of chance to win the specified item, or going to the web site to buy. In another aspect, the system of the present invention adjusts the probability of a user's winning a game of chance in accordance with the revenue that the system has received from the user.
