Abstract: A system for in-stadium mobile games includes a server computer for collecting and distributing sporting-event data; and a client computer in communication with the server computer over a network. The client computer includes a computer memory for storing software instructions; and a computer processor for executing the software instructions. The software instructions perform the steps of (1) receiving, from a user via an input device, a selection of a plurality of athletes competing in a sporting event; (2) receiving, from the server computer, information regarding performance of the selection of the plurality of athletes; (3) during or upon completion of the sporting event, computing a score of the user based on the selection and the performance; and (4) indicating that the score of the user surpasses at least one other score of another user and that the user be awarded a prize.
