Abstract: Various embodiments of alerts on mobile devices are described. In some embodiments, one or more gaming preferences registered for a mobile device may be read. A set of games that are not implicated by any of the gaming preferences registered for the mobile device, but that have high rates of coincidence of alert registration relative to other sets of games associated in a register with the plurality of other devices, may be identified. In some embodiments, an estimate of a correlation among user interests in a subset of a plurality of games may be determined based on the number of devices registered to receive alerts for the games in the subset. One or more games of interest for which the first device is not registered to receive alerts may be identified for a first user based on the estimate. Other embodiments are described.
