A 'best player vote' is an entertaining and engaging feature that fans appreciate. The player voting can easily be used together with lottery-functions, such as the Push Lottery. An example of such a lottery is that among all registered voters, one is randomly chosen and awarded a prize. This feature is one that business partners could be interested in and willing to pay for. Furthermore, the voting could be branded for the business partner, and the voting icons could change to the partner's logo when a user taps on them.
The voting situation can be shown on the big screen during the game e.g. by exporting jpeg pictures from the client console. Your business partner now has a branded player voting, with engaging features and gets visibility on the big screen? Sounds like a feature that with little effort can transform your app-costs to revenue.
