Heyzap, the social discovery platform for mobile and online games, has been hard at work adding pieces to its mobile experience. The startup recently brought check-ins to its mobile platform, allowing users to check-in to their favorite games to share scores and achievements on Facebook and Twitter. This also included, a la Foursquare, a badge rewards system, in which gamers can become the “boss” of a game by checking in with gusto. And, like Foursquare, Heyzap has been collecting data on those check-ins, and is today offering free, personalized game recommendations and locations on game check-ins for Android. (The iOS update will be available at the end of the week.) This update continues to add functionality to Heyzap as a mobile platform: With the ridiculous amount of games out there in the mobile market, game discovery – especially personalized discovery – is essential.
