We pre-install our mobile games and game platforms on handsets that we design, which enhances our knowledge of user habits and preferences and allows us to quickly adapt to industry trends.

We have amassed a portfolio of over 450 mobile games as of March 31, 2012, of which 150 are self-developed and 300 were licensed from third-party developers. All of our feature phone games are self-developed, many of which are among the most popular, as measured by downloads, and highest grossing, as measured by revenues.
