After launching Tsuri-Sta, the world's first mobile social game, in 2007 and later Driland, GREE went on to develop a rich portfolio of original games. Today, GREE provides games to people around the world via the App Store and Google Play from its studios in Japan, North America, and South Korea. GREE has also continued to enhance the browser-based game content available on GREE Platform, which it opened to developers in Japan in 2010. In April 2014, GREE launched a new Japan-based studio named Wright Flyer Studios dedicated to producing original mobile games for iOS and Android.
