GungHo Online Entertainment Inc. plans to strike partnerships with third-party game developers and share its recipe for success as the maker of the world's highest-grossing smartphone title begins to expand into publishing.

President Kazuki Morishita said the company has hit on the right formula to win over notoriously fickle gamers and is eager to share it.

"Companies have been coming to us for years begging to publish their games. We are now getting ready to do that," Morishita said Wednesday in an interview in Tokyo. "It's just not something you can teach. It's an accumulation of many years of practice, a kind of a secret sauce that has been infused into the pot."
