Nintendo just announced that Super Mario Run will launch for iOS devices, including the iPad and iPhone, beginning on December 15 in 151 countries. It said some content will be available for free but that users can unlock the full game by paying a one-time fee of $9.99

“The wait is almost over for a Super Mario game that can be played on mobile devices,” Doug Bowser, Nintendo of America’s Senior Vice President of Sales and Marketing, said. “Developed under the direction of Mario creator Shigeru Miyamoto, Super Mario Run brings a new take on the series’ beloved action-platforming gameplay to iPhone and iPad for the first time.”

Super Mario Run may be an early success

Super Mario Run was first announced during Apple’s iPhone 7 event in September. Nintendo has since confirmed that it will also launch on Android smartphones, though we don’t currently know exactly when. It looks like it’s going to be an early success, too, with more than 20 million potential gamers signed up for notifications about when the game will launch.
