My Nintendo

From the main screen in Super Mario Run, you'll see My Nintendo in the upper right corner. If you have (or create) a My Nintendo account, you can link it to Super Mario Run and use your Mii as your icon. This will also allow your Super Mario Run data to be stored on Nintendo's servers so that if you accidentally delete the game from your phone, your progress won't be lost. Last, but not least, you receive special missions that when completed give you Points, which can be exchanged for extra gold coins, Rally tickets, items, and the character Toad.
