My Nintendo

My Nintendo is a reward program that acts the successor to Club Nintendo, that launched in 2016. It incorporates all services

Missions & Coins
There are two types of rewards. The Gold Coins are basically the revised version of the Wii U's Digital Deluxe Program though for all purchases on the eShop. Purchasing games or DLC on the eShop will reward the buyer with an amount of Gold Coins depending on how much the game cost.

Platinum Coins are obtained from doing certain tasks in Nintendo's ecosystem like linking social network accounts to the Nintendo Account or signing in regularly.
