Learn how to score some easy My Nintendo Platinum Coins.
My Nintendo has added three new Missions, and one secret one, for E3 this week. All of these require My Nintendo members to find and click on hidden things on Nintendo's E3 site. This guide will show you how to obtain these secret coins. However, you better hurry because these missions expire on June 17 at 11 a.m. PT.
