Amiibo Tap: Nintendo’s Greatest Bits will allow players to tap their amiibo to the GamePad and play 3 minutes of a retro Nintendo game based on that amiibo. For instance, tapping your Mario amiibo will pull up a demo of Super Mario Bros. for the NES. It’s a similar experience to what Nintendo included with Super Smash Bros. for the Wii U. The game will be a free download available this “Spring”.
