Information kiosks for Nintendo's upcoming line of NFC-powered toys, called amiibo, have started popping up at retail locations like Walmart, offering some new details on which toys will be compatible with which Wii U games. As it stands right now, the Yoshi amiibo is your best toy-to-game compatibility value.
Nintendo's interactive amiibo kiosks show that games like the already-released Mario Kart 8 will support Mario, Peach, Yoshi and Donkey Kong, while Mario Party 10 is confirmed to support Mario, Peach and Yoshi. Nintendo recently announced amiibo support for Hyrule Warriors, meaning Link will be compatible with at least two games. It appears that Yoshi is currently the sole amiibo currently supported in his 2015 game, Yoshi's Woolly World.
Of course, all this is subject to change, as Nintendo is adding amiibo support to already released titles through software updates. It's conceivable to Mario Kart 8 could eventually support a wider range of amiibo figures, like Link and Animal Crossing's Villager, when they join the kart racing game. The same could be true for characters like Luigi, who is only officially supported by Super Smash Bros. for Wii U, but also appears in Mario Kart 8 and Mario Party 10.
Nintendo's amiibo kiosks (and the toys' website) hint that there are some more unannounced figures on the way. Silhouettes and art for Nintendo's Bowser, Tom Nook, Pikmin and Toad are shown, even though figures for those characters haven't been announced. Nintendo has confirmed amiibo support for upcoming Wii U game Captain Toad: Treasure Tracker, but hasn't confirmed which figure will work with the puzzle platformer.
Here's a quick look at which games are said to work with which amiibo figures. (Sorry, but the Captain Toad amiibo is still unconfirmed.) Support for amiibo will also come to Nintendo 3DS games.
