For as popular and successful as Nintendo's amiibo figurines have been in both the fan and collector markets, it seems that few people who own the toys know the extent to which they can link them to all kinds of video games for the Wii U and 3DS.  Yes, the Super Smash Bros. link is well known, but did you know that the amiibo can unlock extra functions in games such as Chibi Robo: Zip Lash, Captain Toad: Treasure Tracker, and Kirby and the Rainbow Curse?  Nintendo's messaging needs work, but fortunately the Internet is here to help.  A Twitter user going by the name MoldyClay has put together a massive compatibility chart to spell out which amiibo which work which games and what functions are unlocked when linked together.  From Code Name: S.T.E.A.M. to Mario Kart 8, this chart has it all in one easy-to-read place.  As of this writing, it's up to version 9.0.

As an amiibo owner (I own a dozen of the figurines ranging from commoners like Smash Mario to the hard-to-find Ness), I appreciate this chart to keep track of what I can do with the games I own.  I enjoy amiibo functionality.  That said, what I do not enjoy is that amiibo for characters can split into multiple product lines and one version of a character may not unlock the bonus that another version does.  For example, I own the Smash Bros. Kirby amiibo.  I can use this Kirby in Kirby: Planet Robobot for the 3DS to unlock a hard-to-find Smash power-up for Kirby.  However, only the recently released Kirby amiibo from the new Kirby line of figurines unlocks the exclusive UFO power-up.  I know Nintendo wants to sell me as many amiibo has humanly possible, but buying two Kirbys just doesn't sit right with me.  Kirby should be Kirby regardless of his shape (especially as older amiibo go out of production; it's been a while since I've seen a Smash series Kirby on a store shelf).
