You have to feed, play with, and clean up after both, but the differences end there. The ON has you exploring Tamagotchi Planet and breeding to create a one-of-a-kind Tamagotchi. You also get to raise/breed pets for your Tamagotchi. There's Bluetooth and app integration, though the app is shutting down in August of this year.
The Pix is much closer to a classic release, where the focus is on spending time with the Tamagotchi you're raising. The camera allows "cooking" (free food!) and customization of items that your Tamagotchi can play with or use to decorate their room.
Both versions have a variety of mini-games to play and are in full color, so you'll have plenty of fun with either model.
I have a quiz that can help you figure out which one suits you best. Maybe it will help you decide?
The digital pet world is blessed with bounty this holiday season, as there are FOUR mainline Tamagotchi models on the market! Find out if the Original, On, Pix, or Smart best matches your play style. FANMADE, NOT ENDORSED IN ANY WAY BY BANDAI.
