I believe it's coming out on iTunes right before Christmas, then eventually on Android and Google Play. They said it's pay to play, I guess that means free to play but you must pay for additional features.
Looks promising. I can see myself playing this everyday. It looks like the online Winx Game that ysed to be on winxclub.com
I think it's safe to officially say that Believix is the Trademark or mascot of the transformations. That transformation was 2 Seasons ago and it is still relevant, seeing as in this game you will train to become a Believix Fairy.
