There are many things I expect to happen that within time come about, one of these is Pokemon Shuffle seeing release on mobile devices. The Free to play 3DS game never really felt like an experience for a dedicated gaming platform so it seemed inevitable that the game would make the movement to such a device as Mobile.
As the game passed 4.5 million downloads, The Pokemon Company today announced that Pokemon Shuffle would be making its way to mobile devices.
As of yet no official release date has been announced for when the game is going mobile, apart from a general later this year. Based on the trailer the game seems to be the exact some game people played on the 3DS just with optimization for IOS and Android, in other words if you already have it for the 3DS don't bother with a mobile version. You can watch the trailer for the game below:
