The Japanese Persona 4: Arena website launched a new mini-game where you shuffle cards to gain points. With enough points you can download official Persona 4: Arena wallpaper images for each of the the characters. Everyone loves trying their luck but the problem is you only get three chances per day! As you can imagine it could take a while to unlock all of the wallpapers.
Luckily for us, the fine community over at Siliconera somehow acquired all of the wallpapers so you can skip the game and download them now! Hit the link above to pick yours.
