I started playing the game recently, so here’s some info on what it’s like!
For those who don’t know about the game, it’s a social network game by Gree and Taito, and is playable on the iOS and Android platforms. It’s web-based, and you don’t have to download an app in order to play it. The game’s website is here.
This is also the game where the Fairy Tail cards you see being posted on Tumblr come from.
This is how the main page looks like:
It shows the guild you belong to, the guild’s level, your basic stats and some links to other pages. The main image changes depending on the cards that are currently in your deck.
