If you have an account on fifa.com you can play this easily(if you don't have an account, create one, it's easy). You can swap the duplicates, you can enter promo codes, you can find some stickers on the website(like the stadiums), you get a pack or more with stickers everyday etc. Most importantly, you can adhere to a group. I've created one for the ones here interested.
Anyway, here's a link to the game: http://www.fifa.com/stickers/index.html and for our group: name - FCBes ; password - spainftw
