What is the “trade” feature, and how can it help me?
You can trade cards with your friends and other players to help each other complete an album and win the grand prize.
Use the Card Trade Center to send duplicate cards you have and to collect all the cards other players send you. You can ask for any card they are willing to spare or even specific cards you need to finish a set.
Remember that you can only send a limited number of cards a day. But there is no limit on how many cards you can receive.
If you're missing any cards, tap the "Request Cards" tab and ask your Facebook friends for help. You can also send a "request" link to any other player via a messaging app or the Card Trading Official Group on Facebook.
Golden cards cannot be traded.
