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 per day. However, there is no limit on the number of cards you can receive.
If you're missing any cards, tap the "Request Cards" tab and ask your friends for help. You can also send a "request" link to any other player via a messaging app or the Official Facebook Trade groups:
Papaya Solitaire Cash: Card Trading Official Group
Papaya Bingo Cash: Card Trading Official Group
Bubble Cash: Card Trading Official Group
Golden cards cannot be traded.
