What is the Prize Board?
The Prize Board is a section where you can place cards from your collection to win prizes every certain period of time. To access it, you'll have to select the game's Shop and tap on the gem icon on the bar at the top of the screen.
There, you will have the possibility to place up to three cards to receive free prizes. If you have not placed any cards, you will see three blank spaces and, by tapping on any of them, you will be redirected to your Album to choose the cards you want.
