• You can collect cards by opening card packs that you gather from Events, Factory Pass, Hard/Super Hard/Ultra Hard Levels, or receiving them from a friend.
  • All cards have a different number of ducks. The ducks indicate the rarity of the cards.
  • There are two types of cards: Common Cards and Gold Cards. Gold Cards cannot be sent to a friend.
  • The cards you earn from opening packs can either be copies of the ones you already have or new cards. Copy cards contribute to opening Duck Chests, while new cards are added to your progress. 
  • You can track your progress with the cards you have earned on the Collection tab.
