Throughout the season, you can assemble a collection of cards that drop out of card packs as a reward for various activities in the game.
Each completed album will grant you a nice reward, but true collectors are after the super prize. Complete a collection and hit the jackpot: loads of chips, cash, gems, and a unique skin.
You've completed the collection, but you still get card packs? Don't stop! You can now continue opening card packs and acquiring gems, but make sure you exchange them for chests before the season ends!
