Collect all 27 spooky Halloween cards and unlock special rewards

The Halloween card collection event is here! Win levels to earn ghosts, spend them to open card packs and fill your spooky album. Each pack reveals a card of different rarity, and every 6th pack guarantees a card you don't have yet. Duplicates turn into coins, and progress milestones give extra rewards. You can also open free packs by watching ads. Complete the whole collection before the event ends!
