There are three kinds of chests that you can purchase; the more expensive the chest, the more Cards you’ll find within. The quality of the Cards you can get from a chest is dependent on your current Village Level. One you reach the higher Village levels, you also have the chance of getting special Gold Cards from the chests you open. Gold Cards are simply rarer versions of other cards, and their Collections offer much bigger rewards upon completion.
One of the most exciting mechanics in Coin Master is the Card Trading system. You can send up to 5 Cards to your friends every day, so it’s a good idea to join Coin Master forums and communities. Many have dedicated Card Trading sections where you can strike trading deals with other Coin Master players.
