Players customize their decks with any gained cards to improve their chances of winning and gaining further rewards. Hearthstone is purposely designed to exclude card trading, while allowing players to disenchant unwanted cards into a quantity of arcane dust that can then be used to craft new cards of the player's choice. Players start the game with a limited collection of basic cards but can gain rarer and more powerful cards through purchasing packs of cards or as rewards from specific game modes. Players can choose from a number of game modes, with each offering a slightly different experience. Hearthstone is a digital-only collectible card game that revolves around turn-based matches between two opponents using pre-made decks of cards. 2.1 Basic, Classic, Reward, and Hall of Fame.
