Players can then buy packs of new cards through gold or microtransactions to customize and improve their decks.
Winning matches and completing quests earn in-game gold, rewards in the form of new cards, and other in-game prizes. Players use their limited mana crystals to play abilities or summon minions to attack the opponent, with the goal of destroying the opponent's hero. The game is a turn-based card game between two opponents, using constructed decks of 30 cards along with a selected hero with a unique power. The game features cross-platform play, allowing players on any supported device to compete with one another, restricted only by geographical region account limits. It was first released for Microsoft Windows and macOS in March 2014, with ports for iOS and Android releasing later that year.
