Hearthstone is bringing some big changes to its Arena mode

Blizzard announced some big changes coming to the Arena mode of its hit digital card game, Hearthstone.

The PC mobile card game’s Arena mode has players creating their own decks by picking cards from selections of threes. Playing Arena costs $2 or 150 in-game gold. You get rewards based on how well you do, and you keep playing until you either rack up three losses or 12 wins. The mode gives Blizzard a way to earn money off its free-to-play game outside of selling card packs.
