• All packs random and it’s the contents are unpredictable.
• Gain cards by getting them as rewards by competing or even from certain quests. Cards can also be purchased in the shop by using gold or even by real money.
• Each card in a pack can get a chance to become a golden version of the card, which is higher in quality.

Reviews

Between its friendly design and its flexible approach to a free-to-play economy, Hearthstone has successfully pulled me into a genre that I didn’t care about in the least. But even more incredibly, it’s kept me rapt longer than any games I’ve played in years, and shows no signs of letting up.

Hearthstone is a wonderful game. Nostalgic, simple and best of all: fun. This is the best online collectible card game you can play. Just be careful how much you spend in it.
