Blizzard's free to play online card game, Hearthstone: Heroes of Warcraft, is now available to play for everyone and is out of the beta stage. The open beta didn't seem to last long, as it started around January of this year.
Hearthstone will have about 300 different cards to start with and booster packs of 5 will cost $1. Like card games of norm, the more you spend the better chances you have of winning.
Those wanting to play on an iPad or an Android device will have to wait a bit. Those clients are still being worked on, but PC and Mac users can get started now by downloading from the website.
