If you play your cards right, you could be one of the ones selected.
The closed beta for Blizzard's Hearthstone: Heroes of Warcraft has begun for the Americas region, and the company is going to be inviting a select group of people to test the upcoming trading card game.
To be eligible, make sure you have a Battle.net account and click the box saying you are interested in the Hearthstone beta. It's that easy. Of course, I still have yet to get my invite. I'm sure its coming. At least I think it is. They better let me in.
Blizzard has not announced how long the beta will last, but there is no NDA associated with it, so if you get in, be sure to send us your screenshots and share you experiences in the comments below.
Don't get too attached to any cards that you get during the beta, however, as Blizzard plans to wipe all accounts when free-to-play Hearthstone officially goes live some time later this year.
