Hearthstone is an upcoming free-to-play digital strategy CCG. It was announced March 22, 2013. While set in the Warcraft universe, players assume the role of a hero from Warcraft's storied history and amase a card deck to defeat other players. Hearthstone employs a different type of development team than is normally used by Blizzard. Team 5 (as they have been dubbed) is only made up of 15 developers that are "scrappy and versatile", will experiment more, and have faster development cycles. The game will also differ from other Blizzard Projects as it is their first official game to be playable on a tablet. The game is currently in beta and appears to be met very positively.
The beta is set to launch sometime in the summer of 2013. It is scheduled to launch in the U.S. and Blizzard hopes to launch a beta test in other region after the initial launch, but nothing specific is yet available. Players in the beta will have the ability to buy cards for real money. The purchased cards will not be transferred to the full version of the game, however the amount spent in beta will be applied to new card packs and made available to the player once the game is released. Also those who do purchase cards will receive a special gift. You can sign up for the beta here.
