Blizzard launches Hearthstone open beta for Windows and Mac

Blizzard's digital collectible card game Hearthstone: Heroes of Warcraft has entered open beta, and is now available as a free download for Windows and Mac in North America.

Originally announced at PAX East in 2013, Hearthstone saw a lengthy closed beta test in advance of today's launch. Ports for iOS and Android are set to premiere later this year.

While Hearthstone is currently available only in North America, Blizzard announced that players in other regions can expect to join the open beta "within the next few days."
