Blizzard is giving away free Hearthstone packs, celebrating 70 million players
Something else that happened with Journey to Un'goro is that Blizzard broke some of its records. Namely, in the number of players category. According to a post on the company's blog, Hearthstone just hit 70 million players. Of course, this doesn't mean that 70 million players are actively playing the game, but that there are that many registrations since Hearthstone's release.
In order to celebrate these two achievements, Blizzard is giving three free Journey to Un'goro packs to everyone. All you have to do, in order to claim your freebies, is log into the game during the month of May. Three packs might not sound as much for most hardcore players, but for casual ones that don't really want to spend money on IAPs, they're a pretty welcome gift.
