HEARTHSTONE PASSES 70 MILLION PLAYERS
Over 70 million people have played Hearthstone now, and that's not the only
milestone for the collectible card game.
Blizzard also announced that Hearthstone broke a record for most simultaneous
players at one time, thanks to the Journey to Un'Goro expansion. To
celebrate, the company is rewarding players — old and new — with card packs.
"We’re humbled and grateful that so many players have chosen to join us for
some Hearthstone fun," Blizzard said. "As our way of saying thanks, starting
today through the end of May, everyone who logs in will receive three free
Journey to Un’Goro card packs."
If you're curious what you might pick up for free, you can check out every

Back in 2015, Blizzard revealed that Hearthstone had reached 30 million
players. So the game has more than doubled its player base in almost exactly
two years.
