Hearthstone developer Blizzard announced a “Recruit a Friend” feature that is exactly what it sounds like: players can ease their friends who haven’t played Hearthstone into the game. And if you use this feature and your friends downloads the game, you can win a free Shaman hero and booster packs.
Players can access a “recruitment link” here they can send to a friend, and they get the reward after the friend plays the first few introductory missions. It’s a classic business move, really helps the product grow by enticing users to share it. Nevertheless, free booster packs is not a bad idea.
