Hearthstone’s 30M players is great, but its revenues are even more impressive

It turns out that releasing a free-to-play game on smartphones can help you make more money.

Publisher Blizzard revealed today that more than 30 million people have played its online card battler Hearthstone on PC, Mac, smartphones, or tablets. And that’s a pretty decent number — although it doesn’t reveal exactly how active the community is on a monthly or daily basis. But that doesn’t really matter because the game is obviously catching on with many of the people who do play it, and you can tell that’s the case by how well it’s performing on the top-grossing charts on iOS and Android — and it’s doing quite well.
