What’s better than one dot? How about 30 million.

The mobile puzzle game Two Dots has hit 30 million downloads, with people playing it over 5 billion times, developer Playdots Inc. revealed today. That makes the free-to-play game a big hit in a mobile industry that could reach $30 billion and exceed the console industry’s revenues this year, according to market researcher Newzoo.

Two Dots came out in May 2014 and is the sequel to the minimalist puzzle game Dots. It’s currently ranked #71 in the U.S. on App Annie’s list of most-downloaded iOS games.

“There’s more to come with Two Dots,” Paul Murphy, the chief executive officer of Playdots, told GamesBeat. “We have millions of loyal players that constantly want more content, features, and events, and our team is working hard to bring that to them. We’re also making more games, but in terms of Two Dots, we’re just getting started.”

Of those 30 million downloads, iOS is the leading platform, with 22 million. Android is next at 6.75 million downloads. Facebook has 1 million downloads, with Amazon getting 250,000.

Two Dots will launch soon in China, a difficult market for mobile gaming, with help of Chinese mobile publisher Tencent.
