Facebook’s social-gaming empire is growing.

The social-networking website, which has more than 1 billion members, said the number of people paying to play games on its service rose 24 percent from a year ago, according to an emailed statement. Desktop game users on the site jumped to more than 250 million from 235 million in October. The company paid a total of $2 billion to developers in 2012.

Facebook Chief Executive Officer Mark Zuckerberg is taking steps to improve the gaming experience by encouraging more developers to join the site after previously depending largely on Zynga Inc. to bring in people who want to play. The executive has spent recent years striving to win back users who initially were alienated by the sometimes intrusive ways game makers could market and distribute their wares.

“This is an important category for Facebook,” Sean Ryan, Facebook’s director of game partnerships, said at the Game Developers Conference in San Francisco. “It’s good for Facebook. It’s good for users.”

The company takes a percentage of the fees paid by users to game companies and garners revenue from developers that use advertising to boost exposure on the service.

More than 100 developers generated more than $1 million each in revenue on Facebook last year, the company said, and most of the top developers received record revenue from payments.

Zuckerberg and Ryan held a dinner meeting in late 2012 with executives from top makers of social games to discuss ways to increase usage and sales on the social network.

No representatives of Zynga were present.

Zynga, an early beneficiary of Facebook’s gaming platform, aggressively marketed its titles, and some users grew unhappy with the barrage of marketing from its programs, such as FarmVille. More recently, Facebook has distanced itself from Zynga and tried to emphasize a greater variety of games. It’s also put stricter controls on how much developers can market to users.

“If you’ve got games that are a little bit different from what’s out there, we’re happy to figure out how to make the platform work for you,” Ryan said. “The diversity continues to grow on the platform.”

Separately, the company said it’s expanding Facebook Exchange, a service that lets advertisers target users based on their Web-browsing history.
