Google's new social networking site is working hard to give Facebook a run for its money.

Google Plus is adding games to its user experience.

Google's senior vice president of engineering, Vic Gundotra, made the announcement on Google's blog. One feature of the games is that the games will be easy to hide on the screen and easy to bring back up.

"Games in Google+ are there when you want them and gone when you don't," Gundotra wrote.

Google Plus games include Zynga Poker, Sudoku, Dragons of Atlantis, Angry Birds and Monster World.

Facebook, meanwhile, is revamping its own gaming experience. Jared Morgenstern, the company's product manager for games and credits, outlined some of the new features of the gaming process on the company's blog. These features include a bigger screen for a more "immersive experience" and keeping one's favorite games and apps at the top of their bookmarks on their homepages.

A separate stream will allow Facebook users to see which games their friends are playing. If users see something that interests them, all they have to do is click.

"The best way to find new games is through friends, and now you'll have more opportunities to see what they're playing," Morgenstern, wrote.

"You'll begin seeing games that can expand to full screen, such as CityVille, Zoo World, Monster World, and Mystery Manor in the coming days," he wrote.

Google Plus is still in development, but it has already sparked interest. The site had two million users two weeks after its limited trial launch.
