SAN FRANCISCO: Facebook on Tuesday unveiled "Instant Games" allowing users of the world´s biggest social network to play from its Messenger application or directly on their news feeds. The new games effort could be a step toward eventually monetizing Messenger, which now has more than one billion users. "This new games experience allows people to easily discover, share, and play games without having to install new apps," said Facebook product manager Alissa Ju in a blog post announcing the initiative.
