Facebook users can now play Pac-Man on Messenger app

(Reuters) - For users hooked on to Facebook's Messenger app, it's game on. The social network on Tuesday rolled out a feature that allows users to play hugely popular games such as Pac-Man and Space Invaders, the company's latest attempt to get users spend more time on its messaging app. Facebook made Messenger a standalone app in 2014, a move that initially irked many users.
