Facebook pitches games service to Messenger users

It has also introduced features that were previewed to developers at the annual F8 conference. These include rich gameplay features that allow developers to create better experiences and “game bots” to help re-engage gamers.
Facebook says that when developers start to take advantage of these new capabilities “everyone wins with more dynamic and engaging” gaming experiences.
Rich gameplay features such as turn-based games weave in leaderboards and tournaments, and offer more visually engaging and customisable game messages during play. Game bots help re-engage players by calling out new game options and encouraging competition with updates on the leaderboards.
One of the first games to take advantage of the gameplay features is Zynga’s Words With Friends. Words With Friends, one of the most popular games, is available as a feature-rich, turn-based game in Messenger.
People will begin to see new features as game developers start to incorporate the new capabilities with one of Instant Games on Messenger's biggest hits, Blackstorm's EverWing, being among the first to use game bots. “Depending on what device you use and where you are located, there are now up to 50 games titles available on Messenger, with more being introduced almost every week. We're also excited to be bringing the world's No 1 Pool game - Miniclip's 8 Ball Pool - to Instant Games very soon,” the company said.
“The new Instant Games on Messenger will roll out over the next few weeks worldwide for both iOS and Android.”
