Facebook Messenger is preparing to launch a new “Instant Games” platform that will let people play lightweight games against friends. Candy Crush maker King.com is already testing one of these Instant Games called “Shuffle Cats Mini” in New Zealand, TechCrunch has discovered. And other studios including Big Viking also appear to be prepping for the Instant Games launch.Facebook has been largely shut out of the native mobile gaming world by Apple’s iOS and Google’s Android. But by building games into Messenger by using it as a portal to mobile web apps, Facebook could create a new platform that drives Messenger engagement. Users could come to Messenger to play Instant Games, challenge friends via Facebook Messages, and potentially earn Facebook a cut of in-game purchases. Facebook did not immediately respond to a request for comment.Earlier today, The Informationreported that Facebook is building the Instant Games platform for asynchronous games that you can take turns playing with friends, not necessarily at the same time. Instant Games expands on the success of the chess,basketball, and soccer mini-games Facebook itself built for Messenger earlier this year by allowing third-party developers to build them too. Facebook plans to release a development kit or tool later this month, though developers haven’t been told if they’ll be able to charge for in-game purchases.
