Facebook's Instant Games functionality for its Messenger app has only been available to users in the United States since it was unveiled back in November. However, the company aims to change that and has announced that it will be rolling out the feature to other territories starting today.

The feature itself allows friends to interact on Messenger in a completely different way by allowing them to play games online right within the app. According to Facebook, the feature should start to roll out to Facebook's 1.2 billion users, with some getting it earlier than others depending on their location. Facebook has of course been slowly adding new games to its roster, with the feature currently sporting over 50 games as of the moment.

The games that are available are also getting more progressive thanks to Facebook's new rich gameplay feature. One of the first games to take advantage of this is Zynga's very own "Words With Friends" mobile game. The turn-based multiplayer word game is akin to the classic board game "Scrabble," where players take turns in forming words in a crossword puzzle style grid. The game can, of course, be played directly on the Messenger app without having to launch any other software.

Another game that has been a big hit with US users is Blackstorm's "EverWing" video game, which is also the first game in the platform that supports Game bots. The scrolling shooter RPG is also accompanied by one of the most popular sports game in the platform, Miniclip's "8 Ball Pool."

According to GSM Arena, the majority of the games on the platform also have access to leaderboards and tournaments, which can be a great feature for users who want to compete with their friends on Facebook. The biggest advantage, of course, is being able to chat and share media during actual gameplay right within a single app. It has to be noted that the availability of some of the games will greatly depend on the compatibility of the device being used and the user's location.
