Wait, what? A hidden chess game in Facebook Messenger?

If you are a chess lover who also happens to be a user of Facebook's Messenger app (which crossed the 800 million active users milestone last month), here's some thing of your interest - aside from chatting, the mobile messaging app also allows you to play the game with your friends.

The feature was discovered by a Reddit user. While we don't know when it was first introduced in the app, it has been there for at-least over a month now given that the Reddit thread itself is that much old.

As per the information shared on the thread, you can start playing chess with someone by typing @fbchess play and end it by typing @fbchess resign - head to the Reddit link below for other instructions on how to play the game.
