Facebook Messenger can be a great way to stay in touch with your friends. The service works on desktop computers, as well as iOS and Android, making it a universal way for people to stay in touch no matter what kind of computer (or phone) they use or even where they are in the world.

While most people probably know the basics of sending and receiving messages on the service, Facebook Messenger has a number of hidden features that many users don’t even know are available. You’ve probably heard friends refer to them as “hidden messages on Facebook,” but in reality, many of these features involve more than just a simple message. These features range from secret chats to hidden games.

Let's take a look at what the features are, how they work, and how you can make the most of them.

If you want to chat without the distractions of the rest of Facebook, run Facebook Messenger in its own window. That means you can chat with friends on the service all day long without worrying about wasting an hour watching videos of a friend's new puppy.
