Facebook recently announced there are more than a billion people using Messenger, so Pocket-lint thought we'd round-up some of the most interesting things you can do with the messaging app that's clearly taken over the world.

However, we're not going to cover basic things like how to send a message, photo, video, sticker, or emoji - nor are we going to discuss how to place a video/voice call. Those are functions that pretty much everyone knows how to use at this point. Instead, this handy guide, which is for the Android and iOS app, is all about those hidden tips and tricks, such as how to start a game of chess or interact with a bot.

Let us know in the comments if you know other tips and tricks worth including, as we plan to update this piece over time.

This one is for Android only. If there is a Messenger conversation you want to access quickly, you can create a quick-access shortcut on your home screen. Just long-press on any conversation under the Home tab to prompt a pop-up menu, where you'll find the option to "Create shortcut", Select that to create a shortcut on your phone's home screen. It basically makes that Messenger conversation just a tap away.

Earlier this year, Facebook said bots were coming to its Messenger app. Well, you might not have realised this, but they're already available.

Many bots have actually been available for months. It's hard to tell, however, because they're buried in the Messenger app and hard to locate. But they aren't hard to use. You can use them to play trivia and games like hangman. You can also order flowers or hail an Uber. The possibilities are endless. Bots are designed to bolster your chat experience and make your life easier.

Check out Pocket-lint's step-by-step guide to find out more about Messenger bots, including what they are and how you can find them.

If you work in front of a computer most of the day, you can use Messenger without going to the Facebook.com homepage. Just go to Messenger.com. Unfortunately, this web app doesn't pack all the functionality of the mobile app.
