Celebrate March Madness by shooting a few hoops inside your Facebook Messenger app.

Facebook fb has updated its mobile app with a hidden basketball game that you can play inside a conversation with a friend, according to Android Central.

The steps are simple: update your app on either iOS or Android to the latest version, send your mate a basketball emoji, and then tap on it to load a secret game.

Swipe up on a basketball and try to get the ball into a hoop, which will move after you hit 10 points to offer a challenge greater than getting your NCAA Tournament bracket right.

This isn’t the first time Facebook has concealed a game inside Messenger. Last year, the site began offering a secret chess game for users who type @FBChess in a conversation window.
