It is actually quite simple to get this party started. All you have to do is send the basketball emoji to a friend in a message and start a conversation. Once it’s sent, just tap the basketball imoji in the message conversation to start the game. The way it works is that a basketball will spawn at the bottom of the screen. Swipe up to put it in the goal. If it seems easy at first, just get ten shots in a row and you’ll see the twist: the goal starts moving.
We weren’t able to get this game working on all devices, but be sure to have the latest version of Messenger if you want to play around with this hidden little feature. If basketball isn’t really your style, then you can also check out that chess game we mentioned earlier by typing @FBChess into a conversation and hitting send.
