Facebook’s done it again: In addition to the hidden chess game buried in Messenger, there’s a basketball game you can unlock also on your mobile phone. To play, open the Facebook emoji window, tap on the basketball emoji and send it to a friend. Then tap on the ball in your message and the basketball game will show up.
Swipe up on your phone to try to get the ball into the hoop. If you score 10 consecutive baskets, the backboard will start moving. Challenging!
