Master this multiplayer bingo minigame extravaganza and get crowned as the Qing o’ Bingo! Every 30 seconds, a new set of bingo balls drops down to the bottom of the screen. The balls are numbered between 1 and 15. If you see a ball number that matches an empty bingo-card slot, click the slot, and the ball will automatically fill it. Joker balls are indicated with a jester’s hat.
