🎟️ Bingo Online: how to play in rooms with up to 60 players

By Miguel Arechaga

MundoSudoku's Bingo is the classic 90-ball game: a card with 15 numbers spread across 3 rows and 9 columns, balls called out loud one at a time, and two ways to win: line (complete a full row) and bingo (complete the whole card). You can play solo against the clock to practice, or join an online room and compete in real time with as many people as you want, with no room to create and no code to share. Here's exactly how the rooms work.

How to join an online room

1. Go to the Bingo page and tap the «🌐 Online Rooms» button.
2. That's it: MundoSudoku instantly drops you into a room that's already running (or creates a new one if needed), with no name, code, or waiting for anyone to start required.
3. You'll see the list of players in your room in real time, and who's getting a line or bingo.
4. If you join after the game has already called some balls, your card automatically catches up with the numbers already out.

What happens if the room fills up?

Each room holds up to 60 players. As soon as a room fills up, or ends because someone already got bingo, MundoSudoku automatically creates a new room for the next person who taps "Online Rooms", with nothing for you to do. So even when lots of people are playing at once, you're never left out of a game.

How to play once you're in the room

• Balls (1 to 90) are called automatically every few seconds, out loud, and also shown on screen along with a history of the most recent balls.
• Marking is manual: when a number on your card is called, that number gets highlighted so you can tap it and mark it yourself. It doesn't mark automatically, so you need to pay attention.
• As soon as you complete a full row you get a line, and as soon as you complete the whole card you get bingo and win the game. Other players can see in the room list who's getting a line or bingo.
• If someone else completes bingo before you, the game ends for everyone and the winner is announced.

Do I need to sign up?

No account or signup is needed to play in an online room. If you're signed in to MundoSudoku, other players will see your username; if not, you're given a guest name automatically. Just tap "Online Rooms" and you're in.
