How to play

With printed cards

Print as many cards as you need (up to 30) and the caller sheet. Every card is different.
The caller reads the squares from the caller sheet, one at a time, and ticks each one. Read the fun fact too, if you like.
Players mark a square when it is called. Coins, cereal, buttons or a crayon all work. The star in the middle is free.
The first player to fill a whole row, column or diagonal shouts "Bingo!" The caller checks that line against the ticks on the caller sheet.

Ways to win

Any line: a full row, column or diagonal. Quick games of about ten minutes.
Four corners: the four corner squares.
Blackout: every square on the card. Longer games, good for a big group.

With a TV and phones

Open this set on a TV or laptop and pick how to win and how fast to call.
Players go to roomfulbingo.com/join on their phones (or scan the QR code) and type the four-letter room code. Each phone gets its own card.
The TV calls each square with its fun fact (it can read them aloud, too). Players tap a square to mark it.
When a card has a winning line, its BINGO button lights up. The game checks it against the calls and shows the winner on the TV.

Printed cards and phones can play together: when someone shouts "Bingo!" on paper, the host types the card number and the TV checks it. It works the same way as Roomful Trivia: no app and no accounts.
