Bingo caller online with voice
This bingo caller replaces the cage and the balls: press “Call a number” and a number that has not come up yet is drawn, read aloud and marked on the board. It works for 75-ball bingo with the letters B-I-N-G-O, for 90-ball bingo as played in the UK, or for any range up to 100 – with an automatic mode for hands-free calling.
Source: Wikipedia – Bingo (American version): 75 numbers, columns B 1–15, I 16–30, N 31–45, G 46–60, O 61–75, free centre square, role of the caller. Updated: .
How it is calculated
The bingo caller draws every number exactly once, in random order, and keeps the board of called numbers for checking a winning card. You need nothing but this page and the cards.
How to call bingo with this page
- Check the number of balls: 75 for 5 × 5 cards with B-I-N-G-O, 90 for tickets with three rows, or any other number up to 100.
- Press Call a number. The number appears large, is read aloud and is marked on the board.
- Prefer not to tap? Auto calls a ball every 4, 6, 8 or 12 seconds until you stop it.
- Someone shouts “Bingo!” or “House!”? Compare the card with the board: every marked number has been called. “Previous numbers” shows the last five.
75-ball and 90-ball bingo
| Game | Numbers | Card | How a number is called |
|---|---|---|---|
| 75-ball (USA, Canada) | 1 to 75 | 5 × 5 grid with a free center square, columns B, I, N, G and O | letter and number: “B 12”, “O 70” |
| 90-ball (UK) | 1 to 90 | ticket with 3 rows and 9 columns, 5 numbers per row | the number only |
In 75-ball bingo each letter covers 15 numbers: B is 1 to 15, I is 16 to 30, N is 31 to 45, G is 46 to 60 and O is 61 to 75. Need cards? The bingo card generator makes and prints them, also with words or pictures for the classroom.
No repeats, no favorites
Each ball comes up once. On every call the browser picks one of the remaining numbers with crypto.getRandomValues(), the secure random number generator of your device. With 75 balls, each number has a chance of 1 in 75 (about 1.33%) on the first call; with 90 balls it is 1 in 90 (about 1.11%). When 10 balls are left, each has 10%. Nothing is sent to a server.
Voice, big screen and playing at a distance
- Voice: the number is spoken by a voice installed on the phone or computer. If the device has no English voice, the caller plays a chime.
- Big screen: connect the device to a TV or projector and press the full-screen button; ball and board can be read from the back of the hall.
- At a distance: share your screen in a video call. The “Share” link carries the numbers already called, so a player can check them later.
Where it is used
Teachers call vocabulary or times-table bingo, families play on holidays, and clubs and care homes run an afternoon session with a caller everyone can see. The page is meant for games played for fun: it has no stakes and handles no money. For the Indian version with its own tickets, see the tambola number generator.
The game is not lost
Called numbers are stored in the browser: if the screen goes dark or the page is closed, the board comes back as it was. “Undo” puts the last ball back; “New game” starts from zero after a second tap.
Frequently asked questions
How does the online bingo caller work?
Press “Call a number”. The caller picks a number that has not come up yet, shows it large, reads it aloud and marks it on the board. No sign-up is needed.
Does it work for 75-ball and 90-ball bingo?
Yes. Set the number of balls to 75 or 90 – or any whole number from 10 to 100. With 75, each number is called with its column letter B, I, N, G or O.
Does the bingo caller have sound?
Yes. It reads the number with a voice installed on your device; without an English voice it plays a chime. Untick both sound options to play silently.
Is there an automatic mode?
Yes. Press “Auto” and choose one ball every 4, 6, 8 or 12 seconds. Press again to stop. It also pauses when you switch tabs.
Can a number be called twice?
No. Each ball is drawn once per game. After “New game” all numbers are back.
How do I check a winning card?
Compare the numbers on the card with the board: marked numbers have been called. The full order of the calls is kept on the device.
I called a number by mistake. What now?
Press “Undo”: the last ball goes back and can come up again later.
Can I use it on a TV or projector?
Yes. Connect your device and switch to full screen. For remote games, share your screen in the video call.
