Bingo Caller and Number Generator
Call 75-ball, 90-ball or 30-ball bingo one tap at a time, in type large enough for a projector, TV or phone, with a board that lights up every number called. Word games from the bingo maker open here from their share link, in the same order as the printed caller sheet.

Calling words from your own cards? No game loaded from a link yet. Make the cards in the bingo maker, then choose Open caller: the calls come out in the same order as the printed caller sheet.
How to call a number game
- Pick the game. 75-ball for cards with B-I-N-G-O columns, 90-ball for UK-style tickets, or 30-ball for quick speed bingo. One tap starts it with a freshly shuffled order.
- Call. Press Next call, or the space bar, Enter or the right arrow key. The number appears in large type, lights up on the board and joins the previous calls underneath. Undo, or the left arrow key, takes back a call made by mistake.
- Let it call for you, if you like. Start auto-call and choose a gap of 3 to 20 seconds; pause it the moment someone shouts. Tick Speak each call to have the device read the calls aloud as well.
- Check a winner. Read the numbers on the winning card back against the board. Every called number stays lit, so a check takes seconds.
- Play again. New game asks first, then starts a fresh order: the same kind of game or one of the other two.
How to call a word game from a link
- Make your cards first. In the bingo card generator (or on any themed page), build your list and set the number of cards. Print the PDF.
- Open the caller with the game. Choose Open caller in the generator, or open this page with the part of your share link after the # sign added to the end of the address. That part is the game: every word, the grid settings and the seed that decided the cards and the call order.
- Call. Each press of Next shows the next word in large type and adds the previous one to the history; Undo takes one back. Auto-call and spoken calls work here too. Read each word aloud as well; some players will be looking at their cards, not the screen.
- Check a winner. When someone calls "bingo", read their marked squares against the history. Every call so far is listed, so there is no arguing about whether "mistletoe" came up.
The calls come out in the same order as the printed caller sheet, so the screen and the paper always agree. Classic 75-ball number cards made in the generator open here the same way, with the board as well.
75-ball, 90-ball and 30-ball bingo
| Game | Numbers | Card | Wins |
|---|---|---|---|
| 75-ball | 1 to 75, lettered B to O | 5 x 5 with a free centre | Patterns: a line, four corners, a full card |
| 90-ball | 1 to 90 | 3 x 9 ticket with 15 numbers | One line, then two lines, then a full house |
| 30-ball | 1 to 30 | 3 x 3, with 9 numbers | A full card only |
75-ball is the usual game in the US and Canada. Each column draws from its own range (B 1 to 15, I 16 to 30, N 31 to 45, G 46 to 60, O 61 to 75), and every call comes with its letter, so players only search one column. The bingo card generator prints these cards: press Use numbers 1–75 instead in place of a word list.
90-ball is the usual game in the UK, Ireland and Australia. Each column of a ticket takes its own band of numbers (1 to 9 in the first, 10 to 19 in the second and so on, with 80 to 90 in the last), and one game runs in three stages on the same tickets. This page calls the numbers and tracks them; use 90-ball tickets you already have, since the generator makes square cards rather than tickets.
30-ball speed bingo is over in a few minutes, which suits a classroom warm-up or a quick round between other activities. To print cards, type the numbers 1 to 30 into the bingo card generator as your list, choose 3 x 3 and untick Free centre, then call the game here.
On a projector or TV
Plug a laptop into the projector or cast a browser tab to the TV, start the game, and press the Fullscreen button (or use the browser's own full-screen mode, F11 on Windows) so only the caller is visible. The current call is sized to be read from the back of a classroom or hall, with the board beside it on a wide screen. A presentation clicker works too: once you have pressed Fullscreen, its forward and back buttons call and undo. The caller also asks the browser to keep the screen awake while a game is in progress.
On a phone
The host can run the whole game from a phone: start it, tap for each call, read it out. That suits a family game or a small class where the host is moving around the room. The board sits under the call, so a check is a scroll away. If your phone still dims mid-game, turn off auto-lock for the length of the game. For a word game, keep the printed caller sheet beside you as a backup; the two always agree.
Why the link carries the game
Some bingo sites keep your game on their server and give you a code. This one does the opposite: the link is the only copy, and it lives on your devices. That means there is no account, nothing to delete afterwards, and the caller works in a hall with no Wi-Fi once the page has loaded. For a word game it also means the printed caller sheet, the on-screen caller and the cards can never disagree, because all three are rebuilt from the same seed and the same list. For a number game, the address holds the seed and how many calls have been made, so a reload picks up where you were.
One consequence worth knowing: anyone with the link can reproduce the order. For a party that is harmless. For a classroom quiz where the words are the answers, don't post the link where students can find it before the game.
Playing remotely
For a game over a video call, make one set of cards in the generator (words or 75-ball numbers), send players its share link and give each a card number. Then share this caller page from your screen. Players print their card or keep it open on screen and tick off calls on paper (the on-screen cards can't be tapped); you check winners against the board or the history. There is nothing for players to install or sign up for.
Frequently asked questions
Is the order of the numbers random?
Yes. Each game shuffles every number once from a random seed and then calls them in that order, so every number comes up exactly once and none is favoured. The seed is written into the page address, which is how a refresh carries on with the same order instead of starting a new one.
What if I lose my place or the page reloads?
Nothing is lost. A number game keeps its place in the page address, so a reload or a reopened tab comes back to the same call with the same order to come. A word game from the bingo maker is remembered in this browser, game by game. On a different device, open the same link and press Next until the count matches; Undo steps back one.
Can I run the caller on one screen and follow along on another?
Yes. For a number game, copy the page address from the screen running the game and open it on your phone: it opens on the same call, with the same order to come. For a word game, open the same share link on both. After that each device keeps its own place, so pressing Next on one does not advance the other. Either advance both in step, or keep the phone as your private record and run the calls from the big screen.
Can it read the calls out loud?
Yes. Tick Speak each call and the browser reads every call in your device's own voice: "B, 7" in 75-ball, the number alone in 90-ball and 30-ball, and the word itself in a word game. Choose a slow, normal or fast voice. It stays off until you turn it on, and the option is hidden on browsers that have no voice to offer. In a big or noisy room, call out loud as well; a laptop speaker doesn't fill a hall.
How fast should auto-call go?
For number games, one call every 6 to 10 seconds suits most rooms. Slow down for children, newcomers and anyone playing several cards at once. Word games need longer, about 10 to 15 seconds for adults, because players read every square. Pause auto-call as soon as someone shouts, and check the card before you carry on. The guide to hosting a bingo game covers pace in more detail.
Why does a word game need a share link?
Because nothing is stored on a server. The link holds your word list, settings and the seed that fixed the card and call order, so the caller can rebuild the exact game. Open the link on any device and the calls come out in the same order as the printed caller sheet.
Can I call in a different order next time?
Yes. In a number game, press New game for a fresh shuffle. For a word game, press Shuffle in the generator and you get a new seed, new cards and a new call order, all captured in a new share link. Keep the old link if you want to replay a game exactly.
Does the caller work without the internet?
Once the page has loaded it needs no further connection, which matters in church halls and classrooms with patchy Wi-Fi. Open it before you walk in, and don't close the tab. Some browsers fetch their voices online, so if you rely on spoken calls, try them in the room first.
