Bingo Card Generator

This generator makes standard 5×5 bingo cards you can print, download as a PNG, or hand out as a link. It runs entirely in your browser — nothing you type is uploaded, and there is no account, no watermark and no card limit beyond the 24 per batch the print layout is built for.

The two modes

Numbers produces the classic 75-ball card that bingo halls, fundraisers and classrooms use. The five columns are fixed to their traditional ranges: B draws from 1–15, I from 16–30, N from 31–45, G from 46–60 and O from 61–75. Each column draws five numbers from its own fifteen, without repeats, so a called number like "I-22" can only ever appear in one column. That is what makes a called-number game work: the caller announces the letter and the number together, and every player checks a single column.

Words & Phrases swaps the numbers for a list you write yourself — one entry per line. This is the format people mean by "meeting bingo", "road trip bingo", "baby shower bingo" or a classroom review game: instead of waiting for a number to be called, players mark a square when the thing on it actually happens. Blank lines are ignored and duplicates are dropped case-insensitively, so pasting a messy list is fine. The tool ships with a sample list of 25 video-call clichés if you want to see the shape before writing your own.

The free space

The centre square is marked FREE by default, which is the standard rule — every player starts with the middle of the board already covered, so the four lines through the centre need only four marks instead of five. With the free space on, a numbers card draws only four numbers in the N column, and a word card needs 24 entries. Turn it off and the centre becomes an ordinary square: the N column draws its full five, and a word list needs 25. The counter beside the word box tells you which target applies and how far off you are, and the cards stay blank until the list is long enough rather than silently repeating entries to fill the grid.

How many different cards are there?

Enough that you will never hand out two the same by accident. Each of the B, I, G and O columns is an ordered choice of 5 numbers from 15, which is 360,360 possibilities, and the N column with a free centre is an ordered choice of 4 from 15, or 32,760. Multiplied together that is about 5.52 × 10²⁶ distinct cards — 552 septillion. Turning the free space off raises it to roughly 6.08 × 10²⁷. Even printing the maximum batch of 24 cards at once, the chance that any two of them collide is around 5 × 10^-25.

Word cards are more constrained, because they are limited by your list. A pool of exactly 24 phrases still yields about 6.2 × 10²³ arrangements — every card holds the same 24 phrases, but in a different order, which plays perfectly well. Add a few spares and the cards start to differ in content too: a pool of 30 gives roughly 3.7 × 10²⁹. For a group where people can see each other's cards, a pool of 30–40 is a good target.

Printing

The Print button opens your browser's normal print dialog with a black-and-white layout: site chrome, buttons and colours are dropped, each card gets a heading, and page breaks fall between cards so nothing is sliced in half. Choose one or two cards per sheet — one card fills a page nicely for a wall or a table, and two per sheet halves your paper for a big group. Pressing Ctrl+P (Cmd+P on a Mac) gives exactly the same result as the button, because the printable version is always present in the page rather than being assembled when you click.

Dark mode does not follow the cards onto paper. The printed layout uses fixed black-on-white regardless of the theme you are browsing in, so you never get a page of solid black ink.

PNG download

Every card has its own PNG button, which renders that card at print resolution and downloads it. Use this to drop a card into a slide deck, a chat message, a newsletter or a printed handout laid out somewhere else. The image is drawn fresh from the card data rather than screenshotted, so the text stays crisp at any size, and it uses the same black-on-white treatment as the print view. If you set a card title, it appears above the grid in the image and in the filename.

Sharing the exact same cards

The link in your address bar always describes the current set, and Copy link puts it on your clipboard. Open it anywhere and you get the identical cards, not a fresh random batch — which is the difference between "here's a bingo generator" and "here's our game". That works because a card is computed from a numeric seed, and it is the seed that travels in the link, not the 25 squares. A 24-card link is no longer than a one-card link.

Everything after the # in the URL is a fragment, which browsers never send to a server. Your card titles and your word list stay on your machine even when you share the link — the person you send it to decodes it in their own browser. Hitting Regenerate picks a new seed and rewrites the link, so the old link keeps working and still shows the old cards.

Ideas for a word list

Anything with a predictable set of recurring moments works. Meetings ("someone is on mute", "can everyone see my screen"), road trips (a red barn, a cow, an out-of-state plate), holiday dinners, sports broadcasts, a film you have all seen too many times, a training course, a conference keynote, or a classroom review where each square is a term students have to find an example of. Aim for squares that are likely but not certain: a card where every square gets marked in the first ten minutes is no more fun than one where nothing does.
