A free bingo card generator with unique cards and a call sheet
This bingo card generator makes as many unique bingo cards as you need and lays them out for printing. Choose classic 75-ball bingo — five columns headed B, I, N, G and O with numbers 1–15, 16–30, 31–45, 46–60 and 61–75 and a free centre square — or build your own game: numbers in any range on a 3 × 3, 4 × 4 or 5 × 5 grid, or words of your choosing for vocabulary practice, baby showers, office icebreakers or a themed party.
Every set comes from a seed. Type any word or number as the seed and the cards are generated from it the same way every time, so you can reprint a lost card weeks later, or let two helpers print identical sets on different computers. A call sheet page lists every item in a random calling order with tick boxes, which doubles as the master list for checking a winning card.
Generation, layout and the PDF all happen in your browser; nothing is uploaded.

Bingo Card Generator features
Classic 75-ball layout
Column-correct numbers under B-I-N-G-O, five per column, with a free centre — the format used in North American bingo halls.
Three grid sizes
3 × 3 for young children or quick rounds, 4 × 4 for a middle ground, 5 × 5 for the standard game.
Numbers or words
Any numeric range (1–90 for a British-style call list, 1–20 for maths practice) or a word list, with long words wrapped inside the cell.
Guaranteed unique cards
Each card is compared with every card already generated; duplicates are discarded and regenerated, so no two players hold the same card.
Seeded and reproducible
The seed, mode and grid size determine every card and the calling order. The seed is printed in the corner of each card.
Call sheet with tick boxes
An extra page lists all items in a shuffled calling order, numbered, so the caller can work down the list and verify claims.
How the cards are generated
The seed text is hashed (xmur3) into a 32-bit number that starts a small, fast pseudo-random generator (mulberry32). Each card draws numbers with a Fisher–Yates shuffle: in 75-ball mode the shuffle runs separately on each column’s fifteen numbers and takes the first five, so column ranges are always respected; in the other modes the whole pool is shuffled and the first N² items fill the grid row by row. The calling order is a final shuffle of the full pool.
Because every step depends only on the seed, the same seed gives the same cards on any device, and card 1 of an 8-card set is card 1 of a 50-card set, so you can print extras for latecomers.
Bingo variants and how to set them up
| Game | Settings here | Notes |
|---|---|---|
| 75-ball (US, Canada) | Classic 75-ball, 5 × 5, free centre | Lines, four corners, X or full house (“blackout”) |
| 90-ball call list (UK, India tambola) | Numbers 1–90, 5 × 5 | Real 90-ball tickets use a 3 × 9 strip; this gives square cards with the same numbers |
| Classroom maths bingo | Numbers 1–20 or 1–100, 3 × 3 or 4 × 4 | Call the sums (“7 + 5”) and let pupils find the answer |
| Vocabulary or picture bingo | Words, 3 × 3 or 4 × 4 | Call the definition, translation or show the picture |
| Baby shower / wedding bingo | Words, 5 × 5, free centre | Gift names, song titles or “things the couple will say” |
Printing tips
- Four cards per A4 or Letter page are about 90 × 130 mm each — comfortable for daubers; two per page gives large cells for younger players; one per page is poster-sized for the caller.
- Print on plain paper and hand out pens, or use 120 gsm card if cards will be reused with counters. Keep the call sheet (the last page) for the caller.
- For prize draws at the same event, the raffle ticket generator numbers tickets with stubs, and the random number generator picks the winner. Shuffle any list with the list randomizer.
Bingo Card Generator FAQ
Are the bingo cards really unique?
Yes. The generator keeps a record of every card in the set and throws away any repeat. With 75-ball bingo the number of possible cards is in the hundreds of billions, so repeats are vanishingly rare; with a small word list and a 3 × 3 grid the tool tells you if it cannot make as many distinct cards as you asked for.
How do I check a winning card?
Compare the claimed numbers with the ticked items on the call sheet. Each card carries its number and seed in the corner, so you can regenerate the set and inspect that exact card.
Can I make bingo cards with pictures?
The cells hold text, so enter the picture names (“cat”, “bus”, “umbrella”) and the caller shows or describes the picture. Words wrap onto up to three lines inside a cell.
What is the free space for?
The centre square of a 5 × 5 (or 3 × 3) card counts as already marked, which makes lines through the middle slightly easier and keeps traditional 75-ball cards familiar. Untick “Free centre square” for a harder game; 4 × 4 grids have no centre and never use it.
How many cards can I generate at once?
Up to 100 cards per download, which is 25 pages at four per page plus the call sheet. Run the generator again with a different seed for a second batch; seeds give different cards, so mixing batches is safe.
Does the bingo card generator work offline?
Once the page has loaded, cards and PNGs are generated locally; the PDF library is fetched the first time you press Download PDF.
