Two kinds of bingo, one generator
Pick a mode and go. Number bingo gives you the classic 5x5 grid: a B column drawn from 1 to 15, I from 16 to 30, N from 31 to 45, G from 46 to 60, and O from 61 to 75. The center is a free space. That’s the version your grandmother played at the church hall, and it’s the one most callers reach for.
Custom bingo is the fun one. Paste a list of words or short phrases, one per line, and the grid fills with a random selection from your list. The sample card that loads is meeting bingo (you know the one: “you’re on mute”, awkward silence, “let’s circle back”). Swap in whatever you want.
How to make a card
It takes about ten seconds.
- Choose Number bingo or Custom words at the top.
- For custom cards, drop your list into the box. Twenty-four entries fill a grid with a free center; twenty-five fill it edge to edge.
- Decide whether you want that free middle square. Leave the box checked or uncheck it.
- Hit Generate. Don’t love the layout? Click New card and the grid reshuffles instantly.
- Print the card, or grab it as a PNG to drop into a doc or message.
Every card is built with a Fisher-Yates shuffle, so the order is genuinely random and never repeats a number or phrase on the same sheet. A standard number grid has somewhere around 5.52 x 10^26 possible arrangements. Translation: hand cards to thirty people and the odds of two matching are basically zero.
Where people actually use this
Teachers run it constantly. Sight-word bingo, multiplication-fact bingo, vocabulary review before a quiz: type the terms, print a stack, and you’ve got an activity that doesn’t feel like a worksheet. Kids beg to play it.
Baby showers love a custom card. Fill the squares with guesses and gifts (“diapers”, “onesie”, “someone cries”, “wrong-guess on the due date”) and people stay engaged through the unwrapping instead of checking their phones.
Then there’s the meeting. Remote-work bingo has become its own small genre, and the default list here leans into it. Print a few before the next all-hands and dare a coworker to get five in a row before someone says “let’s take this offline.”
Holidays round it out. Thanksgiving-table bingo, a Christmas-movie marathon card, New Year’s Eve predictions: the custom mode handles any theme you can list out. Game night with the family? Number bingo plus a bowl of buttons for markers, sorted.
Good to know
Nothing you type leaves your browser. The list, the cards, all of it stays on your screen, which matters if you’re building cards around inside jokes or company stuff.
Printing strips the buttons and the rest of the page, so you get a clean card on paper, nothing else. The PNG export draws the grid (header, free space, and all) onto a transparent-free white canvas at a crisp size, ready to share or print later.
Want a batch of unique cards for a crowd? Generate, print or save, then hit New card and repeat. Each pull is independent, so a room full of players each gets their own.
Questions people ask
How many cards can I make?
As many as you want. There’s no limit and no counter ticking down. Click New card, print or download, and keep going for as long as your paper holds out.
Are the cards actually random?
Yep. A Fisher-Yates shuffle picks the contents, so every arrangement is equally likely and you won’t see the same number twice on one card. Number grids alone have over 10^26 possible layouts.
Can I print these for free?
Of course. Hit Print and your browser’s dialog opens with just the card on the page. One card per sheet, ready for the photocopier if you need thirty.
What size should my custom list be?
At least 24 entries if you want a free center square, or 25 to fill every cell. More is better. A list of 40 or 50 phrases means the cards vary a lot more from one print to the next.
Can I save a card as an image?
Yes. The Download PNG button renders the current card to an image file you can text, email, or embed in slides. Works the same for number and custom cards.
Does it work on my phone?
It does. The grid scales down to fit a small screen, and the PNG download works on mobile browsers too. Printing from a phone depends on your device, but saving the image always works.
