A bingo card is a 5 by 5 grid. Someone calls an item, players mark a square, and a finished line is the claim. This page builds the grids. It does not host the party and it does not call the items for you. You choose words, the usual 1–75 numbers, or pictures, you choose how many cards to lay out, and you print them. The shuffle runs in the browser, so two people who press the button do not share a deck, and the words you typed are not stored on a server.
Word cards are the flexible case. Put one entry on each line: a baby item, a vocabulary word, a film title, a coworker's prediction. Blank lines are ignored. "River" and "river" are the same entry, so a list copied twice does not pretend to be longer than it is. With the free centre ticked, the middle square says FREE and the card needs 24 other entries. Untick it and every square, including the middle, is a word, so you need 25. The box above starts with a 30-word placeholder list so you can press Make cards once and see the layout before you replace the list with your own. Twelve cards is the limit on one page, which is enough for a small table. Reload or press the button again for another batch. Each press shuffles again.
Number cards follow the 75-ball layout players expect even when the letters B-I-N-G-O are not printed on the grid. The first column is drawn from 1–15, then 16–30, 31–45, 46–60, and 61–75. Five numbers come from each range, and the centre is free whether or not the checkbox is ticked. The checkbox hides in that mode so it does not look like a setting that still applies. You do not type the numbers. If you wanted a card of ages or table numbers instead, use word mode and type those figures as lines. They will not be forced into the 1–75 columns. Dedicated pages open in one mode already: US 1–75, UK 1–90, and words from your own list.
Picture cards use files you pick, or a set of numbered sample icons drawn on this page. The sample set exists so you can try the layout without hunting for 24 photos. Your own pictures need to be at least 24 files with a free centre, or 25 without. The same file cannot fill two squares on one card. Photos are read with the browser's file reader and painted into the squares. They are not uploaded, not resized on a server, and not kept after you leave. A very large photo album will make the tab heavy because every image is held in memory as a data URL. Pick the pictures you actually want on the cards, not the whole camera roll. The themed picture bingo page opens with that mode already selected.
Printing is the browser's print dialog. The button labelled Print or save as PDF calls it. Headers, the explanation, the form, and the footer are left off the sheet so you are not paying for a page of instructions. Two cards sit side by side on a typical sheet. If a card breaks across pages, use the dialog's scale, or make fewer cards at a time. Save as PDF when you want a file to send. The PDF is produced by your browser or operating system, not by an online converter. Check one card in the preview before you print a class set. A word that is too long for the square wraps. A phrase of six words will be cramped. Shorten the line, or accept a smaller type size on that square.
Fairness is just the shuffle. Every card in a batch is an independent draw from the list you supplied, not a carefully blocked set where each word appears the same number of times across the room. For a classroom game that is usually fine. For a competition with a prize, glance at the cards and regenerate if one player somehow received a much easier line. The page will not deal a caller sheet. Write the master list down, or read it off the original textarea, and cross items off as you call them so you do not repeat.
Two themed lists are already filled in, if you do not want to invent thirty lines. Baby shower bingo opens with a list of ordinary shower words. Classroom vocabulary bingo opens with school words you can replace with this week's spelling list. Both are ordinary word cards with a head start. Edit anything that does not fit the party, then make the cards. The free centre is on by default because that is what most printed cards do. Turn it off when you want the middle square to be in play.
