To make classic number bingo cards: turn on fill by column and give each column its own range — B 1-15, I 16-30, N 31-45, G 46-60, O 61-75. Every card is randomized separately within those ranges, so a room full of players each get a different card that still plays by the standard rules. The starter below has all five ranges filled in already.
Classic bingo is a numbers game. Each column draws from its own range — B from 1 to 15, I from 16 to 30, N from 31 to 45, G from 46 to 60, O from 61 to 75 — and that structure is what makes a called number like "I-24" mean something. A generator that shuffles one flat list of 75 numbers across the whole grid does not produce a real bingo card; it produces a grid of numbers that happens to look like one.
If numbers land anywhere, a caller announcing "B-7" has to let players hunt the whole card, and any pre-printed calling equipment stops matching. Keeping each column in its own range is the difference between a card you can run a real game with and a novelty print-out. That is why this page exists: the generator can now fill each column from its own list, so the standard ranges are simply five blocks of numbers.
Each card is randomized on its own. Order inside every column is shuffled per card, so printing forty cards gives forty different arrangements that all still obey the B-I-N-G-O ranges. Nobody ends up holding a duplicate.
The centre square of a 5 × 5 number card is traditionally free, and that is the default here — it takes the middle slot of the N column, exactly as a printed card does. You can turn it off, rename it, or keep it; on grid sizes without a true middle square the generator places it randomly instead.
75-ball is the classic, but it is not the only way to run a room. A 3 × 3 card with three ranges makes a fast round for children or a warm-up game, and a 4 × 4 suits a shorter session. Set the card size first and give each column a block that matches — the counter under the square list tells you how many entries the size you picked needs.
Number cards are usually printed in bulk, so the defaults are built for it: Eco Print is black and white with minimal ink, landscape puts two cards on a page with a cut line down the middle, and a single PDF holds the whole batch. If you would rather the cards match a venue or a fundraiser's colours, the custom colour picker sets the background, the numbers, the title bar and the free space, and checks the contrast as you go so the numbers stay readable across a hall.
The five column ranges are already blocked out below, separated by blank lines. Open the generator and it arrives set to fill by column on a 5 × 5 card — pick a look and print.
Nothing is sent anywhere — the list is held in this browser and handed to the generator when you continue.
