How the generator builds every card
Every card follows the classic American 5 × 5 B-I-N-G-O layout: five numbers under B (1 to 15), five under I (16 to 30), four under N (31 to 45, around the FREE space in the center), five under G (46 to 60) and five under O (61 to 75). Within each column the numbers go up from top to bottom, so players can scan their cards as balls are called.
Each card is drawn on your device with your browser’s cryptographic random number generator. With numbers sorted in each column there are more than 111 quadrillion possible cards, and the generator still throws out any duplicate within a print batch. Planning a December party? The Christmas bingo cards page prints the same cards with a small tree next to the name.
What you can customize, and how to print bigger batches
People looking for custom bingo cards often want them to carry the name of their party or group. Here you can set the event name printed at the top of every card, next to its card number. The 24 squares always hold standard 1 to 75 numbers rather than words or photos, so your sheets work with any 75-ball caller.
This page prints up to 30 cards at a time, the same number Tombingo’s free plan gives each event. If you need more paper cards for a school gym or community hall, run a second or third batch and add “Batch 2” or “Table B” to the event name: every batch starts again at card 1, and the name tells them apart when someone shouts “Bingo!”.
Hosting a crowd or remote players? Run your bingo night on Tombingo
Printed sheets work well around a kitchen table. At a school bingo night, a club social or a team event with remote colleagues, paper-only play runs into three problems: remote guests can’t grab a sheet, people in the back row can’t see which numbers are out, and checking a bingo by reading every number aloud stops the whole room.
When you create a free event on Tombingo, you run the game from your organizer console: a read-only hall screen goes on the TV or projector, guests open a link on their phones and see their cards marked live with nothing to install, the console checks every claimed bingo by card number and shows any missing balls, and between rounds you can raffle a random card among the cards in play. You can also add your organization’s logo and color, choose from 10 built-in patterns or draw your own, and use live chat and announcements.
For guests who prefer paper, the console prints the event’s cards to PDF, 4 per sheet, each with its number, a unique code and a QR code. A guest scans the QR or types the code in the event room to register that card to their name. Cards from this free page have no code, so they can’t be registered in an event.
Events are free for up to 30 cards, and passes for bigger crowds start at USD 9 on the pricing page. More on the Tombingo home page.
