A US bingo card is a 5 by 5 grid dealt from 1 to 75. The first column is drawn from 1–15, then 16–30, 31–45, 46–60, and 61–75. Five numbers come from each range. The centre square is free whether or not you went looking for a checkbox. The letters B, I, N, G, and O are not printed on the card, because the columns already are those ranges and a lettered header is easy to add with a pen if the caller is using lettered balls. This page opens in that mode. You do not type the numbers.
Make up to 12 cards at once. Each card is shuffled on its own, so two cards in one batch usually differ, and they will still share numbers. That is how a 75-ball hall works: the win is the arrangement, not a private set of integers. Press the button again for another table. Twelve is a page limit, not a party limit. The print dialog hides the article and the form, so the sheet is the cards. Save as PDF from that dialog if someone is joining from another room.
This is not a UK ticket. A 90-ball card is three rows by nine columns, fifteen numbers, and blank squares, with no free centre. That layout is on the UK 1–90 page. Typing 1 to 90 into the word box will not produce it, and it will not produce this column layout either. Words, including a starter list you replace, are on the word page. Photos stay on the device and belong on the picture page.
Calling is still a person. Write 1 to 75 down, or read from a stack of paper slips, and cross off what you have said. The page will not track the calls and it will not shout "bingo" for a player. A line is five marked squares in a row, a column, or a diagonal, including the free centre, under the house rule you announce before the first number. If your hall pays on four corners or a postage stamp, say so. The card does not know.
Check one card in the print preview before you print a stack. Numbers should sit one to a square, the centre should read FREE, and a column should not contain a number from the next range. If it does, you are not on this mode. The dropdown can be switched; this page only starts you in the 75-ball one.
