Proper 75 ball columns
The B column holds 1 to 15, I holds 16 to 30, N holds 31 to 45, G holds 46 to 60 and O holds 61 to 75. That is the standard arrangement, which matters if you are calling from a set of balls or an app rather than from the caller sheet.
A 1 to 90 version is also available for UK style bingo, with three rows of nine and the usual blank squares. Switch range in the panel if that is the game you are used to.
Card count and duplicates
Thirty cards per run, each verified against the others so no two are identical. For a bigger group, generate twice. With 75 ball cards the odds of a genuine duplicate are tiny anyway, but the generator checks rather than trusting the odds.
Two cards print per A4 sheet by default, which keeps the numbers large enough to read across a room. One per sheet is available if you are playing with older players or in poor light.
Why a number game for a Christmas party
Picture bingo needs someone to design and call items, and it suits children. Number bingo needs nothing except the cards and works with any crowd, any age and any noise level, which is why care homes, social clubs and large family gatherings tend to prefer it.
Questions
- Are these standard 75 ball bingo cards?
- Yes. B holds 1 to 15, I holds 16 to 30, N holds 31 to 45, G holds 46 to 60 and O holds 61 to 75, with a free centre square, so they work with any standard ball set or caller app.
- Is there a 1 to 90 version for UK bingo?
- Yes. Change the range in the panel to get 90 ball cards with three rows of nine and the usual blank squares.
- How many cards do I get?
- Up to thirty per print run, each checked against the others so there are no duplicates. Generate again for a larger group.
- Can I check a winning card afterwards?
- Yes. The caller sheet is a full grid of all the numbers that you cross off as you call, which lets you verify a claimed line or full house straight away.
