What this tool does
Standard 75-ball bingo puts each column on its own range of numbers — B from 1 to 15, I from 16 to 30, N from 31 to 45, G from 46 to 60 and O from 61 to 75 — with the middle square given free. Press Again for another card, and note the seed if you are printing a set, because the same seed always gives the same card and that is how you avoid handing out two identical ones by accident.

Frequently asked questions
Why does each column use a different range?
That is what makes 75-ball bingo work. The B column only ever holds 1 to 15, the I column 16 to 30 and so on, which means the caller can say "B seven" and every player knows instantly which column to look in. Without the split you would have to scan the whole card for every ball.
