How it works
Standard 75-ball layout: B holds 1-15, I holds 16-30, N holds 31-45, G holds 46-60 and O holds 61-75, with the centre square free. Each column is drawn without replacement, so no number appears twice on a card.
The formula
Five independent draws without replacement, one per column, from that column's 15-number block.Bingo Card Generator: common questions
