75-ball bingo is the standard format played across the United States and Canada. Each card is a 5×5 grid with 24 randomly filled numbers and a free center space — the columns labeled B, I, N, G, and O each draw from a fixed number range, keeping the game fair and balanced.
Numbers run from 1 to 75, with each column assigned its own range: B covers 1–15, I covers 16–30, N covers 31–45, G covers 46–60, and O covers 61–75. Players mark off numbers as they are called, racing to complete a pattern — a straight line, four corners, a T-shape, or a full blackout — and shout "Bingo!" to win.
It is the go-to format for school fundraisers, family game nights, church socials, senior center events, and classroom activities. If you have played bingo in the US, you have almost certainly played the 75-ball version.
