What Every Bingo Card Contains
A standard 75-ball bingo card is a 5x5 grid with the letters B-I-N-G-O heading each column. Each column holds a specific number range: B covers 1-15, I covers 16-30, N covers 31-45, G covers 46-60, and O covers 61-75. The centre square is a free space, already marked at the start. In our 90-ball rooms, cards shift to a 9x3 layout —
nine columns, three rows, with fifteen numbers spread across each card and blank spaces filling the rest. Numbers are called randomly, and you mark each one as it appears. The win condition depends on which pattern the current session targets — a single line, two lines or a full house.
