What Every Bingo Card Section Means
A standard bingo card uses a 5x5 grid with five columns labelled B, I, N, G, and O. Each column holds a set range of numbers — B runs 1 to 15, I runs 16 to 30, N runs 31 to 45, G runs 46 to 60, and O runs 61 to 75. The center square is a free space, already marked
before the round begins. Numbers are randomly pre-assigned to each card, so no two cards in the same room are identical. When a number is called, you mark it — or let the auto-daub feature do it for you. Winning depends on completing a declared pattern before anyone else in the room does.
