Explore the Standard Bingo Card Layout
A standard bingo card carries 25 squares arranged in a 5-by-5 grid, with each column labelled under one of five letters: B, I, N, G, O. The centre square is a free space — it counts toward any pattern without needing a called number. In Pinoy Bingo 90, the card format shifts to a 9-column layout with 90 balls, so the winning
conditions differ from the classic 75-ball game. Numbers in each column fall within a fixed range: B holds 1 to 15, I holds 16 to 30, and so on. Each card is randomly generated, so no two cards in a room are identical. Pattern rules — whether the room accepts a straight line, a full house, or a diagonal — are posted
in the room header before the game starts.
