Explore How Bingo Cards Are Built and Played
A standard 75-ball bingo card is a 5x5 grid. Each column maps to one letter in B-I-N-G-O and holds numbers from a fixed range — the B column 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 centre square of the N column is always
a free space, already marked at the start of every game. When the caller draws a number, you mark the matching square on your card. Rooms in our lobby — including Bingo Harbor Room — may use 75-ball or 90-ball formats, so check the room label before you join. The 90-ball variant uses a 9x3 card with no free space.
