The 75-ball game uses a 5×5 card with B-I-N-G-O columns (B from 1 to 15, I from 16 to 30, and so on) and a free space: 24 numbers per card. It is the standard format in the United States. The 90-ball game uses a 3×9 ticket with 15 numbers, 5 on each row, and is sold in strips of 6 tickets that together cover all 90 numbers. It is played in stages: one line, two lines and full house.
