A typical bingo game utilizes the numbers 1 through 75. The five columns of the card are labeled 'B', 'I', 'N', 'G', and 'O' from left to right. The center space is usually marked "free" or "free space", and is considered automatically filled.
Please note that you will lose any right to claim that prize if you fail to have the playing of that game stopped before the caller has started to call the next number.
