| The card in 75-ball Bingo is familiar to all. There are 5 columns and 5 rows.
The letters B-I-N-G-O head the columns in order. The center square is the Free
Place. So, there are 24 numbers on a 75-ball card. You might think that there
aren't so many possible cards using this configuration. There are, in fact,
several hundred million different card faces for 75-ball. Anyone who buys
multiple cards for 75-ball can be sure to find cards that have no numbers in
common. Finding diverse cards is a big strategy in Bingo because once all the
players have selected their cards, have gotten set up at a table, and the caller
is ready to start the evening's entertainment, luck pretty much takes over.
