75 Ball Bingo is a popular North American version of the classic 90 Ball game. Players purchase numbered bingo cards and then mark off the numbers that are called out at random. The winner is the first player to correctly complete a winning pattern. 75 ball bingo cards have 25 spaces, arranged in five vertical and five horizontal rows. Each of the 25 squares on the 75 ball bingo card (except for the center square) contains a number between 1 and 75. The center square is marked as a free space.
