A bingo card printed on heavy cardboard material usually with shutters to cover each number as it is called. A bingo card contains 24 numbered spaces and one "free space." The numbers are arranged in five rows or columns of five numbers each. The numbers in the "B" row contain five numbers between 1 and 15, picked at random. The numbers in the "I" row contain five numbers between 16 and 30. The numbers in the "N" row contain four numbers between 31 and 45 and the "free space." The numbers in the "G" row contain five numbers between 46 and 60. The numbers in the "O" row contain five numbers between 61 and 75. Players have thousands of unduplicated cards to pick from. Some manufacturers print unduplicated series of 6,000 cards. There are also series of 9,000 cards available. Hard cards and "flimsy" cards have a series number printed on them. Card number 1252, for example, will always have the same numbers in the same spaces. Hard cards are fast becoming a thing of the past. Soon they may even be collector's items!
