Hard Card

A hard card is a Bingo card that is printed on heavy material, such as cardboard, and has flaps or shutters that cover each number as it is called out by the Bingo caller. These types of cards with BINGO spelled out on the top and numbers under each letter typically have the following numbers under each letter: B: Five numbers between one and 15 picked randomly. I: Five numbers between 16 and 30. N: Four numbers between 31 and 45 and the free space. G: Five numbers between 46 and 60. O: Five numbers between 61 and 75. Cards are often produced using a series; some series have 6000 unduplicated cards while some series have 9000 unduplicated cards.
