Below is a typical bingo card layout showing an example of the various numbers under each letter. The letter B will have numbers from 1 through 15, the letter I will have numbers from 16 through 30, the letter N will have numbers from 31 through 45, the letter G will have numbers from 46 through 60 and the letter O will have numbers from 61 through 75 in that column.
A caller will usually refer to both the number and the letter when specifying which games come up, for example – N35, G50 and so forth.
As can be seen from the diagram above, a bingo card has a total of 24 numbers, with the middle number being a blank space. Numbers allocated on the cards are random and are never the same in a game.
