A person believing they have the appropriate numbers covered on their bingo card, will call out "Bingo", loud enough for the caller to hear. The caller will pause the game and a floor walker will go to the player who called Bingo".
The floor walker will then verify that the game has been won, by comparing the numbers on the card to the called numbers. In some cases he will call out the numbers. In others he will call out a serial number on the bingo card sheet. The caller will punch the number into a computer and the computer will verify if the game has been won or not. If the game has not been won the caller will resume calling numbers until another person calls "Bingo" and the numbers are verified.
Once the numbers have been verified, prizes are awarded and another game begins.
