Bingo is a game of chance played with randomly drawn numbers which players match against numbers that have been pre-printed on 5x5 matrices. The matrices may be printed on paper, card stock or electronically represented and are referred to as cards. Many versions conclude the game when the first person achieves a specified pattern from the drawn numbers. The winner is usually required to call out the word "Bingo!", which alerts the other players and caller of a possible win. All wins are checked for accuracy before the win is officially confirmed at which time the prize is secured and a new game is begun. In this version of bingo, players compete against one another for the prize or jackpot.
