Bingo is won by filling bingo cards. The first player to fill a card in a specific way wins the game, and it is often easy to continue the game and thus allow many people to win, depending on how the game is organized. Depending on the rules and the variation of bingo being played, the way to fill the card may differ. In the classic versio of bingo a player needs to fill a row or a column to win, but in other versions it may be necessary to fill the entire card, only find a single correct value, or maybe fill a specific pre-determined pattern in the card.
