There can be two winners in bingo, depending on how the game is played. If the game is played with a traditional bingo card, each player gets one chance to hit the ball and cover the numbers indicated. If the player gets at least one number in a column and at least one number in a row, they win that row or column of numbers. The second winner is whoever covers all of the numbers in a particular column or row.
The game can also be played with a bonus ball, which is a small ball that is added to the regular bingo balls. When this happens, players get three chances to hit the ball and cover as many numbers as possible. If they get at least one number in a column and at least one number in a row, they win that row or column of numbers. The third winner is whoever covers all of the numbers on the bonus ball.
