There are many factors that contribute to the odds of winning bingo. The game is played with balls drawn from a drum, and the numbers that are drawn determine the numbers that will be called out by the caller.
The game is played with either 52 or 75 balls, and each player has six numbers (1-5) and a bonus number (6). The bonus number can be either a number that is not called out during the game, or a number that is called out twice.
The odds of winning bingo depend on how often your numbers are called out. If your number is called out only once, your odds of winning are about 1 in 15. If your number is called out twice, your odds of winning are 1 in 6. If your number is called out three times, your odds of winning are 1 in 3.
If your number is called out four times, your odds of winning are 1 in 2.5. If your number is called out five times, your odds of winning are about 1 in 2.
