Bingo is a game of numbers and chances and hence, the concepts of odds and probabilities are very much involved in it. Also, different variants of the game come with different rules, payouts, odds, probabilities, and statistics, which further affect the odds. Here is a detailed discussion on bingo statistics.
Basic Bingo Probabilities
The statistical probability of winning a game of bingo depends on a lot of factors. The first and the most important consideration is the number of cards. The more cards a player buys, the larger are his odds of winning. For instance, with 1 bingo card and 9 players around, a player's odds are 1 in 10 while with 11 bingo cards, his odds significantly increase to 10 in 20.
The odds of winning bingo are, on the other hand, inversely proportional to the number of players in the room. The higher the number of players, the more the number of cards one has to purchase in order to increase the odds. With fewer players, the odds of winning are automatically higher. There is a correlation of these odds to the number of balls called too. The more the call progresses, the higher are the odds in favor of the bingo player.
75-Ball Bingo Odds
The 75-ball bingo, also referred to as the American bingo, is the most popular variant out there. The 75-ball bingo ticket comes with a 5X5 grid comprising 5 columns. The word BINGO is displayed along the top of the card and each column of numbers is placed under each letter. So, B has 1 to 15, I has 16 to 30, and so on. There is a blank or free space located in exactly the middle of the card. As the numbers are being called, players mark off the numbers. Apart from the single lines, two lines, and coverall, several patterns are considered winning patterns in this particular bingo variant.
As for the odds of winning patterns in the 75-ball bingo, the chances of getting a single line or two lines are obviously higher than getting a coverall or full house. Coverall requires the player to mark off all the numbers on the card, usually within a predetermined number of calls. Coverall patterns are considered in the somewhat large and progressive jackpot games. However, statistically speaking, it takes 72.96 balls to get a coverall with a single ticket in the 75-ball bingo.
90-Ball Bingo Odds
The 90-ball bingo is the British bingo and it is widely played all over Europe. The 90-ball bingo ticket has 3 rows and 9 columns consisting of 15 numbers. Each line of the 9 boxes has 5 numbers and 4 blank spaces. Accordingly, numbers 1-9 fall in the 1st column, 10-19 in the 2nd column, 20-29 in the 3rd column, and so on. The 90-ball bingo is played on a single strip consisting of a total of 6 tickets to be used in each round.
Unlike the 75-ball bingo, the 90-ball bingo offers just three ways of winning for the player. These are completing a single line, double line, and full house, which imply marking off all the 15 numbers on the ticket. The probability of completing a single row starts right at the 5th call of the number while the odds of getting even a full house are at the highest after the 50th call. The more tickets a player has, the higher are his chances of winning.
80-Ball Bingo Odds
The 80-ball bingo is a faster bingo variant that has been popularized by online bingo sites. The 80-ball bingo card has a 4X4 grid comprising a total of 16 numbers. Each of the columns comes with a different color and 20 numbers. So, the red column has numbers 1 through 20, yellow has 21-40, blue has 41-59 and silver has 60-80. As the numbers are called, players mark off the same on their respective cards. The most common winning patterns are single lines in any of the diagonal, horizontal, and vertical lines, four corners, and full house.
The probabilities of getting a coverall in the 80-ball bingo are 10,000 on the 35th ball draw, 1200 on the 45th ball draw, and 55 on the 55th ball draw. The same for a Frame pattern is 1000 on the 35th ball draw, 400 on the 45th ball draw, and 5 on the 55th ball draw. As in all the bingo variants, completing a single line or two lines is faster and easier for the player than getting a coverall.
30-Ball Bingo Odds
The 30-ball bingo is a newer and much faster version of the bingo. It is extremely popular online and is also referred to as speed bingo. The 30-ball bingo ticket comes with a small grid comprising just 9 numbers, randomly from 1-30. This particular variant is extremely simple and easy to play and most sites provide players with just one way of winning and that is, covering the full house by marking off the 9 numbers on the card. Many rounds of the 30-ball bingo can be played, which is also the reason behind its popularity.
The probability of getting a coverall in the 30-ball bingo is 0.011740 on the 20th ball draw while the same is 0.034767on on the 22nd ball draw and 0.091388 on the 24th ball draw.
So, the overall odds and probabilities of winning in a game of bingo depend on multiple factors as also the particular variant of the game being played, and how you play the game.
