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.
Alternative methods of play try to increase participation by creating excitement. Since its invention in 1929, modern bingo has evolved into multiple variations, with each jurisdiction's gambling laws regulating how the game is played. There are also nearly unlimited patterns that may be specified for play. Some games require only one number to be matched, while cover-all games award the jackpot for covering an entire card. There are even games that award prizes to players for matching no numbers or achieving no pattern. See "Variations" for more details.
The most common Bingo cards are flat pieces of cardboard or disposable paper which contain 25 squares arranged in five vertical columns and five horizontal rows. Each space in the grid contains a number.
A typical Bingo game utilizes the numbers 1 through 75. The five columns of the card are labeled 'B', 'I', 'N', 'G', and 'O' from left to right. The center space is usually marked "Free" or "Free Space", and is considered automatically filled. The range of printed numbers that can appear on the card is normally restricted by column, with the 'B' column only containing numbers between 1 and 15 inclusive, the 'I' column containing only 16 through 30, 'N' containing 31 through 45, 'G' containing 46 through 60, and 'O' containing 61 through 75.
The number of all possible Bingo cards with these standard features is P(15,5) × P(15,5) × P(15,4) × P(15,5) × P(15,5) = 552,446,474,061,128,648,601,600,000 or approximately 5.52×1026.
In U-Pick'Em bingo and other variants of bingo, players are issued three 25 number cards which contain all 75 numbers that may be drawn. Players then mark which numbers they wish to play and then daub those numbers according to the numbers drawn. In addition, double-action cards have two numbers in each square.
A player wins by completing a row, column, or diagonal. The most chips one can place on a Bingo board without having a Bingo is 19, not counting the free space. In order for this to happen, only one empty cell can reside in each row and each column, and at least one empty cell must be in each diagonal, for instance:
B I N G O
● ● ● ●
● ● ● ●
● ● □ ●
● ● ● ●
● ● ● ●
In addition to a straight line, other patterns may be considered as a valid bingo in special games. For example, in the illustration above, the 2x2 square of marked squares in the upper-right-hand corner would be considered a "postage stamp". Another common special game requires players to cover the four corners. There are several other patterns, such as a Roving 'L', which requires players to cover all B's and top or bottom row or all O's and top or bottom row. Another common pattern is a blackout, covering all 24 numbers and the free space.
The numbers that are called in a game of bingo may be drawn utilizing a variety of methods to randomly generate the ball call. With the expansion of computer technology in bingo, electronic random number generators are now common place in most jurisdictions. However, some jurisdictions require mechanical ball draws which may utilize a randomly shuffled deck of bingo calling cards, a mechanical ball blower that mixes ping pong balls with blown air or a cage which is turned to mix small wooden balls. All methods essentially generate a random string of numbers by which players match to their bingo cards.
Single games often have multiple bingos; for example, the players first plays for a single line; after that, play goes on until a full card is called; then, play continues for a consolation full card.
Players often play multiple cards for each game; 30 is not an unusual number. Because of the large numbers of cards played by each player, most halls have the players sit at tables to which they often fasten their cards with adhesive tape. To mark cards faster the players usually use special markers called daubers. At commercial halls, after calling the number the caller then displays the next number on a television monitor; bingo cannot be called until that number is called aloud, however.
Bingo is often used as an instructional tool in American schools and in teaching English as a foreign language in many countries. Typically, the numbers are replaced with beginning reader words, pictures, or unsolved math problems.
Ready/Waiting/Cased/Set/Down/Chance – When someone only needs one number in order to complete the Bingo pattern, he/she is considered to be Ready, Waiting, Cased, Set, Down or 'has a chance'.
Breaking the Bubble or "Possible" – The bubble is the minimum number of balls required to complete the Bingo pattern. This is the earliest point any player could have a valid bingo. Example: Winning pattern is 1 hard way bingo, a straight line without the free space. The minimum number of called numbers is 5 although it is not considered Breaking the Bubble or possible until 1 number in each column or 5 numbers in a single column have been called.
Jumping the Gun – One who calls bingo before having a valid bingo. The most common situation is someone calling bingo using the next number in the screen before it has been called.
Wild numbers – Many bingo halls will have certain games with a wild number. Wild numbers allow bingo players to start with multiple called numbers. Typically the first ball drawn is the determining factor.
Standard – All numbers ending with the second digit of the first number. Example: First ball is 22. All numbers ending in a 2 including B2 is considered a called number.
Forwards/backwards – All numbers beginning or ending with the wild number. Example: First ball is 22. All numbers beginning or ending with a 2 is considered a called number. If the first ball ends with an 8, 9 or 0, another number may be drawn as there are no numbers starting with a 8 or 9 and only 9 numbers starting with a zero. Some halls will also redraw a number ending with a 7 as there are only six numbers beginning with a 7.
False Alarm or Just Practicing– Term used when one calls bingo but is mistaken. This could be because of mishearing the caller or stamping the wrong number by mistake. One who calls a "falsie" genuinely believes he/she has a bingo. This is also known as a "social error." Another term used for this is a "bongo."
Hard Way Bingo – A hard-way bingo is a bingo pattern in a straight line without the use of the free space.
The game of bingo can be traced back to a lottery game called "Il Giuoco del Lotto d'Italia" played in Italy in c.1530. By the eighteenth century, the game had matured, and in France, playing cards, tokens, the reading out of numbers had been added to the game. In the nineteenth century, Bingo was widely used in Germany for educational purposes to teach children spelling, animal names, and multiplication tables.
Le Lotto was then subsequently created by the French in 1778. This unique lotto variation featured 27 squares in a unique layout of three rows and nine columns. The numbers within the boxes ranged from 1 through 90. Only five squares within each row contained numbers which subsequently led to the design of modern day bingo.
Hugh J. Ward standardized the modern game at carnivals in and around the Pittsburgh and Western Pennsylvania areas in the early 1920s. He went on to copyright "Bingo" and author the rule book on it in 1933.
The game was further popularized when at a traveling carnival near Atlanta in December 1929, toy merchandiser Edwin Lowe noticed how engaged the players were of a Beano game using Ward's rules and dried beans, a rubber stamp, and cardboard sheets. Lowe took the idea with him to 1930's New York where he introduced the game to his friends. He conducted bingo games similar to the ones he had witnessed and Ward had standardized, using dried beans, a rubber numbering stamp and card board. His friends loved the game. One theory on the origin of the name is that one of his players made bingo history when he was so excited to have won that he yelled out “Bingo” instead of “Beano." However the word was used in Great Britain since the 1770s and had migrated to the Pittsburgh region at least a generation before Lowe's 1930's claim.
The Lowe produced Bingo Game had two versions; the first a 12-card set for $1.00, the second a $2.00 set with 24 cards. Bingo was a wild success. By the 1940s Bingo games were all over the country. Lowe had many competitors he requested that they pay $1.00 a year to conduct the games and to use the name Bingo.
In the US, the game is primarily staged by churches or charity organizations. Their legality and stakes vary by state regulation. In some states, bingo halls are rented out to sponsoring organizations, and such halls often run games almost every day. Church-run games, however, are normally weekly affairs held on the church premises. These games are usually played for modest stakes, although the final game of a session is frequently a coverall game that offers a larger jackpot prize for winning within a certain quantity of numbers called, and a progressive jackpot is one that may increase per session until it is won.
Commercial bingo games in the US are primarily offered by casinos (and then only in the state of Nevada), and by Native American bingo halls, which are often housed in the same location as Native American-run casinos. In Nevada, bingo is offered mainly by casinos that cater to local gamblers, and not the famous tourist resorts. They usually offer one-hour sessions, on the odd hours, i.e. 9am, 11am, 1pm etc. daily, typically from 9am thru 11pm; except Arizona Charlie's which has round the clock bingo, but still hour sessions, on the odd hour, with relatively modest stakes except for coverall jackpots. Station Casinos, a chain of locals-oriented casinos in Las Vegas, offers a special game each session, called "Jumbo" that ties all of its properties together with a large progressive jackpot. Most Bingo parlors in Las Vegas use hand held machines on which the games are played, except the station casino, the Fiesta Casino which has paper bingo cards and no machines. Native American games are typically offered for only one or two sessions a day, and are often played for higher stakes than charity games in order to draw players from distant places. Some also offer a special progressive jackpot game that may tie together players from multiple bingo halls.
As well as bingo played in house, the larger commercial operators play some games linked by telephone across several, perhaps dozens, of their clubs. This increases the prize money, but greatly reduces the chance of winning due to the much greater number of players.
Bingo halls are sometimes linked together (as by Loto Quebec in Canada) in a network to provide alternative winning structures and bigger prizes.
Bingo is also the basis for online games sold through licensed lotteries. Tickets are sold as for other numbers games, and the players get receipts with their numbers arranged as on a regular bingo card. The daily or weekly draw is normally broadcast on television. These games offer higher prizes and are more difficult to win.
The bingo logic is frequently used on scratch card games. The numbers are pre-drawn for each card and hidden until the card is scratched. In lotteries with online networks the price is electronically confirmed to avoid fraud based on physical fixing.
In recent years bingo halls have seen a decline in attendance and revenue. In Ontario, revenue at charity bingos has declined from $250 million to $50 million in the past ten years alone. Reasons for this decline include the expansion of competing forms of entertainment, such as charity casinos, race tracks with slots, large commercial casinos, and even movie theatres. In order to compete in this competitive marketplace, bingo halls have turned to technology to stem the decline. Ontario alone has opened five eBingo centres which give players an option to play bingo on a computer, allowing them to play at their own pace. In addition, electronic bingo has managed to draw in a larger male audience. The bingo industry is now lobbying the Ontario government to expand the number of eBingo centres in hopes of seeing a rise in revenue and attendance at bingo halls.
Some gay bars and other LGBT-oriented organizations in both Canada and the United States also stage bingo events, commonly merged with a drag show and billed as "Drag Bingo" or "Drag Queen Bingo". "Drag Bingo" events were first launched in Seattle in the early 1990s as a fundraiser for local HIV/AIDS charities. They have since expanded to many other cities across North America, supporting a diverse range of charities.
A common form of bingo which allows players to mark the numbers they wish to monitor for a win. While this game closely resembles Keno, a game invented by the Chinese which predates the Han Dynasty, it is recognized as a variant of bingo and is permitted in almost all jurisdictions.
A game where numbers are pre-drawn and players purchase sealed bingo cards which are then matched against the pre-drawn numbers. If a specified pattern is achieved, then the player usually wins a prize according to a prize table. Some versions are played until a player achieves a top level prize and then new numbers are drawn and the game begins anew. This type of bingo may be played over days, weeks or months depending on the difficulty of achieving a top level prize.
Typically 43 to 48 numbers are pre-drawn at the beginning of a bingo session. The numbers pre-drawn can be odd,even or the first 43 numbers that pop out the machine. Players purchase cards and mark out all even,odd or pre-drawn numbers. At a designated time, the caller asks if anyone has bingo. If no one does, the caller then draws one ball at a time until someone shout bingo. This game is sometimes played as a "progressive" game, where the jackpot increases if no one hits bingo before the desired amount of balls are called. If no one has achieved bingo before or on the desired ball count then the game is played again in another session in which the desired ball count increases by one and the jackpot is increased also. The player who hits bingo after the desired ball count does not win the jackpot but does win a consolation prize. If a player does hit bingo in the right amount of numbers then they win all the money in the jackpot. The ball count goes back to 43 after the jackpot is won and the ball count increases by one until the jackpot is won again.
Bingo on Facebook differs from traditional online or land based bingo games. Most games feature 'power-ups' which give individual players an advantage on winning the game when using such power-ups. Players can also collect, buy and share virtual items with friends on the Facebook platform. This adds to the community element which is otherwise not experience in other forms of online and land based bingo. Some great examples of Facebook bingo games are Bingo Bash, BamBam Bingo, Bingo Blitz and Bingo Island.
Up to 15 players are randomly issued a number from 1 to 15 which corresponds with the top row of the bingo flashboard. Numbers are then drawn and the first person to have all five numbers in their column be drawn wins. This is a fast paced and exciting form of bingo typically played in fraternal organizations.
With the expansion of Tribal gaming across the US, there are numerous versions of bingo which now emulate the fast action of casino like table games but utilize the principals of bingo where players mark and monitor matrices cards with chips. Casino games like Roulette, Acey Duecy and Money Wheel have bingo counterparts which are permitted to be played under bingo licenses in many parts of the country.
The advent of computer technology in bingo has blurred the lines between traditional slot machines and bingo slot machines. To the average person, bingo-based slot machines are physically indistinguishable from an RNG based slot machine typically seen in Atlantic City or Las Vegas. These devices are commonly called Class II machines, because the federal Indian Gaming Regulatory Act separated bingo, including electronic and mechanical aids, where players play against each other, from Class III slot machines, where player play against the house.
An inverted game where a player that gets a bingo is eliminated and knocked out of the game. The winner is the player who fills out the most spaces on their board before getting a bingo.
Themed variants of the traditional game include drag queen bingo, punk rock bingo, and beach blanket bingo.
