Bingo is a game of chance in which randomly selected numbers are drawn and players match those numbers to those appearing on 5x5 matrices which are printed or electronically represented and are known as "cards." The first person to have a card where the drawn numbers form a specified pattern is the winner and calls out the word "Bingo!" to alert others and inform the caller of the win. The card must first be properly checked for accuracy before the "win" is officially confirmed at which time the prize is secured and a new game is begun.
Description of the game
Each bingo player is given a card marked with a grid containing a unique combination of numbers. The winning pattern to be formed on the card is announced. On each turn, a non-player known as the caller randomly selects a numbered ball from a container and announces the number to all the players. The ball is then set aside so that it cannot be chosen again. Each player searches his card for the called number, and if he finds it, marks it. The element of skill in the game is the ability to search one's card for the called number in the short time before the next number is called.
The caller continues to select and announce numbers until the first player forms the agreed pattern (one line, two lines, full house) on their card and shouts out the name of the pattern or bingo. One of the most common patterns, called full card, blackout and cover-all simply consists of marking all the numbers on the card. Other common patterns are single line, two lines, the four corners, centre cross, L, T, Y, postage stamp (2x2 and in a corner) inner square (4 × 4), roving square (3 × 3), and roving kite (a 3 × 3 diamond). Lines can be made horizontally, vertically, or diagonally. Inner and roving squares and kites must be completely filled; roving squares and kites may be made anywhere on the card.
Equipment
Most modern bingo halls have 1-2 bingo blowers and 1-2 flashboards. The blowers all have four features, a chamber to blow the balls from, a tube to permit 1 ball at a time, a master board, and a way to return the balls from the board to the chamber. Most modern blowers have a simple computer, that can be programmed to display certain games, in a certain order, called a session. Some new blowers run off standard household computers, and have their own GUI or Graphical User Interface, to operate the blower.
Culture
Games often have multiple bingos — for example, the players may first play for a single line, then after that is called continue playing for a full card, then for a consolation full card.
Players often play multiple cards for each game; thirty 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 primary schools and in teaching English as a foreign language in many countries. Typically, the numbers are replaced with beginning reader words (such as those drawn from the Dolch word lists), pictures, or unsolved math problems. Recently[when?] many teachers have taken to using software to automate the creation of bingo cards, as it is slow and laborious to do it by hand for large numbers of cards.
A system of etiquette exists in organized play. It is considered rude to carry on conversations with others or on cell phones during an active game. Making excess noises with daubers or allowing your cell phone to ring is also considered rude.
Terminology
Being Ready – When someone only needs one number in order to complete the Bingo pattern, he/she is considered to “be ready”.
Breaking the Bubble – The bubble is the minimum number of balls required to complete the Bingo pattern. This is the earliest point anyone 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” 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 5 numbers beginning with a 7.
