CASINO BINGO

 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.

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. In addition, double-action cards have two numbers in each square. Each space in the grid contains a number, except there may be one or more Free spaces, which are considered filled. Typically the game is played utilizing 75 numbers. The letters B, I, N, G, O are pre-printed above the five vertical columns, with one letter appearing above each column. The center space may be marked "Free". The printed numbers on the card commonly correspond to the following arrangement: 1 to 15 in the B column; 16 to 30 in the I column; 31 to 45 in the N column; 46 to 60 in the G column and 61 to 75 in the O column, but in some cases, there can be the numbers (1-75) in any of the columns. 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.

There are about 5.52*10²⁶, (exactly 15⁵ × 14⁵ × 13⁵ × 12⁵ × 11⁴, or 552,446,474,061,128,648,601,600,000) possible arrangements of the numbers on a bingo card.

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.

The numbers which are called in a game of bingo may be drawn utilizing a number of methods to randomly generating 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.

When someone only needs one number in order to complete the Bingo pattern, he/she is considered to be Ready, Waiting, Cased, Set or 'has a chance'.

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.

False Alarm - Term used when one calls bingo but is mistaken. This could be because of mishearing the caller or stamping the wrong number by mistake. If one calls a falsie, they genuinely believe they have a bingo. Also known as a social error. Another term used for this is a bongo.

Crying Number(s) - Once a valid bingo has been claimed and the game is officially closed, the numbers that would have been drawn next are known as the crying numbers due to fact that any person who needed the next number would be crying.

Hard Way Bingo - A hard-way bingo is a bingo pattern in a straight line without the use of the free space
