History and Rules of Bingo Games (by Wikipedia)

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 (usually in a straight line) 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.

Bingo cards are flat pieces of cardboard or non-reusable paper which contain 25 squares arranged in five vertical columns and five horizontal rows; Dual dab, or "double-action" cards have two numbers in each square. Each space in the grid contains a number, except for the center square, which is considered filled. The highest number used is 75. 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 is marked "Free". The printed numbers on the card 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.

There are about 5.52*1026, (exactly 155 × 155 × 155 × 155 × 154) 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 online Bingo rules offer a chance to play this unique game without even leaving your home. According to Bingo game rules for playing online, the numbers are not drawn from a special container, instead they are called by the random number generator, and this machine is also used for shuffling the poker cards and in other online games. Another difference in bingo rules, which is a big plus, is that the online player has an opportunity to use the 'auto-daub' feature, that automatically daubes /checks the player card after each number is called. This decreases the chance of you missing the number
