It is quite simple to understand the rules of bingo. Using a contraption like that of a lottery ball holder, the numbers 1 to 75 are picked by a caller. The caller then displays the number on the screen and announces the number. You will be allotted a particular number of seconds to locate the number on your bingo cards. Modern bingo cards are really pieces of paper each containing three, six, or nine cards. Each card contains randomly selected numbers.
The "B" column contains numbers 1 to 15, the "I" column has the numbers 16 - 30, the column for "N" has numbers 31 - 45 (the middle of the column contains the space for FREE), while the numbers 46 - 59 belongs to the "G" column. The "O" column completes the 75 numbers. When your card contains the called number, mark it out with your dabber (a plastic bottle containing ink, covered with a dabbing sponge). When you are the first to complete the numbers based on the desired pattern in accordance to the rules of the specific game, you shout "Bingo!" as loud as you can until you are heard by the caller. You can now claim the money.
During the duration of the session, several variations of bingo will be played. Aside from the regular games, the games will vary depending with the bingo hall. Regular games will have players fill their card with a straight-line pattern - horizontally, diagonally or vertically. Many regular games also play the "four corners" variation of bingo meaning you mark the numbers located at the top and bottom "B" and "O".
Other bingo halls may play other games, but here are the most common games being played:
Blood, Sweat, and Tears. One bingo card is filled with three bingos not counting the corners.
Six Pack. The card is marked in order to create a pattern consisting of six numbers - three numbers from two rows arranged horizontally or vertically. The use of the free space may be optional.
Nine pack. Nine numbers form a square.
Eight states. The free space is surrounded by numbers.
Postage stamps. A single card is filled with a couple of squares of four numbers, separately located in the corner of the bingo card.
Kite and Tail. A diagonal is formed with one of the corners passing through the diagonal to resemble a kite.
Top and bottom. The top and bottom rows are filled.
Dotted picture frame. Alternately mark the spaces around the card.
Cover all. Usually concludes the games for the session. All numbers on the card are marked for bingo.
Other possible games may still be played. Each game is explained by the caller. In addition, a written explanation of each game will be provided to assist you during the duration of the session.
