The patterns are declared and explained by the caller before the bingo game starts and are displayed on an overhead screen. A game can have two patterns. One player may win both the patterns or there may be one winner for each pattern.
Some popular patterns and how to understand them are given below.
The straight pattern is used in one line, two line or three line bingo cards. The line containing five numbers can be diagonal, vertical or horizontal in one line bingo. It can be in any direction in two or three line bingos.
The pattern T is shown upright whereas a crazy T pattern can be upside down, slanted or sideways.
Two lines in parallel make up a pattern similar to the two tracks of a railway line in double or triple bingo.
Two diagonal starting at opposite corners and a central vertical line make up the Asterisk pattern. Adding a horizontal line through the middle forms the Starburst pattern. The Bow Tie pattern is made up of the diagonal lines connected by two vertical lines at each edge.
Straight lines are used to make patterns look like alphabets both normal and crazy ones with their upside down, reverse and sideways formations.
A horizontal line in the topmost row connected to a diagonal line starting at the top rightmost corner makes up the 7 pattern.
A coverall or blackout pattern consists of all the numbers on a card getting marked within a fixed number of calls in a progressive game. If progressive jackpots are not allowed, then the game is carried on without any restrictions on the number of calls.
The odd-even pattern is made up of all the odd numbers or all the even numbers of a card.
Speedball pattern is the same as coverall pattern with only the speed of the caller being very fast by omitting the letters of the numbered balls.
All the spaces along the edges of the card makes up the pattern called the outside picture frame. The inside frame pattern is formed by squares surrounding an empty square in the middle.
The little diamond pattern is made up of four squares with an empty square at the centre. The big diamond is made up of eight squares with five empty squares in the centre.
A Single Postage Stamp pattern is made up of four adjacent squares at the corner of the card. Double or Triple Postage Stamp patterns are two or three corners of the card. A postage stamp pattern with four corners is called a Clover Leaf pattern
Just like the postage stamp pattern which has two adjacent rows with two squares each, the Six Pack pattern has two adjacent rows with three squares in each row and the Block of Eight pattern has four squares in adjacent two rows.
The kite or magic wand pattern is made up of four adjacent squares in one corner of the card with a diagonal line across the card. A crazy kite pattern is upside down with the tail pointing towards any one corner. The arrow pattern is a six square triangle.
The pattern looking like the American flag consists of all squares on the three top rows with two vertical squares as flag poles on either the left or the rightmost edge of the card. The castle pattern has all squares on the bottom two rows and a vertical line in the centre column.
A zigzag line made up of five squares starting at column B, represents the snake pattern. A crazy snake pattern can start at any of the other corners of a bingo card.
