The main types of linens to play any international bingo game are 90 and 75 numbered cards. If you have a choice play 90 numbered cards first. They are in a 5 by 5 square shape. The other game of the 75 numbers are called international bingo and they have a different shape and different numbers. They are in a square type. Then you have the cross game and the blackout game.

You will find that various bingo companies will produce different combinations of cards. The number of cards is usually in the range of 80 – 120. Some bingo games come with a double pack of cards in the same style. The other cards of the same series are called a full house and a gut shot.

There are other combinations of cards that are not normally considered to be bingo cards. They are called the printed cards. They have the same rules as the cards except for the fact that the numbers are visible. The majority of these cards will be a 4×4 square. The inside of the square is removed leaving a 4x4x4 hole. The inside of the square is also removed leaving a blank space. This is near the center of the card.
The outside of the cards should also be removed when they are not required for a certain game. The majority of the cards will be black and white. The B column will be black and the Start of the Game column will be white. Both of these cards should be marked accordingly.
The Chat column should be marked in a different way than other cards. The Chat card will act as a bookmark to remember who spoke what when. Full House cards should be drawn first when possible. If that’s not possible, the B column should be marked so it should not be covered and misalignment.
Full House Cards
The set of cards for the seventy-five numbers are all similar and are all used for the same purpose. They are essentially one large square with the four corners. Some of them have their own separate patterns, but the target square is always the same.
One of the patterns is the ” injected” pattern. It is a small square and a long straight. The injector square is usually covered by the “Make it!” square.
If you have ever played 75, 80, or 90, you will see a 75-square card in new decks. Unlike the other two card games, this card game will not let you fail. Once you learn and understand the rules, you will rarely fail.
One of the 75-square cards has the “Injected” pattern. Usually, it is the first card to be discarded in the center of the 75-square card. Ink is used to obscure the center square so players can’t see where the center square is, hence the name of the game.
If you see a card with the center square highlighted, that highlighted square can be removed to reveal the rest of the card. Again, the goal is to either spade up the center square or remove the highlighted square to reveal the rest of the card.
Of the 75-square cards, there are 25 squares that are not used in scoring and 25 squares that are used. Of the 25 squares that are not used, 25 squares are filled with bingo numbers. The 25 squares that are used are called “free” squares. They are not used to hold any bingo numbers.
The “free” squares are usually placed in the center of the 75-square playing card. This makes it easier to shuffle the cards when changing the order of the numbers. A “free” square can also be used to substitute for a different number, if needed.
The “Injected” pattern is a little harder to see. It is a square shape that measures 4 by 6. We also see this pattern because it is the third number drawn by the machine.
If you have ever played 75, 80, or 90, you should know that the “Injected” pattern is the square that is sometimes overlapped by the “free” squares. This sometimes makes a bingo number easier to mark because it makes aDirect Line.

Look for this pattern because it often can make a word, number, or symbol appear that is misspelled. Such as “60” to mark the card when it should be a BOGOF (buy one card only). Or “B51” to mark the card when it should be an Ace.
But, the BOGOF is also a great way to have a regular bingo player to mark their card when it should not.
Loose Bingo Cards
Loose Bingo cards make a card more interesting and give players more opportunities to use their creative “Injected” Bingo patterns. When playing bingo, it’s important to have a good time.
