Enter the bingo title, select the size of your bingo card grid, and type your items into the squares. Whatever items you enter into the squares will be shuffled around when the bingo cards are generated.

You can add numbers (like in traditional bingo), words, phrases, or pictures to your card. You can also customize the colors of the squares, and the bingo card itself.

Tip: You can put text and an image into a square. Use the text shadow to make the text "pop" against the background image. You can also change the vertical alignment of the text in the square so it does not cover the important parts of the image.

If your center square is the free space (and should not be shuffled around the card), make sure you check the "The center square is the free space" checkbox. Only 5x5 and 3x3 have a free space.

By default, when your cards are generated, the items are shuffled over the entire card. In traditional bingo, items are fixed to a certain column (and only shuffled within their respective column). To enable that, check the "Shuffle items only within their column" checkbox.

When you create your card, you can flip over a square to enter a clue/question. Whatever you enter on the back of your square will appear in the call list for your bingo game. For example, to help kids learn animal words, you might put the word "Bear" on the front of the square, and a picture of the bear on the back. When you play the game, the image of the bear will appear in the call list for your students to see. If they recognize the literal word "Bear" on their card, they would mark it.

You can use question/answer-style bingo to quiz players about anything!

A 5x5 bingo card can generate 15511210043330985984000000 unique cards. A 3x3 bingo card can produce only 362880 bingo cards. Cards are randomly generated, so the probability of getting a duplicate is infinitesimal on a 5x5 card.

After generating bingo cards or finding an existing bingo card, enter the number of cards you want to print, and select how many cards you want to print per page. You can print 1, 2 or 4 cards per page. Make sure you switch to landscape print mode on your printer to print 2 cards per page.

A call sheet is included with your bingo game. Simply read the items off in the order you see them. You can also print the call sheet, cut it out, and pull the items from a hat.

You should at least fill the entire bingo card grid. A traditional number bingo card has 75 items. You can add up to 350 squares to your card.

See the help page. But I strongly recommend you just play around. It's bingo. You won't break anything.
