The easiest way to get started is to play a public card. I made small ones for each category and a larger mixed card.

If you want to make your own, clicking on a preloaded theme in the Bingo Card Generator will load those prompts into the prompt box. Then scroll down to the card box to point and click on the features you want, like the size. When you click the button to make a card, its code will appear in a box further down that you can copy and paste into your blog.
