Bingo cars are used to play various bingo games, including U.S. style bingo and UK style Housie. Cards are usually made of cardboard or non-reusable paper, but more and more bingo halls are beginning to use computerized cards. Bingo cards are printed in various styles (see below) with randomized bingo numbers. As bingo numbers are called, players either check off the boxes with a pen or marker, or use a bingo daber/dauber to stamp the box.
