Randomly chosen numbers, usually up to 75 or 90, are called out by a banker.  The first player to achieve a card (or a line) in which all of the numbers have been called shouts bingo  or house  and collects the entire stake money, usually less a specified percentage, if that is permitted by local law.

Your cards / total cards in play = odds of winning.\n\n For example, if there are 100 bingo cards in play in a game and you take 10 cards, you have a 10 in 100, or a 10% chance of winning.
