This is a staple bingo FAQ. There are two main categories of bingo games – the 90-ball version known as “housie” and the 75-ball version. 90-ball bingo: this version is mostly common in UK and Australian casinos, among other countries. The player’s ticket in housie has three rows of nine spaces. However, not all the spaces will have a number. The aim in 90-ball bingo is to completely fill one or more rows in order to win. 75-ball bingo: this version is the one most commonly played. It’s also the most popular bingo format. In 75-ball bingo, the game’s card has five columns of numbers with five rows each. Furthermore, the straight line is commonly the winning pattern.
