90 Ball Bingo, or “Housie” in the United Kingdom, is becoming one of the world’s most popular online bingo games. It’s the official favorite leisure activity of young women between the ages of 20 to 25 years of age in the U.K., and has officially reached “craze” levels since its introduction in 2005.

You can join the craze by joining any one of the online bingo halls that we’ve recommended above. We’ve meticulously researched each of these bingo halls, and they’ve passed our rigorous tests of reputation, integrity and pure, unadulterated joy.

One of the great things about 90 Ball Bingo is that each game offers multiple prizes for each pattern. For example, 90 Ball Bingo has a prize for one horizontal line, and another prize for two horizontal lines. The biggest prize is reserved for the full house – i.e. all of the numbers on your bingo card.

So how do you play 90 Ball Bingo? The game starts with players buying their bingo cards, which consists of numbers spread out across three rows. On each of the rows, five of the nine spaces have numbers on them, while four of the spaces are blank, and numbers range from 1 to 90. The first column contains numbers from one to 10, the 2nd has numbers from 11 to 20, the 3rd has 21 to 30, and so on until the last, ninth column. The dealer begins by drawing numbers randomly from a container, calling the numbers out as he / she goes, and players mark each number called if it appears on their cards. The first player who completes any of the three established patterns, either one line, two line or full house – shouts out “Bingo!” to indicate a win, which the dealer confirms. Once confirmed, a new game begins.

Despite having more numbers, 90 Ball Bingo actually simpler than 75 Ball Bingo, which has many more complicated patterns.
