All reputable online casinos and bingo sites use something called a random number generator to deal their cards and pick their bingo balls. This is a computational device that uses special software to ensure that cards and bingo balls are drawn completely at random, making for a fair online gaming experience for all players.

For online gaming sites, computer programmers have developed a wide range of computer programmes that pick random series of numbers in various ways. The variation between the computer programmes results in numbers being drawn truly at random, and following no discernible pattern. This makes it far harder for anyone to cheat in online games, and makes for a fairer game.

Computers have revolutionised random numbers. Just as in traditional casinos and bingo halls, cards and bingo balls are drawn at random by hand through shuffling and so on, before computers came along, mathematicians would work out formula by hand to develop random numbers on paper, which they then published as random number tables.

Online bingo sites and online casinos are free to choose their own programme for drawing random numbers, or may choose to use one than more varying programme for guaranteed sustained random number results.

Almost all random number generators use mathematical algorithms programmed into computers to draw their random number series. The numbers should never repeat, but it is possible that a number may be repeated eventually depending on the type of programme and algorithm that is being used by the site.

As well as being used in online bingo games and online poker games, random number generators are also used in casino games like blackjack, and roulette, as well as in computer simulations and anywhere where a random result is required. Some security applications use a form of random number generator too.

When choosing your online casino or online bingo site, make sure that they use a random number generator in their games. This ensures that you have a fairer online gaming experience. Look to larger, more established sites like 32 Red, who have been using random number generators in their bingo games since they first launched.
