First time users might not think that the software at an online casino matters much but anyone who's played before will know it's a big deal.
Gone are the days where only two or three companies ruled the software landscape as the games of many creators can now be found.
In download casinos the games that you find are all provided by the same software supplier. For example, Betfair's download casino only offers Playtech games. In contrast, a recent trend is for casinos to offer instant games on their website from multiple software providers which allow them to get big name games that they wouldn't have had otherwise. Some have games from as many as 15 different software companies creating a much greater variety.
In this section we cover the software providers that you're most likely to find in the casinos listed on Jackpot.co.uk.
Microgaming is a South African online casino software developer and considered to be the most established in the industry.
They first started developing in 1994 and have long running relationships with some of the most renowned brands such as 32Red and Spin Palace. They're so big that at one stage it was estimated that 35% of online casinos were powered by Microgaming casino software.
Playtech was founded by billionaire playboy Teddy Sagi and launched its first games in 2001.
Since then Playtech software has gone from strength to strength and now includes multi-player games, large progressive jackpots, stunning casino game graphics and impressive live dealer games.

Amaya Gaming Group is a publicly traded company on the Toronto Stock Exchange. In 2012, Amaya acquired Cryptologic, who remain a separate entity when it comes to day to day operations.
Amaya has gained a large number of loyal followers. Most of these followers are interested in slots which have been the focus of Amaya's innovations. Unfortunately, they can't always play them as not that many casinos offer their games.
One of the company's most high profile partners is InterCasino, where the full range of Amaya games can be found. Historically its casino software wasn't as technically advanced or feature-packed as others providers but they're licensing deals mean that they had some of the most exciting titles around.
Net Entertainment is a Scandinavian firm that developed from an offline casino operator, and started providing online games in 1996.
With a firm commitment to making their titles the very best they can be, this is where to come looking for graphics, sounds and gameplay that you would not be able to get elsewhere - and plenty of old favourites too.
Consistently award-winning, regularly groundbreaking, and frequently among the more entertaining casino software providers - as the name suggests - NetEnt have been at the top of their game for two decades and show no signs of slowing up anytime soon.
