The Biggest and Most Popular UK Casino Platforms - Last Updated April 2025
Casino games are the attraction that brings players to the site, but it’s not the casinos that create the games. The UK casino games are created by gaming providers, and the providers need to distribute their games. The distribution is done via dedicated platforms that support all sorts of functions that are needed to make it all come together.
So, who creates these platforms? The very first platform for UK online casino gaming serves as a great example of who the creators of casino platforms are.
Microgaming, one of the oldest gaming providers, launched operations in 1994. In 1995, Microgaming joined forces with a company called Cryptologic, which, at the time, was a reputable company in the security software solutions industry. Together, they launched the very first complete casino platform that supported instant deposits, tracking of player accounts with bonuses, and personal information in a virtual real-money environment.
Today, there is a vast number of casino platforms available. The platform acts as the core of any casino. However, not all of them are good, and most of them are (pardon the language) utter rubbish.
Why Trust Mr. Gamble?
For the safety of players and to keep operators accountable, the team at Mr. Gamble implements a world-class evaluation process for all online casinos. The team incorporates a strict due diligence process for listing casinos on Mr. Gamble by verifying the operating regions of casinos and the validity of local licenses, among other aspects such as customer service, game selection, banking methods, and bonuses.
Our editorial policy includes fact-checking all casino information while including real-world data to provide the most relevant and helpful guide for readers around the world. At Mr. Gamble, the players' safety and satisfaction are our top priority — you can rely on us to get the best possible offers from licensed online casinos.
There’s a clear top-list of the best casino platforms. Most of the best UK casinos online are hooked up to one or more of the following platforms.
Connect: Connect is created by one of the most prominent names in the industry, NetEnt. It’s a fully functional solution that provides casinos with RNG casino games (slots and table game machines), live casino games, support functions, instant payout casino solutions, business intelligence, and other services required to run a successful casino.
There are several gaming providers (game creators) connected to Connect. The more familiar providers include Red Tiger Gaming, Games Inc, and G (former Gluck Gamevy). More than 800 casinos online are hooked up to Connect, meaning that NetEnt slots are all over the shop.
Quickfire: Quickfire is one of the most used casino platforms in the industry. Created by infamous Microgaming, the platform offers a super simple solution for other gaming providers to connect to. Casinos get access to RNG casino games, live casino dealer games, a poker client, support functions, payment solutions and several other services.
About a dozen gaming providers on the Quickfire platform which is available at over 800 operators. Among the most famous providers on the platform are Quickspin, which is a huge name in the industry, but also smaller gaming studios like GameBurger and All41Studios and a dozen others.
One: Created by the British gaming giant Playtech, One is a complete platform for all kinds of gambling. Casinos connected to One has access to RNG casino games, live casino dealer games, sports betting and e-sports, bingo, poker, and so on and so on, the list is long. The list of games exceeds 600 titles, and the games are available at well over 700 online casinos.
CasinoEngine: The CasinoEngine platform is developed by Every Matrix. Unlike the other platforms on this list, Every Matrix isn’t a gaming provider but purely a casino platform for providers. They don’t create any of their own games, and that’s what makes them different from the competition. Casinos hooked up to the EveryMatrix casino platform, CasinoEngine, can access more than 11 000 casino games from over 175 gaming providers. The games are available at around 120 operators from all over the world.
Casino Platforms, a.k.a. Casino Software
As you probably understand by now, a casino platform, or casino software, is vital to all casinos, both established operators and new online casinos. It’s the framework that allows all casino action to be available to all players. Some other big and well-known platforms include:
- NextGen Gaming
- RabCat
- SkillOnNet
- White Hat Gaming
Even many small or independent online casinos rely on these platforms to deliver a full-featured gaming experience without building everything from scratch. By using established software, they can offer a wide selection of games, secure payments, and reliable player management while focusing on branding and customer engagement. This makes casino platforms a crucial foundation not just for major operators, but for newcomers and niche sites as well.
FAQ
What is a casino platform?
A casino platform is the fundamental framework that makes online casinos function. It’s a system to implement and manage online payments (deposits and withdrawals), tracking of player accounts, manage the selection of games, and everything else!
What’s the difference between casino platforms?
The differences between casino platforms are found in the details. Some platforms offer the services of far more payment options than other platforms. The same goes for all the aspects of a casino platform, some offer more options for one thing while others offer more options for another thing.
What are the most popular casino platforms?
Some leading casino platforms include SoftSwiss, Playtech, Microgaming Quickfire, and EveryMatrix, known for their extensive game libraries and reliable performance.
Which casino platform is the best?
It depends on what you’re looking for. NetEnt are well-known for offering tons of free spins in their games and free spins bonuses for their games, so “One” is perhaps the best platform for this purpose. The same goes for all the other aspects of casino software. But, in reality, you as a player shouldn’t focus too much on which platform is the best. You should rather focus on finding the best possible bonus for your type of play.
Can I get free spins on all casino platforms?
The short answer is yes. But, believe it or not, some casinos chose to not offer any free spins at all. So you’ve got to find the right casino with the platform you’re looking for. The easiest way to find it is to use your own choice of filters to the lists here on Mr. Gamble.
