Best UK Online Slot Game Providers

Gaming providers are what makes online casinos possible. The casinos themselves don’t produce any games. The games are leased, and therefore they’re the same at every casino. There are, however, big differences between the gaming providers. The gaming providers create different games with different features and in different styles. While they may look similar on the surface, there are vast differences “under the hood”. You can read more about these differences on our page dedicated to casino games and video slots because here we’ll focus on the providers of these wonderful games.

We’ll tell you all about the gaming providers and their gaming platforms and their differences. Who are offering jackpot games, and where live casinos come from. If you know which provider you’d like to know more about, just skip ahead and find the provider in the list below. You’ll find all the gaming providers for UK casinos, such as NetEnt, Microgaming, Playtech, Evolution, Play’N GO, and many more.

                        There are few names in the online casino industry that are well known for providing some truly high-quality games. When it comes to live casino games for online casinos, Evolution Gaming is truly outstanding. There are about a handful of other game providers of live casino games, too, such as NetEnt and Microgaming, but Evolution is the market leader.

                        When it comes to video slots it’s more difficult to say who the best provider is. There are about a dozen top slot providers who could claim the spot at any given moment. Our personal favourites at the Mr. Gamble office are the ones listed above.

                        We love them for different reasons. NetEnt creates quality games for both live casinos and video slots. Microgaming is the undying classic. Yggdrasil is a fairly new company, but they’re innovative in their approach to slots.

                        Evolution is totally unbeatable with their live casino games, both in regards to quality and innovation. Play’N GO stuffs their games with extra features. Betsofts’ effort to gamify their video slots is amazingly innovative. iSoftBet has a gamification tool that’s excellent for mobile slots. Playtechs’ branded slots are one-of-a-kind… We like them for different reasons.

                        With that said, the other gaming providers do have their own benefits. There are still new ones being launched on a fairly regular basis with their own niches and charm. So read up on the slot game providers to find your own personal favourites.

                        Online Casino Providers of Casino Games

                        UK Online casino game providers

                        There are many different types of online casino games. “Video” is a broad term to cover all non-live casino games. Video Poker and Video Slots are the simplest explanations for this. It’s the difference between mechanized poker games and slots.

                        In the realm of live casino games, there’s been a revolutionary evolution with Evolution Gaming on the frontline. Blackjack, Roulette, Poker and other classical table games in all sorts of variation are no longer the only options. Board games and TV-shows have been formatted into live casino games. The board game Monopoly is available at live casinos. The TV show Deal or No Deal too.

                        The casinos games have really evolved from the good old fashioned “one-armed bandits” and dice games. 

                        What are the best online casino games?

                        The best online casino game depends completely on your own preference. Many players only like live casino games while others stick to video slots. Some enjoy the thrill of chasing a progressive mega jackpot, others enjoy lotteries. There’s something for everyone.

                        Online Slots

                        Mega Fortune is one of the greatest jackpot games of all time. Luxurious symbols such as champagne glasses, limousines, and diamond rings, create a fancy and enjoyable online casino experience! It’s also one of the highest paying slots of all time.

                        Video Slots

                        Another hugely popular video slot is Mega Moolah. Together with Mega Fortune, it’s the highest jackpot ever won at an online casino.

                        A slot that hasn’t quite received the attention it probably should is Max Quest: Wrath of Ra. The gamification of this game is something truly new. Many online casino providers are still stuck in the old ways of thinking. 5 wheels and 3 lines with no extra features “spin-n-win” doesn’t quite cut it anymore. Sure, the concept still has its charm, but it doesn’t entertain for hours.

                        Online Casinos UK and Game Platforms

                        Online casinos make agreements with slot providers. A single casino is free to make agreements with as many online casino providers as they want. That’s why we’re of the belief that, the more slot providers at a casino the better the casino is. 

                        When making an agreement with a provider, the casino gets access to the gaming providers platform. Via the platform, casinos get a wide selection of the best and most popular games from said provider.

                        Not all game platforms are compatible with all online casinos. That’s why it’s important for the casino to be built to be flexible and adaptable in order to be able to tie several different platforms to their system, and thus be able to offer more casino games.

                        Why does the game platform matter so much for UK Players?

                        There are many game platforms available. For example, Microgaming’s Quickfire makes it easier for the company to release new games. At the same time it helps online casinos to get some great Microgaming games to their offerings.

                        Other game providers can also use the Quickfire game platform. With a Microgaming license, slots providers have access to the Quickfire platform and can release their own games there. To mention a few game platforms we can tell you that Quickspin, Genesis Gaming, and Rabcat are working this way.

                        The game platform is very important for an online casino. It’s how they offer a wide range of games to their customers without the need of purchasing licenses for all the different games.

                        Another popular platform used by many is NYX Gaming. NYX has its own provider as well, which is NextGen Gaming. The NYX Gaming platform mostly consists of its own games, but there are some games included from other slot game providers as well.

                        Jackpot Game Providers

                        Jackpot slots and games with Progressive Mega Jackpot are very popular nowadays. A progressive jackpot means that the jackpot sum grows every single bet placed on the slot. This comes in 2 variations - Network Jackpots and single Casino jackpots.

                        If it’s a single casino mega jackpot, then it’s only the bets made on the jackpot game on that particular casino that contribute to the progressive jackpot growth. If it’s a network jackpot, then all casinos within the game platforms network will contribute to the growth of the progressive jackpot.

                        An example is Microgaming’s Mega Moolah. It’s one of the most popular progressive mega jackpot slots. Mega Moolah is the Guiness World Record holder of the largest jackpot for online casino games. In 2016 the Mega Moolah jackpot paid out close to €20 million. This is a prime example of a network jackpot. NetEnt has also served some massive jackpot wins throughout the years. 

                        Microgaming and NetEnt are the two biggest online casino providers offering jackpots, but there are some smaller jackpot game providers on the market as well. For example, Betsoft’s Glam Life slot offers jackpots up to several millions of euros, same as Yggdrasil’s Mega Joker.
