Top Slot Machine Providers 

If you visit any top online casino and head over to the games lobby, you’ll be faced with literally thousands of gaming possibilities. Many of these will be slots, though there will also be an array of more traditional table games, as well as live dealer offerings. Many gamblers make the assumption that it’s the online casino itself that develops and manufactures its own jackpot games. The truth is that the vast majority of online casinos are simply platforms on which game developers place their gambling products. And it’s not the casinos, but the slot machine providers themselves who provide the prizes.

So when it comes to casino games, the real question is not what are the best online casinos, but rather who are the best developers offering the most enjoyable games. Today at, we thought we take a look into the game providers who are presently offering the best slots. Of course, there are literally hundreds of providers based all over the world. However, some do stand head and shoulders above others.

When it comes to top developers from the UK, then Microgaming can hold its head high as it’s certainly one of the best. The company claims to have created the very first online casino and certainly offers some of the best video slots available across the internet today. The stable of slots games includes everything from 3D video slots to the old-fashioned classic retro 3 reel slot games.

RTG or Real Time Gaming used to be a big noise in the USA when it comes to online casino slot games. They were originally based in Atlanta, Georgia. But thanks to the Unlawful Internet Gambling and Enforcement Act, which was passed in 2006, they relocated offshore. Since that time, they have continued to produce an excellent roster of slots for all players who are looking to win the jackpot online. All these games feature top-notch graphics, and a selection of great prizes, including their generous progressive jackpots.

When it comes to game developers, then NetEnt is without a doubt, the best and most well-known brand coming out of Sweden. To say the company is large would be an understatement. After all, it’s listed on the Stockholm Stock Exchange. In 2020, NetEnt increased its overall reach by buying up the live gaming powerhouse, Evolution Gaming. This move made them one of the largest and most well-known slot machine providers on the internet. As you’d expect from one of iGaming’s leading players, they have a catalogue consisting of hundreds of top-level slots. Here you’ll find everything from retro fruit machines to exciting and immersive video slots. All of which offer a huge range of bonus features. As with most of the slots developers today, they also offer generous progressive jackpots which you can find in games like Hall of Gods.

These include such things as interactive maps, expanding symbols, bonuses, and of course, free spin bonus features. Once again, as with many of the sites featured on this list, Betsoft offers several progressive jackpot slots with eye-watering prizes for lucky winners.

The tiny country of Estonia has evolved into a high-tech hub for all sorts of internet-based industries.

Under their roof, you’ll find every gaming option possible. These include branded slots such as Gladiator, DC Comics, and Top Gun. So if you’re a fan of Superheroes or movies, then Playtech has you covered. All slot lovers can find the offerings from Playtech to be both exciting and immersive in both theme and gameplay.

Well before the online gaming revolution occurred, International Game Technology was one of the few casino game companies that had already placed a huge number of slots in many land-based casinos around the world. Thanks to this head start in the traditional slot space, IGT is now one of the largest gaming companies in the world. You can take your pick of almost any type of slot machine you can think of and the chances are, IGT will offer it. Today, IGT is taking a new direction with the Mega Jackpot series. These consist of a number of interlinked slot machines offering progressive jackpots that are worth millions of dollars. As such, they represent a great way to increase your jackpot winning chances.

Yggdrasil has been in business for just over 10 years and yet has already racked up a huge number of gaming awards. This is not surprising as the game’s producer and developer take pride in its production of visually stunning games with innovative features. A good example of this is the Gigablox feature, whereby blocks sized up to 6 X 6 can appear on the reels. Furthermore, many of their slots offer up to 200,000 ways to win, with the slots game Temple Stacks a good example of this.
