Top 5 UK slot producers

Slot machines are one of the most played games in the gambling industry. This is largely due to the fact they’re easy to play, are hugely entertaining, and can result in a massive jackpot if you’re lucky.

Online casino popularity is on the rise in the UK, and slot producers are playing a significant role in this growth.

Over 70% of people visit online casinos to play slots. And depending on their experiences, they could revisit these websites or find new casinos.

The top 5 UK slot providers rely on several factors to stay at the top of the industry: their reputations, innovation, marketing, flexibility, and adaptability. Possessing solid reputations commands loyalty from online casinos and players. Being innovative helps developers create games people will love while they must stay flexible and adaptable to keep up with industry trends.

This article takes a detailed look at the top 5 slot providers in the world. What makes them stand out from their competitors? What are their strengths and weaknesses?


Isle of Man-based Microgaming is the world’s leading slot provider. It is also a pioneer in the online gambling industry, having created the first online casino in 1994. The developer also launched the first mobile casino in 2004, which says a lot about its adaptability to new technologies.

Although Microgaming provides both table games and slots, most people know the company for its extensive slot selection. The award-winning developer has over 850 slots in all major categories. Here are some of them:

  • Game of Thrones
  • Mermaids Millions
  • Avalon II
  • Thunderstruck II
  • Spectacular

Of course, it would take days to describe all of Microgaming’s slot machines. As such, most people play the best-rated slots, all those known to pay out frequently. Its record-breaking jackpots like Mega Moolah are also famous for paying out millions of pounds to winners. In the table games department, Microgaming creates poker, blackjack, baccarat, craps, and roulette.

Microgaming’s Strengths

  • Biggest Library of Slot Games—you won’t find a company that publishes as many online slots as Microgaming anywhere in the world. And considering the company produces new games each month, it will continue to boast of the largest game portfolios.
  • Licensed by Multiple Companies—Microgaming is permitted by all respected online gambling regulators. From the UKGC to Gibraltar, the MGA to Curacao, the company is authorized to provide games in hundreds of countries worldwide.
  • Certified for Fairness—all of the developer’s games have been certified as fair. That’s a crucial aspect of games as it confirms you have a decent chance of winning. So, whenever you play Microgaming’s slots, you can be confident they are safe and fair.
  • Games available in 100+ casinos—Microgaming slots are offered on numerous casino sites throughout the UK. And since the developer picks casinos it works with wisely; many Microgaming casinos are reputable.

Microgaming’s Weaknesses

  • Games are not of Equal Standards—although Microgaming provides high-quality games, not all of its titles possess the same level of quality as its signature games: Mega Moolah and Thunderstruck II.
  • Can be Overwhelming to Find Good Games—with such an extensive library of games, sorting out Microgaming’s slots can be challenging. Luckily, you can always search the best-rated games or read online reviews to know which titles to play.


Netent has been Microgaming’s most fierce rival since its launch in 1996. Whether it’s in producing mobile games or jackpots, Netent’s name regularly comes up when Microgaming’s competitors are mentioned.

And while the Isle of Man developer boasts of more games, Netent owns most of the most famous slots. You probably already know about these slots: Starburst, Netent, Twin Spin, and Mega Fortune Jackpot games. But visit this guide for a detailed overview of Netent slots ranked by popularity. You’ll find a lot more games not always promoted by casinos despite having incredible storylines and high payout rates.

Speaking of payout rates, Netent features over a dozen games with a return to player rate of at least 96%. A high return rate increases the odds of winning games even though it doesn’t guarantee you always win. Take a look at these Netent games with payouts:

  • Mega Joker—99%
  • Blood Suckers—98%
  • Kings of Chicago—97.8%
  • Fishy Fortune—97.9%

Netent also leads the slot industry in most games that support virtual reality. For the uninitiated, VR is a nascent technology that immerses you into the gaming world so that everything in the real world stops existing for a moment. Netent is the proud developer of these VR games:

  • Gonzo’s Quest
  • Jack and the Beanstalk
  • Starburst
  • Miss Midas

Apart from slots, Netent also supplies table games and live dealers to online casinos. Some of its table games are American roulette, blackjack, European roulette and live tables for all these games.

Netent’s Strengths

  • Comprehensive game portfolio—Netent features more than 500 slots. Similar to Microgaming, the Swedish developer is continuously updating its portfolio. So, if you don’t want to play its most famous games, you can sort out through hundreds of titles to find unique games.
  • Highly innovative and quality-oriented—Netent leads the way in innovation. Games like Gonzo’s Quest and Starburst became famous for introducing features that previously didn’t exist. Most Netent games also feature high-quality graphics, sounds, and other features that make slots enjoyable.
  • Available in hundreds of casinos—Netent is one of the most in-demand software providers. Nearly all the top UK online casinos provide its games, even the least known titles.
  • Certified Fair and safe Games—like Microgaming, Netent’s games are verified by multiple independent auditors and certified to be safe and fair.


  • Games restricted in many countries—Netent isn’t licensed to provide games in all countries. Due to that, you can’t access its games if you reside in Poland, North Korea, Cyprus, and other countries with strict anti-gambling laws.
  • Software can’t be downloaded—if you prefer to play slots on downloaded software, Netent won’t be your provider. The company provides instant-play games that you can quickly access online.


For some, Playtech is the best online slots provider in the world. That’s because it’s created a range of impressively cool titles like Superman, Justice League, the Flash, Wonder Woman, Top Gun, and The Matrix. In casino jargon, these games are called branded slots and require paying for licenses before a developer creates them.

Of course, Playtech isn’t the only developer that supplies branded slots. The company also specializes in non-branded casino games, including table games. In fact, one of Playtech’s defining qualities is the ability to provide all sorts of games offered at online casinos.

Some of Playtech’s major casino partners provide the developer’s games exclusively. A few famous examples are Casino Las Vegas, Eurogrand Casino, and Titan Casino. A lot more websites offer Playtech plus in combination with other developers.

Nonetheless, the 1999 launched company is one of the most successful slot providers in the world. Its games are mobile-friendly, high quality, and endowed with bonus features and random jackpots. Here are five of Playtech’s most successful slots:

  • Desert Treasure
  • Cinerama
  • The Matrix
  • American Dad
  • Top Gun
  • Buffalo Blitz
  • Big Bad Wolf
  • Tip Top Totems

Being a top slot provider, Playtech also invests a lot in the quality of its games. The publicly listed company knows it’s continually competing with equally resourceful developers. And because it prefers to impress casinos by offering outstanding games, it must keep offering top-notch slots.

Playtech Strengths

  • Huge Financial Muscles—Playtech believes in growth, and it does this by regularly buying upcoming software developers. Its most publicized takeovers include Quickspin, Mobenga, Ash Gaming, IGS, and Virtue Fusion. The LSE listed company also keeps acquiring licenses to crate exclusive branded slots, something that helps enhance its brand.
  • Attention to detail—Playtech’s games all feature high-quality graphics, impressive soundtracks, and incredible storylines. It’s a testimony the developer values quality and rarely publishes a game unless it possesses high standard features.
  • Wide range of games—the Estonian developer has more than 600 slots, table and games, bingo, lotto, scratch cards, and sports betting. That’s why it’s such a reputable company that some famous casinos only provide games from the developer.
  • Safe and Certified Games—similar to its peers, Playtech’s software is verified by independent providers to confirm its games are safe and fair.
  • Available in both download and instant play modes
  • Games available in over 100 jurisdictions


  • Some Playtech casinos limit maximum payouts for progressive jackpots

Betsoft Gaming

Established in 1999, BetSoft is one of the pioneers of online slots. It’s also an innovative company that takes pride in owning some of the industry’s most popular 3D slots. And like its peers, BetSoft has a decent portfolio of table games like poker, baccarat, roulette, and blackjack.

Another distinguishing feature of BetSoft is that it offers both free and real money slots. So, if you want to test the company’s games without spending money, you can play a few of its free slots.

BetSoft Strengths
