What Is a Slot Provider?

A slot provider is an independent company that creates and supplies online and brick-and-mortar casinos with slot games. 

With these games becoming increasingly popular and overlapping classic table games like poker, and blackjack, new slot providers are popping up constantly in the iGaming market.

These slot websites are structured as any other gaming company, employing graphic designers, game artists, developers, programmers and game testers.

Over the years, certain game providers have made a name for themselves and backed their reputation with high-quality slots.

Microgaming and NetEnt have been around for a couple of decades, and almost all UK players have come across some of their games.

The best thing about this sector of the iGaming market today is that the competition is improving with each passing day, meaning gamers can enjoy more top-tier slot games.

Slot Standards for the Best Slot Providers

  • Number of paylines 
  • RTP
  • Volatility
  • Animations
  • Sounds

The most popular type most slot sites have developed today are video slots, and they mainly focus on putting out 5-reel titles with all kinds of themes. Compared to the graphics from a few years ago, we can see significant improvements in the animations today.

On the topic of bonus features, to get players interested, slot providers incorporate free spins, multipliers, clusters, mini-games, wheel spins, and many other in-game features. 

Furthermore, the RTP must be at the market’s average, at 96%. 

Regarding volatility, it all depends on the creator, whether they want high volatility, meaning wins don’t come as often but are significant when they do, or low volatility – more wins but lower payouts.

Pragmatic Play Slots

With less than a decade in the iGaming world, Pragmatic Play has made enormous leaps and become one of the biggest software providers in the industry. 

Founded in 2015 and based in Malta today, the company is known for creating some of the most exciting slots and live dealer games.

If we look at some of the best titles they have created, they focus on creating titles with high RTP. 

Some of their most famous slots include Book of Tut, Sweet Bonanza, Gold Train and Great Rhino Megaways – all of which have an above-average RTP.

Wolf Gold

Released in 2017, Wolf Gold is the most famous slot from Pragmatic Play. This 5-reel, 25 payline title has a wild western theme, including some popular animals from western America.

You can see wolves, eagles, bison, cougars, stallions, and others.

The game has standard features like a scatter and wild symbol and a free spin bonus round.

The bonus round can be activated if you hit six money symbols represented by a moon. It has an RTP of 96.01% and comes in medium volatility.

NetEnt Slots

When talking about slot provider royalty, NetEnt is sure to be mentioned. This seasoned veteran has been around for over two decades, paving the way for all software developers today.

NetEnt casinos offer some classics, including Gonzo’s Quest, Starburst, and Dead or Alive.

The provider was one of the first game developers to acquire licenses to create slots based on popular movies and TV shows such as Jumanji, Narcos, Vikings, The Invisible Man and many more. 


Although it is one of their older games, Starburst remains the best online slot that NetEnt has created. 

The whole theme revolves around jewels, with a 5×3 grid. There are ten paylines, and the betting range goes from £0.10 to £100.

The in-game bonus feature is a re-spin that can be triggered when a player hits five wild symbols. 

The maximum win is set at 500x the player’s initial bet. The game sports a 96.09% RTP and is declared a low volatility slot.

EGT Slots

Starting their company as a slot machine cabinet manufacturer, EGT or Euro Games Technology has been around since 2002. Once they got their official license, they started expanding, covering Europe and Central and South America. 

As time went by, the company noticed the shift toward online gaming and started making online slots.

Some of their more popular titles include 100 Cats, 20 Diamonds, Almighty Ramses 2, Casino Mania, and Aztec Glory.

40 Super Hot

Although they have a long list of games, their top option is the 40 Super Hot slots. If you remember 20 Super Hot, this newer addition has more paylines and better mechanics.

40 Super Hot has a 5×4 layout and 40 fixed paylines. Like its predecessor, the game revolves around fruits, and you will find symbols such as grapes, lemons, watermelons, oranges, cherries, and plums.

A star and the wild by the number 7 represents the scatter symbol. There are two bonus games called Risk Round and Jackpot Cards. 

The game has a below-average RTP of 95.80% but boosts low volatility.

Microgaming Slots

Microgaming is one of the oldest developers and a well-known online slot provider in the iGaming industry. 

It started operating in 1994 and has become one of the leaders in creating casino games. Today, we can approximate that the software vendor has made more than 800 different titles.

Some of the more notable titles you can find on Microgaming casinos include Immortal Romance, Mega Moolah, Six Acrobats, Thunderstruck 2, Book of Oz, Wanted Dead or Alive, and 9 Masks of Fire.

Mega Moolah

One of the most well-known slots in all reputable slot sites is Mega Moolah. This game has been around for more than 15 years and still holds its ground against some new and well-designed titles. 

Since its release in 2006, it has gotten some additions; however, the original game has stayed at the top.

With a 5×3 grid and 25 paylines, players can bet between £0.25 to £6.25 per spin. The African safari theme features numerous symbols including an elephant, buffalo, giraffe, zebra, impala, and lion. The monkey symbol represents the scatter needed to trigger 15 free spins. The title has low volatility and an RTP of 88.1%.

The main reason everyone knows the slot is because of its Mega Jackpot. It is the biggest progressive jackpot online. There are smaller in-game jackpots called Mini, Minor, and Major.

Play’n GO Slots

Another huge name in the iGaming industry is Play’n GO. Founded in 2005, the company is known for making ground-breaking steps towards gaming on the go. 

Based in Sweden, with over 280 slots, Play’n GO knows how to operate in the market and what players want.

The most popular games you can find on Play’n GO casinos include Fire Joker, the Rich Wild series, Spin Party, Sea Hunter, Moon Princess, Legacy of Dead, Reactoonz, and more.

The best part about the company is that every new game they develop is compatible with mobile devices.

Rich Wilde and the Book of Dead

The Book of Dead is the most popular addition to the Rich Wilde slot series by Play’n GO. The game has a 5×3 grind with ten paylines, and players can make bets from £0.10 to £100 per spin. 

The game’s theme is based on Ancient Egypt, so you will see a specific design for the symbols, background, and even the soundtrack.
