Top online casino providers create fun, bold, innovative and feature-rich games that keep you entertained. Simple as that. To help you understand different types of slot providers, and other gaming studios on the market, Mr. Gamble created this useful guide. Dive right into it to explore your options and choose the best casino operator with the hottest releases.

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.

What Are the Best Types of Online Casino Games?

There’s a wide variety of online casino games available at your fingertips. Broadly, there are three main formats that will all use different software:

  • Video Slots
  • Mobile
  • Live Casino

Each will have small differences to offer the best possible gaming experience to you, the user.

Video Slots

Video slots can be summarised as the most typical slot you’ll find at your favourite casino. When you go on a browser and click over to the Slots section, you’ll find a variety of games, often ranked by most popular and often from the top slot game providers.


Mobile software is different. Some players prefer to be perched in front of the tv, watching the football while having a spin. Often desktop games are not specifically engineered to be mobile-friendly, and the experience on mobile or tablet can almost be jarring. Nowadays, slot providers have become wise to this – and there’s plenty of games specifically designed for mobile casino users, or video slots have been adapted to be more mobile-friendly.

Live Casino

Live casino software is a different ball game altogether. Often there’s nothing better than being in the casino yourself. Playing Blackjack against a computer seems less authentic than against a real dealer – and live casino is designed to bridge that gap precisely. Brought to you from studios all over the world, live casino gives you an experience almost identical to being out on the casino floor yourself – and there’s plenty of games available now too.

What Is a Casino Software Provider?

A software provider is a company that, in most cases, specifically designs slots and games to be played on online casinos.

Recent technological development and increased competition in the market have led to a huge amount of innovation, and now there’s so much choice you’d struggle to find a game that doesn’t fit what you want to play.

The majority of games you play now will not be developed by the casino you’re playing with. Instead, they’ll be developed by a third-party, specialist software provider like NetEnt. Most casinos will often have contracts with multiple providers to offer their users a wide variety of different games. We’ve detailed the differences between casinos and software providers below.

What’s the Difference Between a Casino and a Software Provider?

Historically, a casino and a software provider would have been the same thing. In the very early days of the gambling industry, each gambling company would do most things themselves. As the industry has developed and evolved, very few now do. Innovation from third-party companies (now top software providers) led to online casinos putting their resources elsewhere, and offering better games (at a lower cost) to their users. This also enables the launch of new online casinos without having to develop games in parallel.

Another difference is the type of gambling licence held by the company. Gaming companies can hold one of two licence types. The first is a B2B – Critical Supply Licence, which allows a company to ‘provide a supply in a business-to-business capacity’. The second is a B2C – Critical Supply Licence which gives ‘a licence to provide a service for the purposes of engaging with end consumers.

Each licence comes with a different set of rules and regulations that must be adhered to, and although some companies may hold both, it’s more common to see them split accordingly. As always, we recommend checking the certificates of any casino or provider you may use.

Who Are the Top Slot Providers?

You may not have heard of the top slot providers, but you’ll definitely have heard of their slots. Here’s five of the top casino slot providers, and some of their most popular games:


There’s plenty of different game studios under the Playtech umbrella, as the company has continued to become one of the biggest in the industry. The company boasts over 700 titles and continues to churn out some of the very best year-on-year. Some of the most notable titles are as follows:

  • Age of the Gods
  • Jackpot Giant
  • Justice League
  • Superman
  • The Dark Knight
  • The Matrix
  • Gladiator

As you can see, Playtech’s a giant of a slot provider, with premium licences and film tie-ins across the board. If you’re playing a Playtech game, you can have no doubt about the reliability, although picking your favourite may be a little tricky with so much choice on offer. 

International Game Technology (IGT)

IGT is another behemoth of the slot world. With famous Wheel of Fortune slots, and multiple well-known jackpot titles, it’s another that will feature in several of your favourite online casinos. The company claims to have the largest number of game themes in the industry, and there’s little doubt you’ll have ample choice if filtering by IGT. The studio releases upwards of 175 new titles a year, so there’s never a shortage of fun to be had. Here's a few of the most famous:

  • Wolf Run
  • Golden Goddess
  • Cleopatra
  • Wheel of Fortune
  • Pixies of the Forest


Isle of Man based Microgaming has paid out over €1.3 billion in prizes through its progressive jackpot network to date – showing the sheer size of the provider. The Microgaming library holds over 800 casino games, and like the two aforementioned providers, has a steady pipeline of new releases to service every market. You may have heard of these:

  • Jurassic World
  • Game of Thrones
  • Thunder Struck
  • Wheel of Wishes
  • Mega Moolah

These are not the only top slot providers available, but they’re up there with the most common names you’ll see appearing at your casino of choice.

What Is RTP and What Does It Mean?

RTP is a term that you may have seen pop up while playing casino online. The acronym stands for ‘Return to Player’ and is used to explain the percentage of money that a casino slot will return to its customers.

The calculation for RTP is not overly complicated. It’s effectively the total amount of money returned to players, divided by the total amount of money wagered by players. You may see RTP banded about and labelled on a lot of online slots, or games that you play, but these shouldn’t always be taken at face value.

A lot of slots will offer RTP values of around the 95-96% mark (and are actually required to hold a minimum % by regulators). This should typically mean that over a period of time, the majority of your money will be returned to you. This will, of course, vary per player and is rarely accurate for any single player. It can be easily skewed by those that get lucky and win jackpots, while the average punter doesn’t net a huge win.

There’s also some that prefer to play games with a lower RTP out of choice. Some games are considered ‘higher risk’ by having a lower RTP, but with a larger chance of a big win. These are not always disclosed, but in recent years the gambling industry has been required more and more to disclose elements such as RTP. If you’re interested, you’ll likely be able to find the RTP of any slot you’re playing.

What is RNG?

RNG is another acronym often seen in online casinos. To completely oversimplify, RNG stands for random number generator and is often the system used in the algorithms behind each slot. It’s coding that is engineered into the game that means each player has the same chance to win as the next. All of that rubbish you heard about machines being hot and cold is actually just rubbish – with RNG involved, the system has no memory so each spin is as random as the next.

Which slot game prociders pay out most?

The million dollar question: which slot game providers pay out most? The answer is simply, we don’t know. With every casino game, there’s an element of luck involved. As we’ve previously explained the premise of RTP, make sure you familiarise yourself and then you can have a better understanding on a game-by-game basis. You’ll find that most online casino games sit at an RTP of between 94-97% these days.

There will of course be bigger jackpots with certain bigger providers. Those playing progressive jackpot slots will find occasional mammoth wins for consumers that are not ordinarily available elsewhere.

Who are the biggest casino software providers?

We’ve previously mentioned three of the biggest in Microgaming, Playtech and IGT but other notable names include Real Time Gaming (RTG), Net Entertainment (NetEnt), Pragmatic Play, Evolution Gaming, Play'N Go and many more.

If you particularly like one game you’re playing, then check who’s behind its development and you may well find other games that you enjoy similarly.
