The best casino software developers

With so much choice of casino games, you probably do not even know where to start. We will help you by introducing you to the best online casino software manufacturers. The beauty of there being so many providers to pick from is that there is always a suitable manufacturer for everyone.


The Estonian company Playtech is known on the online gambling side mainly for its movie and TV slot machines such as Gladiator. However, this software developer also offers online casino software, business, and financial solutions in addition to their games. Currently, only a few online casinos can call themselves pure Playtech casinos, but this all-round offer should not be underestimated.


Based in the Isle of Man this company is widely known for its live casino, slot, and jackpot games. The slot Mega Moolah produced the highest jackpot win ever achieved in an online casino. Table games, bingo, poker, and some "movie-like" slot machines are also amongst its offerings. Recently, the possibility to play in virtual reality has been added to their already rich portfolio.


There is probably no online casino user who does not know of this Swedish online casino software. NetEnt has fought its way to the top of the worldwide represented game developers. Titles like Gonzo's Quest and Starburst are among the ground-breaking ideas developed by this studio. The fact that NetEnt also likes to include high bonuses in the form of free spins in its games, of course, also supports their popularity.

WMS Gaming

Williams Interactive is a US-American company with a long standing tradition, which, like Bally, now belongs to the Scientific Gaming group. WMS once produced pinball machines and arcade games but later switched to slot machines and eventually online slot machines. With Lucky Cruise, WMS also made the breakthrough into the worlds of social media offering its slot games on Facebook.

Play'n GO

The Swedish based company Play'n GO is another gaming provider that not only manufactures online slot machines, but also offers online casino software solutions for operators. As one of the youngest developers on our top list, Play'n GO has quickly made a name for itself on both the player and casino operator sides. The game Book of Dead will be a household name to anyone who has already taken a look at the world of online casinos.

Pragmatic Play

This relatively new game developer is already represented in many gambling related countries like Malta and Gibraltar. After all, their online slots have a lot of features to offer, which are very well received by players. Pragmatic Play shows what a slot machine is capable of and hereby breaks away from the standards. This approach is also applied to Pragmatic Play's live casino, table game, bingo and virtual sports betting software offering.

Nolimit City

Not only the name of this Swedish company offers unlimited possibilities. With a lot of humour, technical knowledge and a good eye for design, Nolimit City proves once and for all that slot machines are so much more than one-armed bandits. This developer's games are more reminiscent of computer games than traditional slots because of their sophisticated animations. If you are looking for an unusual adventure, this provider is highly recommended.


The name of this provider, which now has its headquarters in Malta, comes from Nordic mythology. Yggdrasil is one of the most innovative developers of our time and manages to cast a spell over everyone with its games. Especially the jackpot games seem to be a big hit with online casino users, titles like Vikings Go Bezerk and Dr Fortuno are a must in every well-assorted internet casino.

Evolution Gaming

Currently the hottest live casino provider in the industry. Evolution Gaming has offices in 13 different countries, with their headquarters in Malta. When live casinos first came onto the market, Evolution Gaming was not only one of the first companies to make this possible with its software, but even then, it was keen to help shape their future. So, the idea was born to offer game shows instead of just table games. These turned out to be extremely popular amongst players which quickly made Evolution Gaming the market leader in this respect.


Quickspin based in Sweden says it produces "the most amazing slot machines in the world". It is true that Quickspin manages to impress players with great graphics and to take them with their slots to strange/mystical/fantastic worlds. And it is also true that there are some features waiting for you that you have not seen before from other providers.

What you should know about online casino software providers

In the previous section we have introduced you to some of the best providers. However, there are many more game developers, so it is not always easy to find the one that suits you best. In addition, some of the developers differ greatly in what they offer. Some only make slots, others also have table and live dealer games in their assortment. Still others offer online casino solutions in terms of software, payments, customer service, marketing and much more. All of this determines on how many casinos the developer is represented and whether it is suitable for you. Apart from this, there are several other essential points that you should pay attention to when making your choice. We go into these in more detail below. In order for you to decide for or against a game developer, you should first know your wishes and preferences. Once you have this information, you can use the points that are important for you to compare the providers.

Security and certificates

In online casinos it is not up to the casino itself to determine how high the chance of winning a game is. This leads to the fact that this change of winning is generally higher in online casino games than for example in brick and mortar casinos. But that raises a problem. The fairness of an online casino game depends on the software developer and must be accounted for on their side. Although licensed casinos only offer games that are also licensed for the country in question, security comes first. Game developers should have a trustworthy license just like the casinos in which their games are offered. Only then can you assume that the underlying algorithms are regularly checked for fairness by independent companies. eCOGRA is such a company, a household name in the online gambling industry. With regard to licenses, there are no regulatory authorities separate from internet casinos, but for example the Malta Gaming Authority grants licenses to both casinos and developers.

It is also important that the technology is state-of-the-art. Only when a game is running smoothly you can enjoy it. Problems with unwanted game abandonment and other interruptions are some for the most annoying things there are for a player. The appropriate technical requirements must be met by both your side and the developer's side. Reputable slot machine brands always ensure that their games meet the latest requirements and that game histories are recorded for possible review.

Device Compatibility

Not everyone uses a Windows machine and a Chrome browser to play at an online casino. There are numerous devices with different software, and all games need to be compatible. Especially mobile casinos are a rather new invention, which is why there are games that are not compatible or only partially compatible with mobile devices. If you own a device with a less common operating system and / or use the online casino through a uncommon browser, it can happen that certain functions cannot be used properly if at all. Therefore, please ensure that the device you are using is compatible with the games of your preferred game developer and your preferred casino. This is the only way to guarantee that smooth online gaming is possible. Cancelling a game is not only annoying but can also cost you money.

Game offering

It is worth taking a look at the types of games that are offered. Does a developer only produce slot machines or does he also offer live dealers and table games? In addition, it is worthwhile to take a closer look at the respective category. If, for example, slot machines are offered, then there are also further distinctions such as video and jackpot slots. Do you like the selection of games and their implementation? If so, you can now continue to explore further. After all, many players are also interested in the small print.

What about the payout rate (RTP) of the individual games? The RTP indicates the average percentage of your bets that will be paid back to you after 100 spins. So, the higher the RTP, the better. In online casinos, slot machines usually have an RTP of between 95% and 99%. The volatility also gives you an indication of how the slot behaves during the game. High volatility mean that you won't win very often, but when you do you win relatively high amounts. Low volatility means that you are likely to win often but only small amounts. The number of reels, tiles per reel, symbols and paylines also allow you to determine if this slot machine is more financially rewarding than others.

Quality graphics and audio

We humans are true masters in recognising when something does not quite correspond to our reality. We make no exception to games. If we do not like the graphics, if they are badly implemented and if the musical underlay does not match the one displayed, we probably won't be happy with this slot. The best game manufacturers know that the eye as well as the ear play along with gambling. They skilfully use colours, animations, and music to let us participate in the game with (almost) all our senses. Of course, much of this is a matter of taste. So, make sure that the game appeals to you visually and audibly and that you have a completely satisfying online gaming experience.

Sometimes it can be that it is not due to the game, for example the audio sounds a bit scratchy. You should also check the settings of your computer or mobile device and their compatibility with the game in question. It may be that you can use the slot machine much better on another device, as there is no noise or other problems.

Supported Languages

Some casino entertainment is offered in different languages. Although the vast majority are only available in English, many games are also translated into other languages. For non English-speaking players or people that prefer their native tong, the regional game developers have a clear advantage in this respect. For example, Merkur and Novomatic are known for developing German slot machines, while MGA and R Franco service the Spanish speaking players.
