Slot machines are one of the main occupations of people who visit casinos. They are simple, fun, full of interesting motifs, themes, and games and, in addition, it is possible to make good money on them. Not a small number of people play slots and leave casinos or online platforms, which are summed up in one place, quite satisfactorily.

There are various slot games on the market. Their number reaches tens of thousands, and to be honest, we think that even the producers themselves are not sure how many of them they have launched so far. The best thing is that in the midst of the technological revolution, this entity, i.e. gaming industry, is growing progressively, and the developers themselves are expanding the market with new software.

You have probably never thought about it but the competition in the slot games market is huge, and there are several companies that are giants in this field and that are constantly competing. In essence, that is also the reason why we have such a good offer. In the next few paragraphs, we will introduce you to the largest and most important developers engaged in the production of software for slots.


NetEnt (formerly known as Net Entertainment) is a company from Sweden, which started operating in 1996 and has become successful in several fields ever since. But what interests us the most is its slot program, which they started building in 2005. After that, NetEnd profiled themselves as a company that produces only the best games, and which does not put economies of scale and abundance as the top priority. It does not have intrusive and complicated slots because it focuses on a simple design that enables high functionality.

At NetEnt, return-to-player is between 95 % and 98 %, which is far above the usual percentage of other competitors, and its games are therefore very popular. This company is collaborating with Universal Studios and will use its characters and movie motifs in the future. By the way, it already had one ultra-popular product from that collaboration, the legendary Scarface, a game that is one of the most famous in the world of slots. Besides, Gonzo’s Quest, Jack Hammer, Starburst … are all NetEnt’s games.


Unlike NetEnt, Microgaming does aim to reach big numbers as it has over 760 games on offer. However, that does not mean that it is of lower quality than anyone else, but quite the opposite. Microgaming was founded in 1994 on the Isle of Man and is the creator of the so-called “243” slots because they devised 243 ways to make a profit, i.e. paylines.

What sets it apart from the rest of the competition is two-way playing: online via a browser and downloading from the Internet. The webinar software that makes this possible is called Viper, and in that case, you have practically the entire casino installed on your computer. It is very important to note that Microgaming is largely responsible for the emergence of online casinos because it itself participated in the creation of the first. The most famous games of this company are Immortal Romance, Thunderstruck, Avalon, Jurassic Park, and Terminator. They also offer Game of Thrones.


This is a pioneering company in making slot games. It started working in 1980 in Austria, making traditional machines that flooded the world at that time. Novomatic is by far the most famous on the market, and earlier you could see at least one of its machines in literally every casino. We will only mention Gaminator.

Since 2011, it has entered the waters of online casinos and flooded the Internet with its products. Unlike all other competitive game developers, Novomatic provides a 50-50 chance at gambling, i.e. you choose either red or black. The most famous games of this manufacturer are Book of Ra, Sizzling Hot, Lucky Lady’s Charm, and almost all of these editions have Deluxe added at the end of their names.


Founded in 1999 in Estonia, it is also one of the main brands on the market. It bases its popularity on interesting motifs of games in which it uses, for example, the heroes of Marvel comics, which attracts a lot of players’ attention. Playtech seems to have focused particularly on that type of production as it has signed a contract with NBCUniversal, HBO, and Marvel, hinting it will have a huge number of such releases soon. In some countries, Playtech is known for collaborating with national lotteries for which it makes online poker and casino games.
