Slot machines are getting more popular than ever. With all these lockdowns we have witnessed in the past year and a half, itโ€™s no wonder that online casinos are recording huge profits. Among various casino games that are on the offer, slots still have a special place, despite their simplicity.

If you look at any online casino, you will see that most of its offer is about slot games. The highest reputable casinos usually offer hundreds or thousands of slot games, in order to attract more players. However, itโ€™s not just about numbers, but about titles as well. Thatโ€™s why most casinos include only games that come from renowned providers in their offer.

The market for slot games is huge. There are so many developers in the business these days but from what we can see, major houses rather stick with established names in the business. In other words, even though new game developers are coming every year, most casinos offer titles from those names that are familiar to players. Here is a shortlist of some of the best developers in the business.


When you are among the leading players in the business for 25 years, you know youโ€™re doing things in the right way. Thatโ€™s what we can say for NetEnt, a company that provides casino games since 1996. Todayโ€™s offer includes hundreds of titles and most of them are hugely popular among players. All games are characterized by a great playing experience. The easiness of use is what players like about these games, but we have to say that graphics are pretty impressive as well. When it comes to some of the most popular titles, some of the names that come to mind are Starburst, Gonzoโ€™s Quest, Lost Relics, Twin Spin etc.

Trustworthy Slots Providers


Although their games are not particularly popular in North America, the rest of the world knows very well about the qualities of International Gaming Technology. This is a company that has a huge experience in making slot games. They started decades ago, at a time when online casinos didnโ€™t exist at all. It was about traditional, brick and mortar slot games first, but modern online slot machines are as amazing.

The number of games this provider offers is huge. The company is particularly known for branded titles. Some names we should mention are CSI, Wheels of Fortune, Ghostbusters etc. All games are characterized by excellent graphics and playing experience.


Microgaming has been growing along with the growth of the online casino industry. Itโ€™s been around for decades and today, it is one of the biggest names in the business. This company provides all kinds of casino games, including slots, table games, live casino etc.

However, they are best known for amazing slots games. We all know the famous Mega Moolah series of titles, which received numerous awards. Of course, thatโ€™s not the only famous title from Microgaming, a company that has more than 500 games in its portfolio. We also know their branded titles very well, while the Game of Thrones slot machine is particularly popular.


We are pretty sure that there is no other game developer that has such an amazing portfolio. This company is responsible for so many legendary titles, starting from Age of Gods, Epic Ape etc. We particularly like their slot games that are inspired by famous comics, movies and video games. Some of the names that come to mind are Matrix, Gladiator, Superman, Dark Night, Justice League etc.

This provider has been in the business since 1999. For these 22 years of being in the business, they released more than 700 slot games.

RealTime Gaming

If you live outside North America, you probably arenโ€™t too familiar with this provider. On the other side, North American players know very well what the RealTime Gaming name means in the business. This is one of the key game providers among US-friendly casinos.

The company is currently based in Costa Rica, and it offers a nice selection of casino games, which includes slots, poker, table games etc. Interestingly, the actual number of games isnโ€™t huge. On the other hand, each game is characterized by tons of details, excellent graphics, great user experience etc.

ELK Studios

This provider is a relatively new name in the business, but it instantly established a high position on the market. Players like slot games from this company because they are innovative in so many aspects. For example, more players can connect and then compete against each other, gaining additional awards. Some of the most popular games are titles like Nitro Reels, Expanding Wins, Ice Climbers, and Buy Bonus.

New casinos have more new slots

New online casinos are generally better in adding the latest slot machines to their library than other casinos. Looking at comparison sites like Foxbonus, which is famous for adding the best new casinos to their list, itโ€™s obvious that the new casinos got more slots from lesser-known developers that generally purts out new games at a fast pace.
