Top New Slot Game Developers 2021

The new slots appear almost every month. This category of electronic entertainment is highly variable. The market rivalry is very tight today which is why the customer has plenty of possibilities to choose the best slot for his own needs.

The problem is the number of casinos. You cannot risk all your money in some shady ventures. The biggest issue with the reel machines is the same – there are too many of them. Moreover, some of the irrelevant slots may just be unbalanced. Therefore, you need a guide about vendors.

The term “new” here is about a slot itself, not a developer brand. The best casinos usually have their white list of vendors for decades. The pros of this decision are:

  • a small number of developers means good software compatibility. Many slot series are just reskinned with minor balance patches. So, the implementation of a new “one-handed bandit” will be quick and easy;
  • the gamblers shouldn’t train from the beginning every time. Every widely renowned vendor has established rules for years. The main strategies spread widely, there are a lot of gambling sites about dedicated methods for every known slot brand;
  • the unification makes the championships and some special events faster and with many participants.

Let us see what the biggest vendors of slot machines are for 2021. Spoiler alert: the prosper names are the same. We have seen the most popular casino brands. These software distributors are the true core of every modern online gambling house. If you know the main principles of their production, then you can master your gambling craft up to the skies.

Net Entertainment

It is one of the classic and the oldest Scandinavian vendor brands. NetEnt is famous for gameplay and posh background pictures. NetEnt started two decades ago. Its slots evolved drastically through the years.

The Scandinavian origin is only for the developers’ headquarters. Every new game under its umbrella is made primarily here. Nevertheless, with the global ambitions, NetEnt started hiring fresh blood from India and Asia. This was a wise move – the Asian market grows incredibly fast. Initially, NetEnt worked as a slots manufacturer exclusively. Today it provides you with table games and all the back-end operations for many online casinos. NetEnt also makes great efforts in mobile gaming.

Scandinavian countries hold strict policies. That is why NetEnt obtained Maltese, Gibraltar, and British licenses. In addition, it has papers from New Jersey. This is not a coincidence. Almost all the modern gambling rules were made in the Anglo-American world. NetEnt gives players hundreds of free and prepaid online slots with simple stakes, various bonus features, and shifting wilds.

Some top slots from NetEnt are:

  • the Gonzo’s Quest series;
  • the famous Starburst;
  • the rich jackpots of Jack Hammer.



It is an old and trusted reel machines vendor, too. Playtech is working like online casinos and mobile platforms equally. His path had started in 1999 from the production of multimedia software. The first online casino with Playtech machines was launched in 2001.

2009 was the year of real prosperity for this brand. Playtech signed an exclusive contract with a large William Hill casino. Then another big contract followed – with Marvel. The freshest franchise acquisition was a deal with DC in 2020. Playtech became the biggest producer of slots with superheroes.

Surprisingly, three of the most popular slots by Playtech are not comic-based. They are:

  • King Kong (not Peter Jackson’s franchise!)
  • Bonus Bears;
  • The Gladiator slots.


This is another famous developer’s name. For more than 25 years, Microgaming is the kingpin of slots with gorgeous drawn backgrounds. The company has delivered colorful slots since 1994.

The main benefit of Microgaming is hundreds of unique slots. At the end of 2020, there were about 850 games. Today there are even more. And it’s only casino versions! Many gambling houses work with Microgaming titles exclusively. Therefore, the very vendor name is a quality label.

Also, the studio does hundreds of mobile slots. At the beginning of 2021, there were over 350 of them. Even the most experienced high roller can choose a decent slot game. 3 or 5 reels? Posh 3D graphics or progressive slots? No problem! In addition, there are a lot of trial versions of almost every kind of game.

Microgaming fills the library with 10-20 new titles per year. Among the top slots, you can find:

  • the authentic Jurassic Park franchise;
  • the official Game of Thrones slot machine;
  • classic Mega Moolah and its later varieties;

Many of these games are produced by a seasoned model. For example, with the Game of Thrones slots, there were main events and new design features.

International Game Technology (IGT)

For some gambling magazines, this is one of the trendiest brands. IGT is one of the oldest market shareholders. They started in the early 80s when the Japanese developers introduced a new virtual gambling industry. IGT had begun as a small video poker software company. Today they are working with some of the greatest gambling franchises. They quickly presented new software in Vegas and Reno with the launch of the Megabucks video slot. The king of progressive jackpots came, along with the world record prizes. In the XXth century, the company expanded to the European market.

In 2021, IGT is famous for its “movie-themed” slots and such hits as Double Diamond and Wild Life slots. That is why the brand is actual and evergreen. Every media hit will be presented at the IGT games today. They all are browser-based, so the player does not need a powerful PC.

The major media slots today are:

  • the Sherlock Holmes franchise;
  • the Family Guy slots;
  • Gene Roddenberry’s Star Trek;
  • the Lobstermania 2;
  • classic Wheel of Fortune reel machines.
