Online Casino Software Providers

Similar to the diverse range of slot machines from different manufacturers in land-based casinos, US real money casinos often have hundreds (or even thousands) of slots and table games you can choose from. These sites will partner with a wide range of reputable software providers to guarantee a constant flow of up-to-date and exciting online game selections. 

Sure, online casinos themselves are responsible for bonuses and site layout, but the quality of your gaming experience hinges heavily on game providers. With the leading names in software development, you can expect smooth and immersive gameplay, swift load speeds, and no lag without worrying about malware and your online safety.  

But how do you know which game studio is best? That’s where US Casino Pros comes in; To ensure that we only highlight the best online casino software developers, we’ve put these companies to the test in our expert guide.

Top Casino Software Developers

Online and land-based casino players often weigh up many different factors when choosing slot games. These considerations may include themes, bonus rounds, volatility, RTP, betting limits, and more. However, many players streamline their search and focus on particular software developers that encompass all the above criteria. 

Top casino game providers likely boast extensive game portfolios containing something to suit most players’ preferences. We’re talking a wide range of volatilities and RTPs, tons of immersive themes, and slots with plenty of bonus rounds and mechanics.

Types of Casino Software Providers

No two casino software developers are the same. Each comes in different shapes and sizes, some even specializing in a specific type of casino game or gameplay mechanic. Let’s take a closer look at the different types of game studios you’ll find at our top-rated US online casinos:

Online Software Providers

Just as their name implies, online casino software developers create and produce games exclusively for online gambling platforms. These companies emerged with the expansion of online casinos and have significant expertise in crafting titles with top mobile capabilities. Whether you’re playing on your desktop, smartphone, or tablet, you can expect top-quality graphics and swift loading speeds. 

NetEnt, Play’n GO and Evolution Gaming and known for creating premium digital games for US players, stand out as major online software developers in the iGaming industry.

Land-Based Software Providers

Brick-and-mortar casinos have a lengthy history in the US. Initially known as saloons, gambling venues took on new forms with the emergence of riverboat casinos in the 1820s. After Las Vegas opened its first retail casino in 1906, only one year after the city’s establishment, land-based casino gambling continued to expand, as did the number of land-based software developers. These companies originally specialized in manufacturing physical slot cabinets and casino games. However, with the rise of online casino gambling in the late 1990s and early 21st century, these developers have adapted and evolved with the times to produce online casino games. Leading names like IGT, AGS, and Light & Wonder, who were once known for their physical slot machines, now also have extensive online game portfolios. Many of these titles are digital versions of their most popular land-based games.

Specific Game Category Software Providers

Certain software developers, such as Inspired Gaming, have built their expertise on specific casino game genres, offering a more focused, specialized, and premium gaming experience. Take Evolution Gaming as a great example. This provider has dedicated itself exclusively to the creation of top-tier live dealer games. These titles feature human dealers who actually handle cards, spin wheels, and more over HD live streams.  

There are many benefits to playing games from software developers who specialize in specific game categories. Perhaps the most important is that you get to play in a highly-specialized environment.

Niche and Specialized Software Providers

Last but certainly not least, we have niche software providers, who are independently run or often owned by larger game development companies. These smaller studios provide more specialized and niche games, usually supporting bigger studios and providing them with more unique titles with quirky themes and distinctive bonus features. Think of software companies like Fortune Factory Studios and ReelPlay.

What to Look For When Considering a Casino Software Developer

To help you pick the perfect casino software developer to suit your gaming needs, our casino pros have explained everything you need to look for:

Licensing and Testing

You should only ever play casino games from licensed and reputable software providers. Luckily, every game developer highlighted on this page holds licensing with respectable US regulatory bodies and is regularly tested by independent third parties to guarantee fair games.

Volatility and RTP

Whether you’re a budget bettor or playing with a larger bankroll, you’ll need to consider your gambling budget before playing casino games. Consider the RTP and volatility of slots to ensure you pick games that best suit your budget.

Bonus Features:

Consider the bonus rounds, game mechanics, and other features of a software studio’s games before playing for real money. Many players prefer games with more sophisticated features, such as free spins rounds, cascading reels, Wild symbols, and more, as they may give you extra chances to secure a payout.

Mobile Capabilities:

Is your favorite software developer mobile-friendly? If you prefer to gamble from the convenience of your cellphone or tablet, you should stick to more modern games that are built on HTML5 technology and optimized for mobile browsers.


Finally, you’ll want to make sure that titles from your preferred game provider are available at your favorite casino. US online casinos work with different software developers, so the games you find at one site may be very different from those at another.

Frequently Asked Questions

No. Casino games come down to random chance, and all reputable software developers use random number generators (RNGs), meaning there is nothing you, the casino, or the provider can do to influence outcomes. No matter the game and the software developer, the RNG technology will determine the result.

Not necessarily. Only software developers who hold valid gambling licenses with US regulatory bodies are legal in the country. We only feature licensed and reputable game studios here at US Casino Pros, meaning any games from these developers are safe and legal in the US.

Not at all. US online casinos will have different agreements with different software developers, meaning the games you find at one online casino may be vastly different than the titles at another. Still, all our recommended sites here at US Casino Pros feature plenty of online slots, progressive jackpots, table games, and live dealer options. 

Of course you can! While some older online slot machines may not be available on mobile devices, most modern casino games are responsive and optimized for smartphones and tablets. Thanks to HTML5 technology, you can play games via iOS, Android, or Windows Phone devices. Some US online casinos even offer dedicated apps for an even more bespoke mobile gaming experience.
