Online Casino Software in the US

Discover the best casino software providers and learn what makes them great. This page features all the most popular game suppliers across US casinos in states like New Jersey, Pennsylvania, and Michigan.

We also cover what’s important besides software and why the casinos we recommend are selected based on numerous criteria like trust, payout speed, and customer support.


Casino Software Providers


Attributes of Trusted Casino Software Providers

We’ll go through what makes a good gaming supplier. This is the criteria we use to judge the various gaming suppliers on the market. The goal is to make sure we present legitimate gambling softwares with a good reputation and a great range of well-paying games.

    Security and compliance

    The best software providers show trust by respecting regulations and complying with all rules and guidelines set by state regulators such as the NJDGE. Just like online casinos, gaming providers must obtain and regularly renew their gambling software licenses. Maintaining a license is constant effort, and it involves regular audits to verify the integrity of the software provider’s random number generators.

  • fair play
    Game selection

    The essence of every gambling software provider is their game selection. It’s the biggest factor that separates the best from the rest. For example, a provider like IGT is iconic in the gambling world, but today they don’t have the quality of NetEnt, and are lagging behind in features, graphics and variety. Reputation can go a long way but the entertainment value and payout rate of a provider’s games are ultimately the deciding factor.

    User interface and features

    Usability is crucial and some software providers such as NetEnt and Big Time Gaming are miles ahead of the competition here. Usability includes useful features such as auto play and quick play, easy stake adjustment, a well-defined pay table, mobile compatibility and speed. You will find these features, and some provider-specific features, in nearly every game, but the way in which they’re implemented make the real difference.

    The innovators such as Big Time Gaming with their Megaways slots have shown how a relative newcomer can break through the top in a flash. NetEnt is also known as a big innovator, spearheading mobile compatibility to the next level in modern online casino gaming. Then there are names such as IGT and Greentube who’ve shaped the industry before online casinos were barely a thing. Overall, many providers deserve merits for innovation – whether through small quality of life features, or big headliner games – they’ve elevated the industry as a whole.

    Payout percentages

    The payout percentages, represented by RTP (Return to Player) percentage are usually a sign of a provider’s style of games. An typical slot will have an RTP between 93% to 97%, which is considered average. Software providers who make games with extremely low RTP, such as below 90%, are not worth looking into. These kind of payouts are mostly found in outdated games. We focus on modern providers with great payout rates on top of high entertainment value.


What is Important in a Casino Besides Software?

The gambling software selection is only one piece of the puzzle. We don’t evaluate casinos based on casino games software alone because other important factors play a huge part in ranking and reviewing.

Have a look at our main points when reviewing casinos partnered with the top online casino software providers.

Traits of trusted online casinos

  1. Trust and security – The first and most important thing is having a legal US license for the states a casino wants to operate in. We also look at the brand’s history and any recorded penalties and complaints to ensure you’re playing at a fair, trustworthy online casino.
  2. Fair play – It’s important for us and players to make sure players can control their spending through tools like deposit limits, loss limits, wager limits, and session limits. The option to self-exclude and a “cool-off” period are important as well.
  3. Payment options – The range of payment options determines how easy you can deposit and withdraw. The more variety, the better it is for players. We look at casinos with varied types of payment options, such as in-person, e-wallets, prepaid vouchers, and credit/debit cards.
  4. Withdrawal speed – The withdrawal speed is a priority when looking at payment options. That’s why we hold e-wallets in high regard – payouts to this method are usually completed in a day or two. We only select casinos with reasonable withdrawal timeframes because holding your money hostage is a big no in our books.
  5. Customer support – It’s almost guaranteed you’ll need help from customer support while playing. As such, having a responsive, widely available live chat service with friendly, courteous support agents is crucial in our evaluation.
  6. Bonuses and promotions – Many players want bonuses, and most US online casinos offer excellent welcome package offers. But we prioritize casinos with fair bonus terms as the ultimate factor. We also consider rewards for ongoing players – like VIP programs, comp points, deposit match offers, cashback, and free spins.

It should be noted that many providers can’t launch all their games in the US because of specific state regulations. In reality, some of these gaming suppliers have produced many more games over the years, and plenty more will arrive on the US market.

Not Recommended Software

The Internet is flooded with illegal “US online casinos” with software that is licensed off-shore. Legally, people can debate if playing at these sites is a grey area. But, one thing is for sure: the law can’t protect you if you get cheated by an online casino using unlicensed software.

These are some of the most popular online casinos being falsely advertised as legitimate US sites. There are even more out there. For your own safety, always check and verify a casino’s license information before playing.


Online casino softwares are still growing in the US. Most of the top providers still haven’t transferred their full range of games. On top of that, many aspiring newcomers and industry veterans are looking to make their mark as well. Providers like NetEnt, IGT, Big Time Gaming, and others, have established themselves at the top. It remains to be seen whether they will be challenged by innovative newcomers or existing providers, but one thing is for sure: more competition will always benefit the players!



A casino software provider creates or distributes games to online casinos. The software providers usually design the games and then license them to online casinos at a fixed cost, or a deal is made for a portion of the casino’s profits from those games.

From the available online casino software providers, the ones that stand out the most are NetEnt, IGT, and Big Time Gaming. These casino software providers are our top 3 picks, but dozens of quality game studios partner with US online casinos. We list all the common and popular providers and have a dedicated page to each. There, you can learn the best casinos for each software and in-depth info on games and payout rates.

All casino games software must apply for a US license and pass mandatory security checks to ensure that their games are fully legitimate. This means legitimate RNG (Random Number Generator) through rigorous testing and frequent audits to ensure proper payouts and no software tampering.

Online casino software is tested by the license issuer by simulating millions of game rounds to ensure that the Random Number Generator is as advertised. They also monitor the games once they make it live in casinos and perform audits to ensure that that overall payout fits within the RNG and its margin of error.

You can find free online casino software at any US operator and enjoy playing games for free, in demo mode. All you need to do is create your free casino account, and you can play. To win real money, you will need to make a cash deposit and play real money games. The exception are live dealer games which can’t be played for fun.

No, you don’t have to download casino software. The top US online casinos work with HTML5 technology, which lets you easily and instantly access all games directly through the casino website. This applies to desktop and mobile as well. The best US casinos also offer native apps you can download on your iPhone, iPad, or Android, but you don’t have to.
