US Online Casinos – What’s Important 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.

Some talking points: trust/security/licensing, withdrawal speed, access to convenient payment options, customer support quality, mobile optimization, bonuses.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

FAQs

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.

The best online casino software providers 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 we 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.
