How We Select the Best US Online Casinos

As we mentioned, only the best US online casinos make it onto our list of recommended sites. We put every casino through a stringent vetting process and only those who score consistently high will make it. We try to find a range of sites to suit all types of players.

To ensure the best online gambling experience, our criteria checklist for the best US online casinos includes safety, banking, withdrawals, security, bonuses, reputation, games, software and overall performance. Let’s take a look in more detail:


Top of the checklist for any player must be the licensing status of their chosen online site. All reputable online casinos will be licensed and regulated by an official gaming authority. Look out for the licensing details at the footer of the casino’s website and/or within the general terms and conditions.

In the US, players may find sites licensed by Costa Rica, Panama or Curacao and for those wishing to register with casinos outside of the states you should be looking for licenses held with MGA, UKGC or KGC that regulate under the strictest of guidelines

Malta Gaming Authority (MGA)

Founded 2001. Adheres to European laws promoting safe and responsible gambling

United Kingdom Gambling Commission (UKGC)

Founded in 2005. Follows strict guidelines in protecting the vulnerable by promoting fair and safe gambling

Kahnawake Gaming Commission (KGC)

Founded in 1996. Licensing authority for gaming activity from and within the Mohawk Territory of Kahnawake


Registering with an online casino requires players to share sensitive data and financial information along with depositing your hard-earned dollars. It is important for you to feel protected and secure when conducting online transactions.

For the safety aspect, the online casino must be licensed by a recognized authority. For the best US online casinos to pass all of our security tests they must tick off the following while on the flip side is a list of red flags to watch out for and at all costs avoid.

  • Be licensed and regulated by an official gaming authority
  • Use the latest encryption technology to safeguard data and financial transactions
  • Utilize third party auditors e.g., eCOGRA to monitor RTP and RNG stats

The best US online casinos offer a diverse and wide range of casino games which are provided by top quality software providers. All reputable casinos are subject to third party auditors e.g., eCOGRA, iTech Labs, who monitor RNG (Random Number Generator) and RTP (Return To Player) stats for compliance with fair gaming protocol. 


Powering this wealth of diverse and popular online casino games are some of the world’s top class software developers. Here are a few of the industry giants you can expect to find at the best US online casinos:

Evolution Renowned leader in the development of the best live casino platforms, pioneers of live game shows such as Crazy Time, Monopoly, Deal or No Deal
Big Time Gaming Recognized for development of the revolutionary Megaways reel mechanism enabling up to 117,649 ways to win which has been licensed for integration into hundreds of slot machines
NetEnt Creator of legendary slots like Starburst and the record-breaking progressive jackpot Mega Fortune, features in 200+ online casinos around the world
Playtech Second only to Evolution for live gaming platforms, has developed over 700 slots and offers table games, bingo and sports betting, opened the world’s biggest independent online poker school
Microgaming Pioneers of the world’s first online casino software, a wealth of casino games including several branded slots for instance, Jurassic World and record-breaking progressives such as Mega Moolah

Bonuses and Promotions

As the online casino industry is such a competitive market, operators will change and update their bonus offers on a regular basis to appeal to the next potential customer. This is where new players can capitalize on tempting deals and bag a welcome bonus fit for a king.

Online casinos demanding 50x wagering requirements or above plus short ‘valid for’ time limits are not worth your time, money or energy and should be avoided at all costs

However, there are also plenty of unscrupulous sites as we mentioned earlier and the grass is not always greener. Some bonus offers are really not as good as they first seem, scratch below the surface to find extremely high wagering requirements with nigh on impossible playthrough conditions.

Our team of experts vet every bonus and promotion offered by an online casino, they want to make sure that all players get a fair crack at the whip. Those that make it onto our top ranking list will offer a mixture of bonuses including deposit matches and cashback offers.

Let’s take a look at some of the popular bonuses and promotions you can expect to find at the best US online casinos:

Welcome Bonus

First impressions count or so they say! The welcome bonus is often presented as a match deposit with a few free spins thrown in e.g., 100% match deposit up to $1,000 + 50 Free Spins. To claim the welcome offer, it will usually require a minimum deposit of around $10 to $20. It’s important to read through the bonus terms to ensure the wagering requirement and time limits are fair and achievable (below 50x and usually 7days +). More often than not, the free spins will be for play on designated slots, however, they’re free and fun to play. (1)

No Deposit Bonus

These are few and far between but there are still some no deposit bonuses to be found. They are often quite low in value though and more often offered as a free spins welcome bonus as opposed to funds. It may only be 10 to 30 bonus spins but you don’t need to spend a dime to play and it allows you to test out the water with a new online casino.

Free Spins

As mentioned earlier, free spins can often be combined with the deposit match welcome bonus or be offered as a no deposit bonus for sign-up at the site, however, the best US online casinos may also promote a free spins bonus during the week for existing players.

Cashback Promotions

Cashback may be offered for online casino games and/or the Live Casino games. It is a percentage awarded back to the player based on losses and typically for those generated over the preceding weeks wagering. Cashback is an incentive bonus for loyal players and although the percentage offer isn’t typically high, it’s still money back. An example bonus may look like this – 10% up to $500. Ranges will vary between operators and usually float between 5% to 20% with a ceiling of $1,000.

Reload Bonus

Reload bonuses are for existing players and usually take the form of a match deposit, for example 50% up to $200 and is yet another rewarding incentive for the existing player base. It may be promoted as a mid-week special or weekend kickback offer.


The best US online casinos will offer multiple trusted and reliable payment methods that are recognized within the iGaming community. Methods can vary slightly from country to country but generally there are a few favorites which are widely available at most online casinos:

  • Cryptocurrency
  • Visa Credit/Debit
  • MasterCard
  • Western Union
  • Pay By Phone
  • Bank Transfers

The UIGEA prohibits gambling businesses from knowingly accepting payments in connection with the participation of another person in a bet or wager that involves the use of the Internet and that is unlawful under any federal or state law. (2)


Since the adoption of the Unlawful Internet Gambling Enforcement Act (UIGEA) in 2006, payment methods for US players have become rather limited resulting in some online casinos rejecting payments via credit/debit cards like American Express, Visa and MasterCard but there are alternative options available and players just need to check the methods prior to depositing.

Blacklisted Casinos in the United States

It’s sad to say but some online casinos are not as player-friendly as we’d like. In fact, they’re downright unfriendly, unsafe and insecure. We know this as they may offer unfair bonus terms and conditions, take months to pay out winnings or not pay out at all. 

These unsavory sites make it straight to the top of our blacklisted casino list:

Cool Cat Casino
  • Unfair wagering
  • Scam reports
  • Support unavailable
Planet 7 Casino BLACKLISTED
Planet 7 Casino
  • Unresponsive to queries
  • Poor customer support
  • Unpaid winnings
Grand Prive Casino BLACKLISTED
Grand Prive Casino
  • Vague licensing details
  • Unresponsive support

Gambling Laws in the United States

Gambling laws in the US are complex and rather a ‘grey’ area for all concerned. The laws work on both a federal and state level, technically there’s no defined federal law against online gambling, however, individual states are allowed to implement their own regulations.

Fortunately, where states do impose gambling laws, they target online operators rather than the players, for instance, the adoption of the UIGEA made it illegal for businesses and financial institutions to process payments from unlawful online gambling. 

Considering the popularity of land-based casinos across the US it is strange to discover an inconsistent framework, however, times are evolving and gradually more states are moving to legalize online gambling.
