Online casinos in the US offer players a fantastic entertainment opportunity. However, the legislative landscape can make things a little confusing, as gambling for real money is not legal everywhere. In addition, even in states where gambling is legal, not all forms of gambling are allowed. 

  • Casino gambling for real money is currently restricted to seven states (although it is now legal in eight, one has not yet gone live). 
  • Poker is different from online casino games (even though it can be played in casinos).
  • Sports betting is different again!
  • Sweepstakes casinos that use virtual currency are not regulated the same way, but they have now been outlawed in several states.
  • Social casinos are available across the country (but real money and prizes cannot be won).

So, when we say which casinos are hot, we mean hot good rather than hot illegal (although you want to make sure that you are playing at legal casinos. With the US online casino market on track to reach USD9 billion by 2032, there are plenty of operators vying for customer attention. Despite being a potentially massive market, it is highly fragmented, leading several international operators to withdraw. At the same time, legacy sports betting brands like FanDuel and DraftKings have sidestepped and developed strong casino offerings. Legacy land-based brands are also strong in the market and mobile-first newcomers have offer some great games and odds. 

 It can be quite a tricky market to navigate, especially if you are moving between states. Many visitors to Las Vegas, for example, are surprised to learn that, despite being the self-proclaimed global capital of the entertainment industry, online casino gambling is strictly forbidden (but online poker is allowed). Therefore, for those trying to work out where to play and what to look out for, a little expert advice can be useful.

Fortunately, expert help is relatively easy to find, but it is important to ensure that it is independent and unbiased. This is where Casino.org really comes into its own. The site has been in operation for over three decades, and its experts uncover the best gambling sites to help players avoid risks. They only rate and review sites that have all the correct licenses in place and focus on finding fun and entertaining sites and games that offer the best value for money. By the time they make recommendations, the sites have been thoroughly stress-tested.

US players need to be aware that not everyone making recommendations has the experience of Casino.org. Influencers, for example, might wax lyrical about a particular game, stream, or platform, but have they actually put the site through its paces, or are they just a paid mouthpiece? It is important that readers can differentiate between genuine content reviewers and paid brand advocates. A great independent site like Casino.org offers data-driven, analytical reviews. Sites that review online casinos thoroughly are increasingly rare in today's highly competitive market. Before you take advice at face value, it is worth questioning what it is based on. Casino.org has a twenty-five-step review process – it is about the toughest and most trusted in the business. Here is a summary of what they are looking for and how they go about stress testing the sites.

It all starts behind the scenes, on what might be regarded as the boring part of the research. Expert reviewers want to know that sites are properly licensed in the states where they operate. Real-money casino gaming sites are legal only in New Jersey, Pennsylvania, Connecticut, Delaware, Rhode Island, Michigan, and West Virginia. Maine has recently legalized them, but the market is not operational. If you are offered real-money gaming services outside these US jurisdictions, the sites are operating offshore and in the grey market.

Security is also important – have the sites got the most up-to-date security protocols in place (always check for HTTPS in the site's URL)? The S stands for secure. In addition, great sites are fair and offer players reasonable chances of winning. While everyone knows the house always wins, for it to be fun, the random number generators behind the games need to offer fair odds and not be rigged or unreliable. Great sites have their games verified by external agencies like eCOGRA.

The best online casinos team up with reputable payment and software providers. There should be plenty of recognizable named payment partners like PayPal, Visa, Skrill, and Neteller, and games from providers like NetEnt and Microgaming. Sites might have games that are exclusive to their site, but they should still be developed by a recognized, licensed developer. Don't be fooled – if payment options don't look secure, it's a red flag, and you could be playing on a site that is hot for all the wrong reasons.

While everyone hopes for a great player experience, we do need to consider what happens when something goes wrong. How accessible are customer services and by what means? 24/7 access is best, but if it is just an AI chatbot that sends you round in seemingly infinite loops, it will not make for a great gaming session. The experts at Casino.org create accounts and test out customer services just to be sure.

Once all those background checks are in place, it is time to move on to the fun side of checking out the online casino. While this is where most players start looking, great reviewers only get to this part once they are happy everything else is in place. The hottest online casinos have huge game libraries and might offer thousands of slot titles. They will also have a fantastic selection of casino classics, including roulette, baccarat, and pontoon. 

You should be able to find exactly the games you want to play, whether as video simulations or as live dealer versions. Remember, this is entertainment, and you want to be entertained. The games should load without glitching and run smoothly. As more and more of us play on our smartphones, the games need to be as great on the small screen as on the large one. Keep an eye out for great bonuses too. All the operators are vying for attention in a busy market, and you can find fantastic sign-up, welcome, and loyalty bonuses. However, do not forget to check out the small print and wagering requirements – some dealers look great on the surface but have onerous conditions making them less attractive in reality. 

What is hot and what is not comes down to personal choice, but the basics should be rock-solid.
