Best Online Casinos

You can find many operators that offer sportsbooks, DFS, and social casinos, but when it comes to online casinos finding them can take a bit more of research since they are only legal in 4 states.

I have gathered a list of my favorite online casinos, featuring a small description of them, their bonus offer, and game libraries!

Bet365: Pros & Cons

Are Online Casinos Legal in the US

Online casinos are heavily restricted across the US, although you might find some states that allow online sportsbooks, when it comes to online casinos, the list gets shorter.

There are only 4 US states with legal online casinos, those being Michigan, New Jersey, West Virginia, and Pennsylvania.

You can find social casinos across the rest of the US allowing players to get a similar experience to classic online casinos.

While traditional online casinos are only legal in a handful of states, Americans in most other regions can still enjoy casino-style games through sweepstakes and social casinos. These sites operate under sweepstakes law rather than gambling regulations, making them legal in most US states (Washington State, Maryland and Michigan are exceptions).

Instead of betting real money directly on games, players use virtual currencies in a dual-currency system. The primary currency (often called Gold Coins or similar) is used purely for entertainment and has no real-world value.

The secondary currency (commonly known as Sweeps Coins, Sweepstakes Coins, or similar names) can be redeemed for cash prizes or gift cards after meeting certain requirements. Players can acquire these virtual currencies through purchases of gold coins (with sweeps coins one given as a "free" bonus), daily login bonuses, sweeps casino no deposit bonuses, social media contests etc.

The sweepstakes games available typically mirror what you'd find at traditional online casinos, including slots, table games, and sometimes even live dealer options. As with regular casinos, there are fresh games and brand new sweepstakes casinos popping our all the time, so you'll always have something interesting to try out.

Here are some of the most popular sweeps casinos we feature on our site, but if you want to learn more, you can always check our full list of all sweepstakes casino in the US.

Operator checklist: 5 things we look for when rating top online casinos

Legal status and safety are priority number one
PromoGuy only recommends online casinos that are legal and regulated according to the State they are operating in. This means that one online operator may be available in different states, and it should thus meet the legal and regulatory requirements of each US state’s regulatory body to get a thumbs up from us. There are a lot of risks for you as a customer if gambling at a non-regulated and unlicensed casino, which is why we make sure we give you all the facts in this regard. Another crucial component we look at is the measures the online casino took to protect interactions with customers that are financially oriented like deposits and withdrawals. We look for site encryption and other measures put in place to keep customers and all information provided to the online casino private and encrypted.
Game and software quality
Being experienced reviewers of casino games and much more, we know what quality games look like and which developers offer the top options. This is another crucial step in our rating journey where we really dig in and look at the game quality online casinos put out there. Superior game quality doesn’t only enhance the player’s experience, but also increases the possibility of returns, especially when it comes to slots. Game quality is always featured in our online casino reviews, so make sure to take a look.
Payment method variety
What do you think of an online casino that offers one or two payment methods versus one that offers a variety to suit every online gambler’s preferences? If there is one thing customers can be picky about, it’s how to make deposits online, and we don’t blame them. Offering a choice of safe and secure payment options in both the deposit and withdrawal sections are points of interest to us as it makes online casinos more accessible and customer-friendly. That being said, nobody wants to wait for eons for their winnings to pay out or for their deposit to reflect, so this is also something we look at during a PromoGuy casino review.
Game options and variety
The best online casino sites are synonymous with choice. And, most importantly, choices should include the games offered to customers. We’re always on the lookout for a massive slots section with stacks of different games, a comprehensive table games section where you’ll be spoilt for choice, and a live casino section where you can access your favorite games and more in a live setting. Quality and choice go hand-in-hand, so we still expect top-quality casino gaming options if we encounter variety.
Customer support
A token of respect for its customers, we salute the operator who offers quality and courteous customer support. There are many different ways to offer customer support; however, as tech becomes more and more instant, the option we look for in the ideal operator is a live chat option with a quick response. In many cases, customer support is offered in different forms like an added FAQ section for customers and an email option, so looking at the big picture and feasibility of the support options. So, in the end, it needs to work, no matter how technologically impressive it is. You’ll find these important details in every PromoGuy casino review.

Finding the right operator for you - some pro starter tips

Now that you know where you can find the top online casino reviews and get access to inside info about the top online casinos, where do you start?

To find the perfect online casino for you, you also need to look at you.

Most top casinos operate to accommodate online gamblers with diverse needs, but to identify the gambling needs that make you tick, let’s ask some reflective questions:

When is your favorite online gambling time? When you typically like to log in can play a role regarding your access to certain sections of the casino, even the best online casino sites. If you’re a live casino player, then you may have to look at when the live casino is available at different top online casinos and do a little online casino comparison in this regard.

What do you like to play? While you’ll find several casinos that get top online casino ratings, their game repertoire will always be a bit different. If you’re new to the scene, you may want to look for an operator that offers variety in every department, while if you’re interested in slots specifically, you may want to look for a massive slots section with quality games. Some operators even offer free slots that pay real money with no deposit.

Where do you play? Do you like to play on the go, or do you prefer to sit behind your PC or laptop? If you’re an app person, you need an online casino with a rockin’ app. If it makes no difference, you can put this option on the back burner.

There may be other questions completely unique to you.

These are examples you can use as starter points to find out what your ideal online casino would look like so our reviews can help you find it!

Play hard with our 5 ultimate tips for using the best online casino sites

The choice is still yours, so keep on looking around if you want to

Even after you’ve chosen an operator that best fits your wants and needs by looking at our quality online casino reviews, you can still shop around as no online casino is perfect.

You may come across another casino that offers some regular promos you’d like to try out. There’s no monogamy here, so shop and go for the best deals, even if they are at another casino than your first choice.

You can find really good $20 minimum deposit casinos where for $20 you can get really good deals like extra free spins!

Make sure you and the T’s & C’s have an agreement

With every promotion, free spins offer, and just gambling in general, you’re going to find yourself face-to-face with a set of terms and conditions.

Knowing the requirements or House Rules can help you develop smart strategies and prevent you from losing out on opportunities offered by the operator just because you’re not familiar with the T’s & C’s.

When in doubt, you can find all the most important details you need to know about in our reviews covering top online casinos.

Check for worthwhile games by looking at the RTP rates

RTP rates are usually tied to slot games and show you how often you’ll get returns when playing a specific game in the long run.

Ideally, you need to look for games with RTP rates that are 95% or higher. If you find a slot with an RTP rate of above 100%, which is highly unlikely, it means that this slot will actually cause the casino to make a loss instead of a profit, which is a great example of how RTP works.

You’ll find that games with the highest RTP rates are usually developed by top gaming development companies like Microgaming, NetENT, and others.

You can find all the details about worthwhile games in our PromoGuy online casino review section to help you choose games that have shown to give back.

Consider learning about or developing targeted betting strategies

Casinos would like you to believe that gambling is a one hundred percent game of chance. While Lady Luck is ever-present, it’s possible to bamboozle her a bit and create some luck of your own.

Promoguy.us is the ideal platform for you to learn about strategic betting and how you can finetune your approach to online gambling.

In other words, we’ve got the content for you if you want to know how to make money gambling online in the US.

If you’ve ever considered looking at this angle before, prepare to be introduced to a whole new world of online betting.

Join the rewards/loyalty program of the best online casinos

This actually depends on how often you spend time on your choice from the top online casinos. If you’re a regular, then taking advantage of an operator’s rewards program adds little (or even bigger) perks.

Most top online casinos have loyalty programs that you can enter into without any specific requirements.

Some even enter you automatically to encourage you to visit the site on a regular basis.

The best casino websites will make sure you get back what you put in if you’re a regular using the rewards program they offer.
