Which States Offer Legal Online Casinos?

  • Delaware: While many people don’t know this, Delaware was actually the first state to legalize online gambling in any form, back in 2012. Each land based casino in the state was given a license to operate an online casino, which they have been doing for a decade now.
  • New Jersey: The state of New Jersey was the next state to legalize online gambling in 2013, following the Supreme Court’s decision to repeal the federal laws that didn’t allow online gambling operators to work within the US. Bill A2578 historically regulated online casinos and poker sites within the NJ borders.
  • Pennsylvania: The Pennsylvania Gaming Control Board (PGCB) started accepting applications for legal online casinos in summer 2018. Since then, a number of casino sites have fully launched in PA, all in accordance with an earlier approval of online gambling that was issued on October 30, 2017.
  • West Virginia: In March 2019, West Virginia joined the growing trend of states that allow online gambling. First online casinos were launched in 2020, following the process of vetting and licensing for the prospective casino operators.
  • Michigan: Online casinos only became a reality in Michigan in December 2019, when Gov. Gretchen Whitmer signed the gambling expansion package into law and made Wolverine State a new safe haven for online casino operators.
  • Connecticut: The state of Connecticut was a late comer to the online gambling ball, as the state only legalized it in October 2021. The first legal online casinos are now launching in CT, with 2022 being the year when online gambling will fully launch in the state.

Best US Online Casinos

With online casinos becoming bigger in the US every year, and new states issuing laws to allow them within their borders, we are seeing several major operators launch in as many markets as they can. These are the top US online casinos you should be on the lookout for:

BetMGM Casino

A major online casino operator available in all regulated US markets, BetMGM Casino is the current industry leader. With a massive selection of popular casino games, valuable online casino deposit bonus, and more, the operator offers the finest online gambling experience in the US.

Stars Casino

Operated by The Stars Group (part of Flutter Entertainment), the owners of the popular online poker site PokerStars, Stars Casino is legal in NJ, PA, MI, and looking to expand beyond. A valuable online casino no deposit bonus of $50 is available to newcomers, along with many other perks and reasons to play here.

DraftKings Casino

DFS fans are all familiar with DraftKings, but the operator now also runs online casinos in major US gambling markets. Today, DraftKings Casino is one of the best casino platforms out there, with a special focus on servicing players who prefer mobile gaming.

BetRivers Casino

Available as a sportsbook in a great number of states, and as an online casino in four markets and growing, BetRivers is another major local operator that should not be overseen. BetRivers Casino is a serious contender in the US iGaming market and a site well-worth the visit for all players.

Borgata Online Casino

A major online casino operator in NJ and PA, Borgata Online Casino operates an entertaining and exciting iGaming platform that can contend with the best of them. Whether you are looking to play slots, live table games, or other casino games, Borgata Online Casino has your back.

Choosing an Online Casino Site

If you are a casino player looking for online casino apps in the US, there are quite a few things to consider. We always recommend playing only on legal online casino sites, but what does that mean exactly and what things should you be on the lookout for.

Here are a few main criteria we believe make a great online casino option for you:

  • Regulated in Your Market: The most important thing you should make sure of is that you are playing at an online casino that holds a license in your state. Every state has its own regulator that issues gaming licenses, and you must make sure you are playing at a casino with the appropriate license.
  • Games Portfolio: Different casino sites offer different games. While there is a lot of overlapping, we recommend going over the casino’s games and choosing the right site based on the games they offer and your personal preferences.
  • Bonuses & Promotions: Operators regularly provide players with incentives to play on their site instead of elsewhere. Look for online casino bonus codes, promotions, and rewards you can claim to boost the value of playing at a certain casino.

How to Get Started Playing Online Casino Games in the US

Getting started with US online casino apps is not too difficult, but there are certain steps you will have to go through. Here is a step-by-step guide to getting started with US-based online casinos:

  1. Pick Your Casino: First thing is first! You need to pick which online casino operator you want to join, and you can use the parameters we stated in the previous section, as well as our online casino reviews, to make up your mind on this.
  2. Sign Up: Once you have picked an operator, you will need to register a player account with them. The process takes a few minutes and requires you to provide the casino with some basic information on who you are.
  3. Confirm Your Identity: The casinos will ask you to confirm your email, phone number, and eventually identity as well, which will be done by sending copies of your personal documents. This is done for your protection and safety and is standard procedure all over the world.
  4. Get Your Casino App: Downloadable online casino apps are available from all major US online casinos, and you can get the appropriate one for your device from the operator’s website.
  5. Start Playing: Once you have created your account and downloaded the app, you can make your first deposit, claim your online casino deposit bonus, and start playing real money games with some extra cash in your balance.

How to Know an Online Casino is 100% Safe and Regulated

While legal online casinos are now available in the US, there are still many offshore sites that accept American business without the appropriate licenses. So how exactly can you know which sites are regulated and safe to play at? Here are a few major indicators to look out for that won’t let you down:

  • The Regulator’s Seal: These seals are more indicative and important than any other thing you can look for. iGaming regulators put their seals on the sites they license, and clicking this seal will take you to your state’s regulator website. If it does not, the seal is fake. If it does, you can check out the details of the license and be sure you are playing on a safe site.
  • Only Available in Some States: Online casino gaming is currently only legal in six states in total. If an online casino accepts business from other parts of the US, including the states that don’t allow iGaming, then you are looking at an offshore site that’s illegal in the US.
  • Locally Owned Business: While US online casinos are all parts of major international companies, they are all legal entities within the US. International companies that deal in the US all have US subsidiaries which run local sites, so be on the lookout for casino ownership.
  • US Casino Partnerships: To acquire a gaming license in any of the states that regulate iGaming, an operator must partner up with a live casino from the US. If you can’t find out who the live partner is to an online casino, chances are the site doesn’t have one and doesn’t have a license to operate in your state at all.
  • Live Customer Support: Like any good US company, US online casinos run customer support via telephone on most occasions. You should be able to contact your operator via phone during business hours and take care of any inquiry in short order.
  • Loyalty Rewards: Major US casinos offer lucrative and well-known loyalty reward programs. If you are playing at a regulated online casino, expect to be part of a VIP scheme that offers plenty of rewards for being active on the site.

Why Are Legal Online Casinos Better?

Legal online casinos have only been a reality in many US markets for a very short time, while players have been playing on illegal offshore platforms for years. So why exactly should you play at a legal casino and stop using any unlicensed platforms? Here are only a few of the important reasons for that, while many others exist as well.

  • Fair Casino Games: Perhaps the most important thing whenever you are gambling is that you are not being cheated. All games offered at regulated casinos are independently audited, while the same cannot be said for offshore casino platforms. If you want to be sure the game you are playing is fair, you need to play at a licensed casino.
  • Player Satisfaction in the Focus: Regulated online casinos focus on their players’ safety as a matter of good business. They try their best to keep players happy in order to get good press and word of mouth, as well as to keep away from any legal troubles. US online casinos focus on player safety above all else.
  • Funds Security: The number of schemes in which offshore casinos stole player funds is too high to count. US online casinos keep your funds 100% safe and segregated from their operating funds, meaning you have access to them on request, at any time.
  • Your Information Remains Private: While offshore casinos have no obligation to keep the personal information you share with them private, US online casino operators actually do. Any info you share with your legal operator will be held 100% private and safe at all times.
  • Play with Major Casinos: Operators like BetMGM, DraftKings, and BetRivers are well known US brands that have been around for a long time and have a great reputation. Ensure you are in good hands by playing with such brands.
  • Socially Useful Programs: The taxes that states collect from US casinos go towards important social programs such as education and healthcare. On the other hand, offshore casinos don’t pay any taxes in the US and any money they win from you goes towards their owners getting richer, and nothing more.

Extra Value – Bonuses and Promotions

Some of the best online casino no deposit bonuses, deposit bonuses, and other promotions can actually be received from legal US casino sites. If you want to play casino games, playing with a legal operator is a matter of value, as there is a lot to gain by playing in the right place.

Welcome Bonuses

Valuable online casino deposit bonuses can be received from every US casino operator. When signing up, players are presented with an opportunity to make their first deposit, which is usually doubled in value by the casino.

Claiming a welcome bonus will give you a significant starting boost, with extra money in your balance meaning you get to play higher and have a chance for a bigger win. While there are no guarantees, the welcome bonus will give you a better chance to win, with very little downside.

No Deposit Bonuses

Online casino no deposit bonuses are promotions offered by operators to players who simply sign up. Just registering an account with many US casino sites will give you a no deposit bonus worth anywhere between $10 and $50.

These bonuses are designed to let you try real money gaming without any risk at all. While you are not risking anything, you will be given a chance to cash out your winnings if you do end up in profit, so there is really no downside to taking these bonuses and trying your luck for free.

Loyalty Schemes

As previously mentioned, US online casinos all offer loyalty schemes, which reward players who keep coming back, as well as those who play exceptionally high-stakes.

If you enjoy playing slots or table games for a lot of money, or simply like to play for lower stakes every day, joining these loyalty schemes will give you some extra reason to keep coming back and play on the same site every time, as your perks and loyalty points keep racking up and your rewards only get bigger with time.

Online Casinos vs. Live Casinos – Which is Better?

With many live casinos available around the country, even in states where iGaming is not yet regulated, it makes sense to ask questions about the difference between live and online casinos. In truth, online casinos offer quite a few advantages, and here are a few of them:

  • Available Everywhere: Playing casino games live means going to an actual casino venue, which can often be many miles away from players’ homes, especially in some states. Online casinos offer instant entertainment anywhere, with action available around the clock.
  • Mobile Gaming: Playing on your mobile device is yet another advantage that has to do with availability. Not only can you play from anywhere, but all you need is your mobile phone or tablet to play any casino game you like.
  • More Games: Despite their best wishes, most live casinos can only offer a limited number of casino games, due to lack of space. Online casinos don’t suffer from this problem and can offer any number of games they choose, which they take full advantage of.
  • Any Stakes: Whether you want to play for just cents, or bet high-stakes, all options are open with online casinos in the US. The range of bets available in online casinos is way higher than you could find in a live casino, especially for table games.
  • Casino Bonuses: Whether through special online casino bonus codes or directly, online casinos offer plenty of bonuses to their players. Welcome bonuses and similar promotions are not available in live casinos, giving online another advantage.
  • Loyalty Schemes: While both live and online casinos offer loyalty schemes, the ones offered online are usually more attractive in terms of rewards and perks you can get, which translate into more cash and bonuses and fewer comps and perks you find in live casino venues.

History of Online Casinos in the US

Online casinos were not always legal in the US, and their legal history is somewhat short and interesting. Here are the main things you need to know about how online casinos came to American and how we got to this point in time in terms of regulation and spread of iGaming:

  • First Online Casinos: The first online casino sites launched back in the late 1990s internationally. These sites offered their services without discrimination to anyone, before countries began regulating online gambling and first gaming licenses appeared.
  • UIGEA Passes: In 2006, the US Congress passed the Unlawful Internet Gambling Enforcement Act (UIGEA), which restricted all forms of online gambling within the US. Under the act, financial institutions in the US were prohibited from processing gambling transactions, making online gambling practically impossible in the country.
  • First Regulation: Despite the UIGEA and pressure, the state of Delaware decided to regulate online gambling on state level in 2012, followed by New Jersey in 2013. This began the regulation process in the US, with other states following in their footsteps.
  • Regulation Expands: After a few years of silence, new states began to adopt Bills regulating online gambling. Pennsylvania, Michigan, West Virginia, and Connecticut all joined, with other states currently working on their own regulations.
  • What’s Next: With more and more states adopting legal online gambling, and sports betting available in half the country, it is only a matter of time before online casino games are available in a good chunk of the US completely legally.


Are online casinos legal in the US?

Online casinos are legal in some parts of the US, namely Delaware, New Jersey, Pennsylvania, Michigan, West Virginia, and Connecticut. In these states, licensed operators provide legal online casino games. In all other parts of the US, it is not yet possible to play casino games on the internet legally.

Who regulates online casinos in the US?

Each of the states in which online casinos are legal has a regulatory body of its own. In order for a casino to provide services in a certain state, it must obtain the appropriate gaming license from the regulator in that state.

How do I know if a casino is really licensed?

The easiest way to find out if an online casino is regulated in your state is to visit their website and check for regulator seals. If the operator is regulated, they will have a seal on their website, which links back to the regulator’s website. If not, such a seal will not appear. In some extreme cases, the seal may be faked, but you can easily check if the seal is real by visiting your state’s gaming regulator and checking their list of regulated entities.

How can I sign up with a regulated online casino?

If your state offers legal online casino gaming, you will be able to set up an account and play real money games within minutes. Find out which operators are regulated in your state, visit their websites, and start up the registration process where you will provide your personal details and create a unique login name and password to play with.
