Currently, more states are allowing sports betting than online poker and casinos. Most likely this is because online casinos have taken a while to catch up with the law – even though the first legal online casino started more than a decade ago, only seven states have regulated online casinos: 

• Connecticut: The Nutmeg State legalized USA online casinos in 2021 under the same House Bill that legalized online sports betting, poker, and Daily Fantasy Sports. Any player over 21 can choose between two legal casino sites regulated by the Connecticut Department of Consumer Protection.
• Delaware: In 2013, Delaware was one of the first states to offer players a legitimately safe online casino. The Delaware State Lottery is allowed to provide online casino games.
• Michigan: In 2019, Michigan lawmakers passed the Lawful Internet Gambling Act, allowing online gambling and casinos to be legal. However, it was another two years before the first online casino launched in the state. A few years later, there are no more than 15 legal real money online casinos in MI.
• New Jersey: New Jersey is and always has been one of the homes of legal gambling in the US. The legal online gambling bill was passed in 2013, and there are currently more than 20 online casinos operating in New Jersey.
• Pennsylvania: Pennsylvania began permitting online casinos to operate legally in 2019, nearly a year after the governor signed HB271. Influenced somewhat by the neighboring New Jersey, PA residents have the luxury of more than 20 safe and secure online casinos.
• Rhode Island: One of the newest states to allow legal online casinos, Rhode Island’s governor signed the bill in June 2023. Like Delaware, the State Lottery is allowed to operate online gaming sites.
• West Virginia: WV also runs its online gaming operations through the State Lottery. The first online sites were launched in 2020, and four sites are currently running.

The top casino games in the US draw hundreds of thousands of players nationwide daily. Staple games like roulette, craps, and poker will always live at the top of most gamblers’ favorites. While there are plenty of games to try out, the top games are at the top for a reason and are usually a good starting point for new bettors looking to get their feet wet.

Let’s look at the most popular online casino USA games: 

Online Slots

Online slots quickly became one of the most popular online casino games in the US, offering one of the fastest ways to win big with just one button push.

Online Poker

Online Poker was one of the earliest online casino games in the country. It offers various card games with head-to-head action rather than taking on the house.

Online Blackjack

Online Blackjack is a fast-paced card game with short hands and high stakes. You don’t need to hit 21; just beat the dealer’s hand to win.

Online Roulette

The dealer of Online Roulette drops the ball upon a spinning wheel as players wager on which number it will land on.

Online Sic Bo

As online dice games surge in popularity, none rise more quickly than Sic Bo. We’ll let you decide if there’s any skill to throwing the dice.

Video Poker

Online slots and online poker meet in Video Poker. Players aim to make the best 5-card Poker hand, with the option to discard in exchange for cards off the top of the deck.

When you play at online casinos in the USA, you’ll notice that many of the bonus offers and promotions are recurring. Popular offers such as welcome bonuses, cashback bonuses, and more can be found at most legal gambling sites across the US. We put together a list of the most common promo types, and a few special ones we particularly enjoy.

Bonus Type	Description
Welcome Bonus	Earn free bets, spins, and more for various games when you sign up for a new account with an online casino US.
Deposit Match	Deposit money into your account and the casino USA online will match that amount to a specified amount.
Free Spins	Collect free spins to earn money and prizes without spending a dollar.
Cashback	This deal returns players a percentage of their losses should they fail to win a bet.

Moving money between your various USA online casino accounts should be simple. Once you’ve added a  payment method at your chosen casino, using it is usually a matter of a click or two. It’s important to have flexibility with the varying payment methods offered at online casinos in America by keeping your options open. 

For example, if you prefer not to connect your online bank account to your online USA casino account, you’ll need to sign up for PayPal or the other popular methods widely offered. 

This table shows the most popular deposit and withdrawal options and their processing times. You’ll probably notice that there are usually more depositing options than withdrawal methods at most US real-money online casinos.

Online casinos in the US come in all shapes and sizes, which can be overwhelming when you’re trying to sift through the hundreds of options to discover your preferences. We’ve compiled a list of the most popular types of American online casinos, and what sets them apart.

Sweepstakes Casinos

Sweepstakes casinos have emerged due to strict US gambling regulations. In states where real-money casinos aren't allowed, players can register for social casinos, some offering opportunities to win cash through sweepstakes.

New Casinos

Many new online casinos launch regularly in the US, each offering attractive bonuses and unique features to stand out. We review these newcomers to ensure you get the best options.

Mobile Casinos

Mobile casinos are growing in popularity, as more players enjoy accessing their favorite games on the go. The top casinos are mobile-friendly, and we help you find the best options for playing on mobile.

Fast Payout Casinos

After winning, you want quick access to your funds. Many players look for casinos offering fast or same-day withdrawals, and we highlight the best ones.

Best Payout Casinos

Online casino games have different payout rates. To boost your chances of winning, look for casinos with the highest payout rates, which we feature in our list.

VIP Casinos

VIP casinos offer exclusive rewards and multi-tiered programs for their loyal players. Some go above and beyond, offering luxury gifts or even European trips for their top players.

Knowing what makes a good online casino is important before choosing one. Here are the key factors we consider when ranking the top US online casinos.

Mobile App

Many players prefer gambling on their phones. A good, easy-to-use mobile app can make a big difference for casinos that want to attract players.

Gaming Variety

A casino with many game options keeps players interested. Top casinos offer hundreds or even thousands of games, giving players plenty of choices.

Secure Deposit & Withdrawal Options

It's crucial to have safe ways to deposit and withdraw money. All casinos we recommend are licensed by state gaming boards, ensuring your money is protected. If a casino doesn’t pay you, you can take legal action.

Fast Withdrawals

Players want to access their winnings quickly. Check that the casino offers fast payment methods before signing up.

Reliable Customer Support 24/7

Even the best casinos make mistakes, but they should fix them quickly. Good casinos offer round-the-clock support to help players resolve issues.

Consistent Promotions & Bonuses

Casinos use bonuses to attract and keep players. A solid welcome bonus helps players feel more connected and valued by the casino.

Winning big is great, but only if your money is safe. Here's how to tell if an online casino is secure and legitimate:

Licensing by a Reputable Authority

A recognized authority should license a trustworthy casino. Avoid casinos that aren’t properly licensed, as they may not be reliable.

Secure Socket Layer (SSL) Encryption

Look for SSL encryption, which keeps your personal and financial data safe. Don't sign up if a casino doesn’t use SSL encryption for transactions. You can usually see a padlock icon in your browser during deposits or withdrawals to confirm SSL protection.

Promotes Responsible Gambling

A good casino encourages responsible gambling and provides tools to help players manage their gambling habits.

Plenty of Positive Player Reviews

Check player reviews before signing up. A trustworthy casino should have plenty of positive feedback from real users. If most reviews are negative, it's best to look elsewhere.

When choosing an online casino, knowing which ones to steer clear of is just as important. Here are some red flags to watch out for:

1. Unlicensed Casinos: If you can’t confirm that a casino is licensed by a legitimate regulatory authority in your state, avoid it. Playing on unregulated sites means any legal entity doesn’t protect your money.
2. Recurring Payment Issues: If a casino consistently fails to pay out your winnings or takes too long, it's a red flag. If the problem persists, contact your state’s gaming control board for assistance.
3. False Marketing: Be cautious of casinos that send misleading marketing materials with offers that seem too good to be true. If they fail to honor their promotions, report them to your state’s gaming control board.
4. Poor Customer Support: Good customer support is crucial. Avoid casinos with limited or no support, as top US casinos offer accessible 24/7 customer service to help resolve any issues.

Irresponsible gambling habits create a slippery slope to addiction and severe life consequences. If you are finding it difficult to control your gambling while playing in a USA casino online, there are a myriad of ways to receive help. Each state will offer various hotline numbers to guide those seeking aid with their gambling.

At Casino.com, we strive to provide convenient access to tools that prevent such issues. Should you have any concerns about yourself or those in your surroundings, here are valuable resources that can be of assistance when playing in online casinos:
