How We Rank Real Money Online Casinos

To help you find the best online casinos for real money, we evaluate every site and what they offer. Here are some of the main points we take into consideration when testing casino online sites, ensuring a safe, reliable, and transparent gambling experience:

• Payout Rates: It’s important to know which casinos stock plenty of high RTP (return to player) games, putting more money staked by players back into the pockets of users.
• License and Security: Offshore online casinos need to be full licensed, which ensures they are 100% safe and legit. We ensure they are safe online casinos that incorporate the latest security technology, use RNG software for fairness, and offer games from reliable providers.
• Casino Games: The best online casinos for real money need to provide a good variety of game types that accommodate all players. The interface needs to be easy to navigate, responsive, and make it easy to find games.
• Casino Bonuses: The best paying online casinos have excellent bonuses. We review the bonus amounts, what you get, and the terms and conditions. The best casino bonuses strive to deliver bigger bonuses with fair terms and conditions.
• Payment Methods: We evaluate the variety of payment methods, minimum deposits, maximum withdrawals, speed, and how transparent the casino is when it comes to verification and withdrawal processes.
• Mobile Gaming: Mobile casinos are preferred by more than 80% of gamblers in America. Therefore, we ensure the site offers an easy-to-use mobile layout or offer casino apps that offers fast access to your favorite games.

Are Real Money Online Casinos Legal in the USA?

In states where real money gambling online is not regulated, online casinos for real money fall into a legal grey area.

It’s worth remembering that online casinos are not illegal at the federal level, and the law allows individual states to regulate various forms of gambling. It’s important to understand that gambling at an online casino in states that do not regulate casinos is not illegal.

If a state doesn’t allow online gambling, it may require payment processors to block transactions to online casino sites. This is why many players in America use crypto or e-Wallets, which is a simple solution that also has the added advantage of increasing your anonymity.

What Are the Best Payout Online Casinos?

The highest paying online casinos have higher overall payout percentages. They achieve this by offering game providers with higher payout rates, which increases your chances of winning.

To find the highest payout casinos, it’s best to focus on the game developers available. While many providers have high RTP games, it’s best to focus on the overall payout rate, which ensures an overall higher payout rate.

Game Providers with the Highest Payout Percentages

The industry standard payout percentage is 96%, meaning the casino has a 4% advantage, which is also known as the house edge. Some games, such as progressive jackpot slots, have lower RTPs as a portion of your wager is contributed towards the jackpot. Other games, such as high RTP slots, exceed expectations with percentages well above the standard.

Most game providers have overall payout percentages of around 96%, which indicates a good mix of gaming fairness. Some providers also exceed the standard, but it’s important to remember that table games tend to have the highest RTPs.

Therefore, to find casinos with the best payout rates, we recommend choosing casinos with top-rated game providers and playing their highest RTP games.

Provider	Average RTP	Highest RTP Game
Evolution (Live tables)	97%	Blackjack (99.3%)
NetEnt	96.5%	Mega Joker (99%)
Pragmatic Play	96%	The Catfather (98.1%)
Red Tiger Gaming	96%	Rainbow Jackpots (97.75%)
Big Time Gaming	96.3%	White Rabbit Megaways (97.72%)

Bonuses at the Best Online Casinos for Real Money

Bonuses at online casinos increase your account balance, allowing you to play more games, claim cashbacks, loyalty rewards, and more.

Not all casino offers allow you to play any games, and some have better terms and conditions than others, which is why we recommend comparing offers, terms and conditions, and what the bonus adds to your gaming experience. But to do that, you need to have a basic understanding of what casinos offer and what they mean.

Here are the most popular promos, what they do, and a tip to help you choose. At the end of the section, we’ve also included a breakdown of the terms and conditions.

Welcome Bonus – Biggest Reward with Your First Deposit

An online casino offers a welcome bonus when you join and make your first deposit. It’s usually the biggest and most attractive offer, adding free bonus money and possibly free spins to your account, simply because you joined and made a deposit.

Reload Bonus – Bonus Cash and Free Spins with Future Deposits

When you reload your account with another deposit, many American online casinos will reward you with another bonus. It’s usually smaller than the welcome offer, but still a great addition since you can get free spins and free bonus cash.

Cashback – Insurance for Unlucky Weeks

Think of a casino cashback bonus as insurance; it only activates when you’re having an unlucky week or month and rewards a percentage of your losses back, usually in real money without wagering requirements.

Free Spins Bonus – Play Real Money Slots to Win Bonus Cash

Free spins are brilliant since you get to play real money slots and keep what you win as bonus money. These are incredibly popular since even those who play table games can unlock bonus cash with slots and use the extra cash towards their favorite tables.

Loyalty Rewards – Additional Perks and Benefits to Enjoy

Loyalty rewards aim to keep you coming back and make more deposits by offering additional perks, bonus offers, and benefits you can’t get anywhere else. There are loads of unique reward programs, giving you lots of choices to match your gambling needs.

Understanding Bonus Terms and Conditions

Online casinos with generous bonuses are exciting, but it’s important to understand how the bonus works. You’ll find all the required details in the terms and conditions, which would usually include the following points. Let’s explain how they work:

• Wagering Requirements: Wagering requirements appear as a multiplier in the terms and conditions. It represents how many times you need to wager the bonus amount to turn it into real money.
• Game Contributions: Some games contribute a higher percentage of the wager amount than others. Slots usually contribute 100% of the wagering amount towards wagering, while table games range from 0% up to 50%.
• Maximum Bets: Betting limits indicate the maximum amount of a bet that can contribute towards wagering requirements. You can be higher, but the amount above the limit will not count towards wagering.
• Game Exclusions: Some games are excluded from contributing towards wagering requirements. You can still play them, but they will not help you complete wagering. This includes jackpot slots and possibly some other games, depending on the casino.

Best Casino Games for Real Money to Play in America

Online casinos for real money offer 200 to 10,000 games, each with its own theme, features, and betting options. Whether you’re new or an experienced gambler, knowing the types of games and the best titles in each category is a clear advantage.

Let’s look at the most popular categories you’ll find at top-rated online casinos, why players like them, and how to choose the best titles to try:

Online Slots – Games of Chance with Huge Payout Potential

Real money slots occupy the largest portion of any online casino, and it’s the most popular section due to its diverse range of game themes, special features, unique mechanics, and substantial payouts.

Choosing the right slots comes down to RTP and the volatility range that suits you. Ensure the RTP is at least 95% (preferably above 96%). Volatility levels depend on your risk level; low volatility is low risk with smaller payouts often, while high volatility is high risk with massive payouts that don’t occur often.

Online Roulette – A Strategist’s Favorite

Online Roulette is one of the world’s most famous table games, offering a variety of betting options and generous payouts. House edges tend to be on the lower side, especially when you play French Roulette with the La Partage rule that refunds half your even money bets when zero is the winning number.

At real money online casinos and the best Roulette apps, you’ll also find a variety of unique online-exclusive game designs, from European Roulette with special side bets to Double Ball Roulette. The best way to find the games that match your needs is to try them in demo mode, which is available at top casino sites.

Online Blackjack – An Even Money Betting System Favorite

Online gambling sites offer a huge variety of Blackjack games with unique betting options, side bets, additional payouts, and more. Most Blackjack games are impressive with payout percentages well over 97%, but if you’re looking for the highest possible payout rates, choose single-deck Blackjack, which has a return to player well over 99%.

To get the most out of Blackjack, a betting strategy is required, and depending on your experience level, you might also need a Blackjack chart that gives you some guidance as to what the next best move would be.

Online Poker – Most Popular Card Table Game

Poker at online casinos for real money is played against the house instead of other players, and you’ll find a variety of unique games. Most feature unique betting options and side bets, and you can expect unique game rules.

Low house edges are common, but as with other table games, a good strategy is key. We also highly recommend testing new Poker games in the demo mode, which you can do at most top-rated online casinos for real money. While popular games such as Omaha and Texas Hold’em are a go-to, we also recommend trying online exclusives such as Three Card Poker and Pai Gow.

Live Casino Games – Unique and the Most Realistic

Live dealer casino games apply to all game categories as providers such as Pragmatic Play and Evolution continue to push the limits of what’s possible. From standard table games to thrilling game styles with unique rules such as Lightning Roulette, there’s something for everyone to enjoy.

Live casino titles are not available in demo modes, but you can use low betting options from as little as $0.01 per round while you get to know the game. Of course, limits reach massive amounts, ensuring that strategists can use their favorite betting systems.

Another great advantage of live play is game shows. You can choose from strategy, skill-based, and chance games. These have presenters that guide you through the action and various bonus rounds that add a unique layer of excitement.

Best Paying Online Casino Games

The best paying online casino games have higher payout percentages, or return to player (RTP) percentages that indicate a higher chance of winning. While it’s important to understand these percentages are calculated over millions of spins and might not have a direct improvement on your winnings, they are the best games to play at online casinos.

Usually, the highest paying casino games are table games, but to achieve the best results, you’ll need to use a strategy or betting system. For players who want easy gaming sessions on games of chance, such as slots, we recommend the following titles:

Game Name	Return to Player (RTP)	Provider
Mega Joker	99.00%	NetEnt
Jackpot Jester Wild Nudge	99.00%	NextGen
Megaways Jack	99.00%	Red Tiger Gaming
1429 Uncharted Seas	98.60%	Thunderstruck
Jokerizer	98.70%	Yggdrasil

Other Casino Games – Unique Opportunities and Betting Options

You can browse through the large game selections at top-rated online casinos in America and find a seemingly endless selection of other games to play. From crash games such as Aviator to other table games like online Craps, you’ll find loads of games to make the most of every gaming session.

Some real money casinos will have a wider variety of other games, including scratch cards, fishing games, and video poker. When choosing the best casinos, ensure they offer the games you want; the libraries can differ depending on the casino and its audience.

Payment Methods at the Best Payout Online Casinos

You can choose from a variety of payment methods for deposits, withdrawals, and claiming bonuses. However, it’s important to choose methods that offer excellent security and easy transactions.

While bank transfers and credit cards might get blocked by the payment processor due to the current US law, there are other methods that provide lower fees, faster withdrawals, and better security.

Here are the most recommended methods to transact with the best online casinos, starting with the fastest and most recommended:

Crypto – Fastest, Most Secure, and Easiest

Cryptocurrencies such as Bitcoin and Ethereum are preferred by most gamblers for their speed, anonymity, low fees, and most top-rated online casinos for real money accept them.

Since banks and payment processors might block credit card and bank transfers going to casinos, gamblers in America use these payment methods to purchase crypto. You can either register and use your own crypto wallet (recommended) or buy crypto directly from the casino.

If you already have a wallet and funds, you can choose any of the crypto online casinos, register your account, and make your first deposit to claim the bonus and play casino real money games within minutes.

eWallets – Fast, Secure, but Expensive

eWallets are still incredibly popular at the best online casinos that payout faster, but they are known for higher fees.

Transactions tend to clear within hours, and you can choose from a variety of the best online casinos to make instant deposits, claim bonuses, and enjoy real money casino games.

We recommend reading the bonus terms and conditions, as some online casinos for real money might exclude eWallets such as Skrill and Neteller from claiming bonuses. It’s also possible that higher minimum withdrawals are required due to the higher fees.

Crypto is faster and has lower fees, but if you are not keen on the crypto route, eWallets are the best second choice.

Credit Cards – Convenient, but Not Ideal

Many credit card casinos have found ways to bypass American banks to make it possible for deposits and even withdrawals. However, banks are likely to block these transactions, especially in states where gambling is not regulated.

The casinos that do make these deposits and withdrawals possible will require a details verification process, and you’ll need to wait 5 to 7 business days for your withdrawal to reach your account.

Luckily, there is an alternative: you can use your credit/debit card to purchase crypto, or you can fund an eWallet for easier, safer, and faster deposits and withdrawals.

Bank Transfers – The Least Recommended

Many of the best paying online casinos don’t offer bank transfers anymore due to the higher fees and slot transactions. It’s also likely that you’ll need to deposit a lot more due to the fees, and secondly, most casino-related transactions will get blocked.

Withdrawals – if accepted – take up to 7 days to reflect, and you need to share all your banking details and personal information with the casino to process these payments.

As with credit cards, use bank transfers to fund your crypto or eWallet account. It’s far safer, faster, and you’ll get to play at any of the best online casinos for real money and claim bigger bonuses.

How to Choose the Best Payment Method – Key Takeaways

Online casinos in the US provide a wide range of payment methods; all that’s left to do is choose the one that suits your needs. Here are some pointers to help you find the right method:

• Payment Speeds: If you’re looking for fast withdrawal casinos that process payments within hours, crypto is by far the best. You can use your own wallet or purchase crypto with other payment methods at the casino.
• Low Deposits: You can choose from multiple $10 minimum deposit casinos that still give you a bonus. While many of these are crypto, you can also use other payment methods to activate the bonus.
• Security: If you’d like to keep your personal details 100% secure, we highly recommend crypto, eWallets, or Cash App casinos.

What is RTP, and How Does it Affect Your Chances of Winning?

Without getting technical or going into too much detail, RTP stands for Return to Player, and it’s always expressed as a percentage. It represents two things:

• Return to Player: The RTP is the theoretical payout you can expect. A higher percentage represents a better chance of winning.
• House Edge: If a slot has an RTP of 96%, the other 4% is the casino’s advantage (house edge). It’s what the casino expects to profit from the game.

Which Online Casino Games have the Highest Payout Percentages?

On average, table games have the highest payout rates, with some, such as Single Deck Blackjack and No Commission Baccarat, offering payouts of over 99%. However, you’ll need a solid strategy and betting system to achieve those results.

Online slots also impress with incredibly high payout rates, and since these are games of chance (you have no control over when it pays), you don’t need a strategy or betting system. However, you never know if the RTP is in your favor or not, and there’s no way of finding out.

Here are the top 10 highest payout games and their theoretical RTP percentages available at top-rated online casino sites:

High Payout Slot	Theoretical RTP %	Provider
Ugga Bugga	99.07%	Playtech
Goblin’s Cave	99.32%	Playtech
Mega Joker	99%	NetEnt
Book of 99	99%	Play’n Go
Jackpot 6000	98.9%	NetEnt
Blood Suckers	98%	NetEnt
Jokerizer	98%	Yggdrasil
1429 Uncharted Seas	98.6%	Thunderkick
Good Girl, Bad Girl	97.8%	Betsoft
White Rabbit Megaways	97.72%	Big Time Gaming

Expert Tips to Improve Your Chances of Winning at Online Casinos

To improve your chances of winning at online casinos, you can follow a set of rules that ensure you don’t make common mistakes.

While some players use strategies and betting systems, especially with table games, to increase their odds, these can be quite complicated. The following tips help improve your overall chances of winning without having to learn betting systems or strategies:

• Choose a Licensed Casino: Licensed online casinos must meet certain fairness rules and are only allowed to offer games that use RNG generators to ensure random results that meet the fairness standards.
• Understand Volatility: Slot players need to understand volatility. It plays an incredibly important role in how the game pays and will ensure you’re not caught off guard with unexpected dry rounds or low winnings.
• Use Bonuses to Your Advantage: Casino bonuses with fair terms and conditions can add a lot of value to your gambling experience. Don’t just claim bonuses blindly; compare and choose ones that add value.
• Bankroll Management: Setting a budget and making responsible gambling choices adds great value to your overall profit. Don’t let anything make you exceed your budget, no matter how tempting.
• Don’t Chase Losses: Chasing losses is one of the quickest ways to lose. It always seems like the next spin will trigger big wins, but keeping to your budget is far more important and likely to increase your profits.

How to Choose the Best Online Casinos for Real Money in America

Choosing the best online casino will require some evaluation to ensure the site offers the features you require. Each casino is different, and some would suit your gaming needs better than others.

We’ve ensured all the recommended online casinos on this page are licensed and secure, allowing you to compare the following points to choose the best match for your needs:

Compare Bonuses

From welcome bonuses to ongoing promotions, choosing the casino that matches your gaming needs will ensure you have loads of benefits to enjoy on your favorite games.

If you like playing a variety of games, look for bigger match bonuses, but if you’re a huge slots fan, consider an online casino that offers free spins; it’s a great way to discover new slots.

How to Compare Bonuses

Compare the bonus size, minimum deposit, and the wagering requirements. Also, ensure you can use the bonus on your favorite games if you’re hoping to play more than slots.

Can’t find the Bonus T&Cs?

The best online casinos are transparent with their bonus terms and conditions, clearly showing the wagering requirements and other conditions.

Visit the promotions page and choose the bonus you’d like to compare. There should be a link to the terms and conditions.

Compare Casino Games

The best online casinos offer a well-rounded selection of slots, table games, live dealer games, game shows, and more. However, finding the right site depends on what you want to play.

Some of our recommended casinos have over 10,000 casino games, but compare casinos to ensure there’s a great selection of the game category you’d actually use.

Are Online Casino Games Fair?

Online casinos operate under strict licenses that ensure fairness. Games also use RNG (Random Number Generator) software that makes results completely random.

An online casino cannot alter the fairness levels of games as these are set by the game provider. Third-party auditors test games at random to ensure fairness.

Best Game Providers

A top-rated online casino will offer games from multiple leading developers, including NetEnt, Pragmatic Play, Play’n Go, Microgaming, and more.

These game providers offer a wide range of slots, live games, crash games, and jackpot titles.

Compare Payment Methods

Understandably, you might want to use a payment method that you already have access to, such as a credit card. Top-rated casinos online accept just about all payment options.

If you’re looking for anonymous gambling or faster withdrawals, it might be worth considering crypto casinos. These are some of the best casino sites in the US.

Most Popular Casino Payment Methods

Top-rated American casinos accept credit cards, debit cards, e-wallets, vouchers, and crypto payment methods.

Some casinos will also allow you to purchase digital coins with your fiat payment methods.

While not all of the above-mentioned methods are supported for withdrawals, your safest bet is crypto or e-wallets.

Compare Withdrawal Times

In addition to fast payment methods, also check how long the casino takes to process payments. The best casinos online process withdrawals within hours, while others can take up to three days.

Cryptocurrencies are the fastest, as payments clear within minutes, while credit cards require 3 to 7 days to reach your account.

Compare the Interface

The user interface is very important as you’ll be using it constantly while looking for games, bonuses, and processing payments. Ensure it’s easy to use, fast, and provides the info you need.

Mobile casinos such as Telegram casinos are great if you’re planning to play more on mobile. These casino bots are very fast and easy to use directly in Telegram.

Should I Download A Casino App?

Interestingly, very few top-rated American online casinos for real money offer apps these days.

Mobile websites have become incredibly advanced, allowing you to easily and securely play your favorite casino games without having to download any software or additional apps.

Are Casino Games Limited on Mobile?

No, game providers and casinos strive for mobile-first, which means they develop every aspect of games and casino features for mobile.

Of course, you’ll still be able to access everything on your desktop as well, but your mobile device is just as capable.

Online Casinos vs. Land-based Casinos

It might seem unfair to compare the best online casinos in America to land-based casinos, but it really depends on your gambling needs and preferences. Let’s compare some of the main points to see what’s the right match for you:

Feature	Land-based Casinos	State-Licensed Casinos
Accessibility	Most are open 24/7, but you need to travel to play	Always available on your desktop or mobile device
Game Variety	Limited by space, and fewer game providers create land-based games	Thousands of games and new ones added almost weekly by over 100 game providers
Bonuses and Promotions	Offers comps to loyal players, including free drinks, food, and more	Rewards massive bonus cash bonuses from the first deposit. Also includes loyalty and VIP perks
Social Interaction	Strong social elements, including other players, dealers, and more	Some games, especially live dealer games, offer chat rooms, and you can participate in tournaments
Withdrawal Speeds	Can cash out at the cashier or check in the mail	The best online casinos complete withdrawals within minutes, but some can take a day or two.

Safety and Security of Online Casinos

Online casinos for real money in America are 100% safe and secure. These sites operate under strict gambling laws from international licenses, ensuring a fair and reliable gambling experience.

You can also use additional security measures with options such as Inclave casinos, offering better password protection and faster sign-ups.

Online Casino Real Money Myths Debunked

I’ve been in the gambling industry for more than 15 years. During this time, I’ve heard my fair share of tall tales and spurious claims, which is why I’m the best person to separate fact from fiction.

Naturally, I can’t cover every casino myth out there in the ether, but I can give you my expert take on the most egregious. So, without further ado, here are the biggest real-money casino myths and why they’re wrong:

Myth 1: Online Casinos Are Rigged

Fiction: Real-money online casino operators are out to scam players by offering rigged games that you can never beat.

🔎 Fact: Licensed online casinos for real money aren’t rigged. In fact, it’s the total opposite. Licensed casinos are highly regulated, which means they have to comply with strict rules regarding safety, integrity, and transparency.

In line with this, all casino games are certified as fair by independent testing organizations. While casino games do have a house edge, licensed operators are committed to providing a fair and enjoyable experience. 

Myth 2: You Can Always Beat the House with a System

Fiction: There are betting systems and strategies that guarantee you’ll make a profit each time you play.  

🔎 Fact: Gambling is an uncertain activity. It’s entertaining, and those in the know play for fun and see profit as a nice but not guaranteed bonus. That’s why the only betting strategy that works is bankroll management, like not wagering more than you can afford to lose.

Any betting system that claims to offer guaranteed profits is either based on fantasy or fatally flawed. A great example of this is the Martingale System. This betting system works in theory, but its fatal flaw is that it can’t be properly implemented due to casino table limits.

Myth 3: Big Wins Are Impossible

Fiction: Massive jackpots are only there to lure you in, and no one ever wins these prizes.

🔎 Fact: Saying that you can’t win massive jackpots playing real money online casino games is outright false. All games have a pre-programmed RTP (Return to Player) value.

This value determines how often, in theory, the game pays prizes. The complex calculations that go into shaping a game’s RTP value take into account jackpot payouts. Therefore, at some random point, online casino games are programmed to release their jackpots. Plus, many players claim progressive jackpots every month.

Myth 4: Casino Bonuses Are Always Good Deals

Fiction: Every single online casino bonus gives you an easy way to claim free money.  

🔎 Fact: Casino bonuses do allow you to get free cash and free spins, but some deals are better than others. I’ll take you back to my previous point about wagering requirements. The best online casino bonuses make it easy for you to claim big rewards.

A $3,000 deposit bonus might look good on the surface, but its value crumbles when you discover that the playthrough is 120x. The industry average is 40x, so this offer is three times worse than the top online casino bonuses. That’s why you should also check the wagering requirements before claiming real money casino bonuses.

Should You Play at the Best Online Casinos for Real Money – Our Verdict

The variety of the best online casinos for real money accommodate a wide range of players. We highly recommend that you compare casinos and choose the one that suits your gaming needs.

Both BetWhale Casino and Raging Bull are well-rounded online casinos that offer a generous variety of games, bonuses, and strive to deliver fast payments. We recommend starting there and see how they stack up to the gambling services you need.
