Other Online Casinos
The top 10 free online casinos we reviewed are some of the best offshore picks, and they’re available anywhere in the US regardless of whether online casino gaming is legal in your state. That said, in states where online real money casinos are legal, you can play legally with a US-based casino.
With the exception of Riversweeps, the following are some of the best online casinos for real money available for legal gaming in Michigan, New Jersey, West Virginia, and Pennsylvania:

You’ll find tons of variations on classic games like blackjack and roulette, plus a steady flow of new slot games to keep things interesting. Riversweeps also has a few jackpot slots, although we’ve found that the jackpots never tend to grow all that large.
Riversweeps doesn’t offer live dealer games at this time, but the casino appears to be moving in that direction. For now, you can still play virtual video poker and enjoy relatively high betting limits on most table games.
What we like:

Golden Nugget is one of the most legit online casinos, with roots in New Jersey’s Atlantic City casino district. This online casino specializes in slots and has over 800 slot games available.
What’s especially neat is that you can filter games by slot style, game developer, software provider, and more. So, you can easily find the best slot games for whatever mood you’re in. Of course, navigating through 800 games can still be tricky, so plan to spend some time familiarizing yourself with the casino lobby when you’re just starting out.
Golden Nugget also has more than 45 table games and 15 virtual video poker machines. Plus, you can play blackjack, roulette, and baccarat at any of 16 live dealer tables. Not all of these tables are open 24/7, but several are so there are always dealers available.

However, it’s growing rapidly, with tons of new slots slated to come online in the months ahead.
One thing that makes Turning Stone interesting is that it offers leaderboards for top games, so you can compare your luck and skill against that of other players. Top players can earn prizes up to $800,000, so it pays even more to win at Turning Stone.
Turning Stone also offers a massive 500% welcome bonus for new players. It comes with a 45X wagering requirement. There’s no promo code required to claim the bonus – all you have to do is sign up.

How to Select the Best Online Casinos for Real Money
Wondering how to pick the best online casino for real money? We’ll explain some of the key factors we consider when evaluating the best online casinos that pay out in the USA.
Range of Games
The first thing to look at when searching for a online casino USA for real money is the range of games it offers. Ideally, an online casino will offer hundreds of slots plus classic table games like blackjack, roulette, and baccarat. Many casino online gambling sites, including our top pick, Bovada, also offer live dealer games.

Behind every great online casino is a great software provider. Top software providers include Evolution Gaming, Real Time Gaming, Visionary iGaming, NetEnt, and Betsoft. These software providers are leaders in the industry and are widely considered to be trustworthy.

Betting Limits
Most online casinos put limits on the minimum and maximum you can bet on specific games. At Ignition, for example, the blackjack limit is $2,500 per hand. If you want to bet more, look for VIP or high roller tables that offer raised limits for loyal players.
Live Gaming
Live dealer tables are now a common feature at the best real money online casinos. These allow you to play blackjack, roulette, baccarat, and other popular casino games with a real dealer. Make sure that live tables are available 24/7, like they are at Bovada and Wild Casino.
Payments
Depositing money to your casino account and withdrawing your winnings should be as easy as possible. All of the best online casinos in the USA accept debit cards and credit cards, as well as cryptocurrencies like Bitcoin. The table below shows payment methods and payout times for the top online casinos:
| Payment Methods | Minimum Deposit | Payout Time | |
| Bovada | Credit card, debit card, MatchPay, Zelle, Bitcoin, Bitcoin Cash, Litecoin | $20 | 1-2 days |

At Bovada and MyBookie, you’ll also find mobile-friendly websites that you can access right from your smartphone’s web browser. Be sure to try out the mobile site or app to make sure it’s easy to bet with and easy to navigate.
Security
All of the top USA casinos online take security extremely seriously. They are licensed to operate in their home countries and use encryption to keep your account secure.
Are Online Casinos Legal in the US?
Online casinos are legal in New Jersey, Pennsylvania, West Virginia, and Michigan. Delaware has also legalized online gambling, but only through the state lottery. In Nevada, online poker is allowed, but not online slots or other casino games. In most states, online real money casinos aren’t legal at all.
Offshore Casinos
The fact that online casinos are only allowed in 4 US states means that most Americans can’t legally play online casino games. However, offshore casinos are available throughout the US.
Offshore casinos are based outside the US, typically in Europe or the Caribbean, and aren’t bound by US gambling laws. These casinos are available in every US state, regardless of whether gambling is legal or not. Many have been around for decades and are regulated just like US casinos, but in their home countries.
While gambling with offshore casinos is illegal - even in states that offer legal online casino gambling - enforcement has historically been lax. In fact, offshore casinos remain one of the most popular ways for people to gamble online even in states that have legal US-based online casinos.
What Games Can You Play at Online Casinos?
Real money online casinos offer tons of different games, including classics like blackjack, roulette, poker, baccarat, keno, and craps. Some casinos even offer game show games like Monopoly or Wheel of Fortune.
Poker, too, is extremely popular at online casinos. Bovada, BetOnline, and Ignition all offer poker tournaments with cash prizes, and most of the US casinos we reviewed offer virtual poker games.
Live Dealer Games
Many casinos now offer live dealer tables where you can play blackjack, roulette, baccarat, Super 6, and even Hold’em. These casinos connect you with a real dealer by video chat, so the experience is as close as you can get to actually being on the casino floor.
At casinos like Wild Casino and Bovada, live dealer tables are available 24/7. In addition, Ignition also lets you choose your dealer and betting limits when playing live dealer games.
Bonuses at Online Casinos
All of the best online casinos for real money offer welcome bonuses to attract new players and set you up for success in your gaming. These bonus offers can add up to a lot of money, so it’s important to understand the different types of bonuses and how they work.
Deposit Match Bonuses
Deposit match bonuses are the most common type of bonus offer at online casinos in the US. The size of your bonus is directly linked to the size of your first deposit. For example, at Bovada, you’ll receive a 125% match up to $1,250 - so if you deposit $1,000, the casino will give you $1,250.
Free Spins
Some casinos, like MYB Casino, offer free spins on hot slot games. With free spins, you can bet on slots without putting any money down. Most free spins let you wager on all the possible slot lines.
No Deposit Bonuses
Online casinos with real money no deposit bonuses are rare, but they’re worth keeping an eye out for. That’s because an online casino no deposit bonus gives you money simply for signing up for a new account.
You can start playing immediately without ever putting your own money at risk. If you play through your whole bonus and want to walk away without ever making a deposit, you’re free to do so at a real money online casino with no deposit bonus.
Bonus Terms and Conditions
Most welcome bonus offers come with a few terms and conditions. Here are the most important to know about:
- Wagering Requirement - The wagering requirement is the amount you need to bet, relative to the bonus amount, before you can withdraw the bonus funds or your initial deposit.
- Time Limit - Some casinos, like BetOnline and Wild Casino, put a time limit for how long you have to meet the wagering requirement. If you miss this limit, your bonus funds will disappear.
Online Casinos Deposits & Withdrawal Methods
Online casinos offer a variety of different ways to fund your account. All of the top casinos we reviewed accept debit cards and credit cards as well as Bitcoin. Most also accept other popular cryptocurrencies - for example, at Wild Casino, you can fund your account with Bitcoin Cash, Litecoin, Ethereum, Ripple, USD Coin, or Stellar.
When it comes time to make a withdrawal, you should have many or all of the same payment options. Most casinos can process payouts in 24-48 hours, although some like Planet 7 may take up to several days to get your money to you.
