US Online Casinos

Gambling in casinos is a pastime that goes back centuries, and while Las Vegas and Atlantic City are still the ultimate casino destinations in the US, the rise of online gambling has led to a big shift in how and when people are able to play their favorite games.

Casino gaming is only available in certain states. Gambling laws are constantly changing in the US, and mostly in the right direction for those hoping to register and play throughout the country. On this page, you'll find out everything you need to know about US online casinos.

Frequently asked questions about online casinos

On this page, you will learn all about the best online casinos and the different options available to you. But for a quick overview, just read these FAQs.

What is an online casino?

An online casino takes all of the games that you'd see in a brick and mortar casino in Las Vegas, Atlantic City, or wherever else you get your fix, and allows you to play them on your computer or mobile.

You can play on your own with one of the games developed by casino game providers, or you may have the option to play with live dealers for a more interactive and familiar experience.

Which US online casinos are the best?

The below casinos are all excellent options for gamblers in the US:

In which states is online casino gaming legal?
  • Delaware
  • Michigan
  • New Jersey
  • Pennsylvania
  • West Virginia
Can I claim casino bonuses as a new customer?

Absolutely! On the bonus list at the top of this page, there are plenty of casino bonuses to choose from. After claiming one, you may be able to claim existing customer bonuses from the same casino site. Check their 'Promotions' section to see if this is the case.

Are all online casinos for real money?

All of the online casinos listed on Bookies Bonuses allow real money wagering, but there are state restrictions. Only five states have legal online casino gaming at the moment, and each online casino may not be legal in all of those states.

If you want to try out the games for free, some of the casinos may have this option as well.

How do I know if online casinos are legit?

We only list fully legalized, safe and secure online casinos on the Bookies Bonuses site.

Displayed at the bottom of their casino pages should be their license information and other relevant details.

Which casino games are the best for winning money?

Casino games are chance-based rather than skill-based, but some have a higher probability of winning whereas others give you an opportunity to win more money.

Blackjack, craps, baccarat, and three-card poker tend to have the smallest house edge, whereas slot games give a bigger edge to the house but in some cases allow you to win huge jackpots.

Can I use PayPal to play at a real money online casino?

Yes. A range of online casinos, including the below, accept PayPal as a payment method:

  • Bet365 Casino
  • Unibet Casino
  • 888casino
  • FanDuel Casino
  • BetMGM Casino
  • Caesars Casino
  • Barstool Casino
  • BetRivers Casino

Best Online Casinos

Nowadays, most if not all online sportsbooks have a casino offering so that they can provide a one-stop-shop for gamblers who like a variety of different options.

There are also some brands that focus solely on casino gaming. These are not necessarily better than the casinos you find on sportsbook-first websites. 

In fact, the likes of Unibet Casino has such great variety that the brand would probably still be hugely successful even if they did not have online sportsbooks too.

To be considered one of the best real money online casinos, you need to have a large selection of games across the various different categories - slots, table games, jackpots, and preferably live dealer options.

A range of payment methods and fast payouts are also important to players, while a lucrative welcome bonus and a range of existing customer promotions make a big difference as well.

Mobile gaming capability is also key, and that is where Bet365 excels.

    Online Casino Games

    There are countless different types of casino games played all over the world, and everybody has their own favorites.

    Not only are there tons of casino games, but there are multiple variations of some of the games with unique rules and stipulations.

    While there are too many game types to list, below are the core games that you will see on every online casino site in the US.

    Online Blackjack

    One of the most simple and popular casino games around, blackjack is a staple of all online casinos.

    You are dealt cards until you choose to stick, and the aim is to get as close to 21 as possible without going over it.

    The dealer has the same objective, and you are essentially in a one-on-one battle with them.

    Each hand only takes a few moments, so when you log in to an online casino, you can have an ultra-quick blackjack session or sit there for hours enjoying the game.

    Some online casino sites may have blackjack games with live, real-life dealers, or you can choose one of the many different types of virtual blackjack.

    Blackjack house edge

    Ben Smith
    Ben Smith

    Blackjack is one of the only casino games in which your skill level does actually matter, even though it is still massively luck-dependent.

    If you use basic blackjack strategy, the house edge can be around 0.5%. That means that the house has a 50.25% chance of winning each hand, compared with your 49.75%.

    But if you make bad decisions, such as choosing to hit, stand, split, or double down in the wrong situations, then that house edge can increase.

    But at 0.5%, blackjack (if played properly using basic strategy) has one of the lower house edges in casino gaming.

    Online Roulette

    Roulette is one of the oldest casino games and one of the easiest to understand and play.

    There is a wheel with pockets numbered from 0 to 36, and the player simply bets on what number they think the ball will land on when it is spun by the croupier.

    You can pick as many numbers as you like, or you can choose red or black, odd or even, or certain sections such as numbers 1-12.

    With online roulette, you can play the classic version, or jacked up versions with certain bonuses. One of the best live roulette games is lightning roulette, where for each spin, a handful of numbers have multipliers applied to them which increases the potential winnings massively.

    Bet MGM Casino Games Roulette

    Online Casino sites have plenty of options for roulette and other games.

    Online Poker

    Traditional online poker games in which you play against other users belong in a different category altogether and won't be found on an online casino site, but there are many different types of poker that you can play with online casinos either on your own or with live dealers.

    Video poker is similar to slot machines. You are drawn a random sequence of cards and you can then discard some before a second draw from which you must create a winning hand. Depending on the variation of the game you are playing - for example, Jacks or Better, Deuces Wild, or Joker's Wild - the payouts and rules vary.

    You can also play Three Card Poker on some online casino sites. With this game, you get three cards and try to beat what the dealer has by having a better hand.

    Online Slots

    Slot machines are the bread and butter of any real money online casino site. There is by far the widest variety in this area, with 888casino alone having more than 1,000 online slot games.

    There simply could not be more to choose from. Most games have a similar premise - you simply go for a spin and hope the reels match up in order for you to win big.

    Games are themed, so you can find something that suits your taste to make the experience even better. You can sort by themes like Ancient Egypt, Movies, Sport, The Wild West, and more.

    Lots of the games are provided by developers like NetEnt, Microgaming, and IGT, and you can find their titles across multiple online casino sites in the US.

    Other Casino Games
    • Craps
    • Keno
    • Sic Bo
    • Baccarat
    • Pai Gow
    • Bingo

    Recommended Online Casino

    FanDuel Casino

    Bet $5, Win $300 in Bonus Bets + 3 Months of NBA League Pass

    For a wide variety of games, FanDuel is an outstanding option for gamblers. With upwards of 1,000 online slots on offer plus an impressive selection of table games, the site truly leaves no stone unturned. There are multiple variations of blackjack, roulette, video poker, and other popular games.

    Online Casino Payments

    Deposit and withdrawal options are very important within online gambling, as users need to trust the operators to facilitate safe, secure transactions with reliable and familiar payment methods.

    Fortunately, real money online casino sites generally do a great job of this, and Americans can use some of the below payment options.

    Online Casino Deposits

    • Visa
    • MasterCard
    • PayNearMe
    • Vanilla
    • PayPal
    • Skrill
    • ACH/eCheck
    • Online Banking
    • Wire Transfer
    • Cash In-Person
    • Play+ Card
    • Venmo

    Online Casino Withdrawals

    • PayPal
    • Skrill
    • ACH/eCheck
    • Online Banking
    • Wire Transfer
    • Cash In-Person
    • Play+ Card
    • Venmo
    • Check

    Of course, not every online casino will have all of the above payment methods available, but all of the operators listed on Bookies Bonuses at least have a solid selection.

    PayPal is the most popular payment method because of its fast and secure transactions that take place without the user needing to share full bank details with the casino.

    It also helps that PayPal has established itself as a prominent payment service in the US and worldwide.

    Casino Bonuses

    Casino bonuses are offered as a welcome package by all online casinos, and they can be given out in various ways.

    If you are joining a betting site that has a sportsbook and a casino, you will need to choose between the two welcome offers when registering with that operator.

    Similar to sportsbook offers, refunded wagers and deposit bonuses are among the types of online casino bonuses you can claim in the US.

    Types of Online Casino Bonuses

    • Deposit Bonus - The online casino site gives you a bonus when you make your deposit
    • No Deposit Bonus - You receive a bonus without even having to make a deposit
    • Bonus Spins - Spin the reels on an online slots game without having to pay
    • Second Chance Wagering - Have any losses refunded to you up to a specified amount
    • Freeplay - Play for some free fun and enjoyment

    There are also various casino bonuses that are usually for existing customers. These promotions are provided as a way to keep existing users engaged and reward them for using the online casino.

    Existing Customer Online Casino Bonuses

    • Reload Bonus - Get rewarded for adding money to your account on certain days
    • Loyalty Bonus - Given out as a thank you for being a loyal customer
    • Referral Bonus - Have a friend register using your link or code, and receive a casino bonus

    Best Casino Bonuses

    Bet365 Casino

    Bet $5, Get $200 or $1,000 First Bet Safety Net

    When you register with Bet365 Casino, you can claim the 100% Casino New Player Bonus of up to $1000. Wagering requirements for this bonus are 20x, and you must complete these requirements within 60 days.


    Unibet Casino

    $500 Second Chance Bet

    The Unibet Casino New Player Offer lets players effectively choose how much of a bonus they way, since 50% of their deposit will be matches up to $1k. There is a 10x turnover, but this is still on the lower end of other casinos.

    Online Casino Apps

    Mobile betting and gaming make a huge part of the online gambling ecosystem in the US, so it is no surprise that most operators put lots of attention on their apps.

    What makes life even easier is the fact that many gambling companies have an app that features both their sportsbook and casino offering.

    You can place your sport wagers and play casino games all in one app, whether you are at home or on the move.

    There may be exceptions to this as some firms may prefer to have separate apps for their sportsbook and casino. BetMGM actually has a sportsbook app on which you can play casino games, plus a standalone online casino app.

    Online casino apps - What to look for

    Ben Smith
    Ben Smith
    • Mobile selection - Are the same games on offer via the app vs the desktop site?
    • Functionality - How easy is it to download, install, and use?
    • Languages - Are multiple languages supported?
    • Promotions - What online casino promotions are available through the app?
    • Payments - Are you able to deposit and withdraw easily on the app?

    Online Casinos by State

    Real money online casino sites and apps are available in the following states:

    Different operators are available in each of those states, and with online casino sites opening up in new territories all of the time, the landscape is constantly changing.

    Online Casinos DE

    The State of Delaware legalized online casinos and poker in 2012.

    Sports betting is also legal in the state but there is currently no online sportsbooks there because the Delaware Lottery is yet to issue regulations.

    Gamblers in Delaware can head to a land-based casino if they wish to place sports bets, and then can also play casino games there - but that option is also available to them online through casino-only platforms.

    Online Casinos MI

    Online casinos are legal in Michigan and have been since December 2019.

    Gaming in the state is regulated by the Michigan Gaming Control Board, and you can see its logo on each of the legal online casinos in the state.

    A wide range of online casino sites are available in Michigan, and some excellent casino bonuses are offered by a number of them.

    Online Casinos NJ

    In-state online gambling has been allowed in New Jersey since 2013. This state is among those that have been at the forefront of legal wagering in the United States.

    The Garden State has been associated with gambling for decades, so it is no surprise that its significance within the industry has continued through the transition towards online casino gaming.

    Online Casinos PA

    On October 30, 2017, a bill that legalized online gambling in Pennsylvania was signed into law and that paved the way for online casino sites to launch in the state.

    Casino gaming is now a big part of the economy in PA, with only Nevada generating greater commercial revenues within the industry.

    Various sportsbook sites have launched in the state in recent years, with some of them also having a casino section that people in Pennsylvania can use.

    Online Casinos WV

    March 2019 saw West Virginia join New Jersey, Pennsylvania, and Delaware by becoming the fourth state to legalize online casino gaming.

    Legal online casino and poker options were introduced to the state through local casinos, and now a wide range of brands have opened their doors to people in the state.

    With online sportsbooks also being active in West Virginia, there are plenty of options for gamblers.
