Online Casino Sites FAQ

Snippets of information regarding online casinos gambling in the US

Is online casino gambling legal in the US?

Online casino gambling is legal in three states: New Jersey, Delaware and Pennsylvania. Each have regulated industries with licensed online casino sites. You need to be located within the borders of one of these in order to gamble legally. Any player participating in online gambling outside of NJ, DE or PA through unlicensed sites is breaking US law.

Are online casinos sites in the US safe and secure?

Firstly, all casino sites listed on United Gamblers are fully regulated and compliant with state gambling law. Thanks to the emergence of sports betting industries across the states, online gambling has never been safer, meaning you need not sweat about online casinos that pay out, for instance. The more legitimate places to gamble safely online surface, the less need for players to seek out an illegal means of gambling. Going forwards, the industry will only become safer.

Which is the best US online casino for US players?

We all value different aspects of online casinos so it’s hard to give one answer among the wide selection that exist. Compared with your buddy, you may want to play a specific game at SugarHouse, while he/she may like the user interface of 888 Sport. We all have our different preferences. Your version of ‘best’ will more than likely differ to somebody else.

Which states have online casinos live currently?

As of now, it’s possible to legally wager at online casinos in Nevada, Delaware, New Jersey and Pennsylvania. Cross state wagering is not permitted thus only players within state borders can wager, eg. only players located in Pennsylvania can wager at casino sites in Pennsylvania. Geolocation technology will pinpoint your exact location prior to confirm your exact position.

What is a no deposit bonus?

A no deposit bonus is one of a number of incentives used by online casino sites and gambling sites in general to attract new players, or, reward existing customers. The offer requires no deposit to be made upon sign up, as the name implies meaning you have receive free money to play with. The standout no deposit bonus today is at DraftKings where you'll receive a free $35 for signing up.

How do I set up an online casino account?

Setting up an account is a straightforward process consisting of two main parts: 1) entering your personal details, 2) choosing a means of payment. You’ll also need to come up with a username and password to access your account but that takes care of itself. Providing your details are sufficient and you have money to play, the process shouldn’t total more than ten minutes.

How do I collect winnings from an online casino?

The process of withdrawing money from your account will vary from site-to-site and the payment method used. Payout speeds can range from 1-4 days, while there may be a minimum withdrawal amount set by the casino operator. Providing the same method to withdraw is the same as the one used to deposit, the process should always be a simple one to initiate by just clicking the ‘Withdraw’ button.

How do free spins work?

The use of free spins is another tool used by online casinos to encourage players to sign up. This type of promotion will permit a player a certain number of spins, without having to pay a dime. The value of each spin will vary according to the offer and casino so bear this in mind. But money can be made.

Do all online casinos offer the same games?

Generally speaking, yes. Most US casino sites cast the net wide to cater for everybody. Thus, you can expect an extensive offering of the most popular casino games. Less common games such as Craps and Baccarat may not be included at every online casino site. But with a collection of over 600 games in some cases, the probability of finding one for your taste is high.

Online Casino Sites in the US

Being able to gamble legally at an online casino is dependent on where you are located.

As it stands, only residents of New Jersey, Delaware and Pennsylvania can play online casino games legitimately

Delaware and New Jersey launched in 2013 with Pennsylvania the newest to launch as recently as July 2019. It's anticipated West Virginia will be next in 2020.

It's a common misconception for people to think Nevada has online casino sites too.

However, due to the potential harm an online launch would cause land based casino establishments, this remains off limits. At least for the time being. The popularity of gambling apps may see the tide eventually turn. So watch this space.

Here's how the US online casino industry shapes up today.

New Jersey

  • Online casino gambling: ✅
  • Launched: August 2013
  • Regulated by: New Jersey Division of Gaming Enforcement

The Garden State is the place to be for online gambling. Interest in NJ Casino gambling is expected to flourish through 2019 and beyond now it can be offered arm-in-arm with sports betting.

Offering close to 600 online games, few have performed better than Golden Nugget who remain a level above competitors 888 casino, Betfair, Caesars and SugarHouse.

The premier online gambling destination in the United States

With some of the leading sportsbooks looking to house sports betting and casino games within one app, as well as new faces trying to force their way in, the landscape of NJ online casino gambling will be one that continues to evolve.


    • Online casino gambling: ✅
    • Launched: July 2019
    • Regulated by: PA Gaming Control Board

    It may have taken some some time but online casino wagering is now a thing in PA. Gamblers have never had it better in the Keystone State with the launch of sports betting just a couple of months prior.

    Since online casino gambling in Pennsylvania launched in summer 2019, only a handful of online casinos including SugarHouse and Parx are live currently. Give it time though and that handful will only multiply.


    • Online casino gambling: ✅
    • Launched: November 2013
    • Regulated by: Delaware Lottery

    It almost defies logic that a state with a population of under one million patrons should be responsible for kicking things off in both industries.

    The first state to legalize online casino gambling

    The first to legalize online casino gambling back in 2012, DE has recently expanded its gambling industry to include sports betting. Residents of few states can claim to have the set of gambling options Delaware has available.

    Leading the way in terms of profits, they’re not though, unsurprisingly given the size of The Small Wonder.

    West Virginia

    • Online casino gambling: 🔜
    • Launch: Expected in 2020, latest 2021
    • Regulated by: WV Lottery Commission

    When legislation eventually come to pass in WV, we will be looking at a serious player in the online gambling industry.

    Only two states boast both sports betting and online casino gambling

    The Mountain State aren’t too far away from dining at the very top table of US gambling alongside NJ and PA. A case of 'watch this space'.

    How to Choose the Best Online Casino

    "LUCKY 7" Key Factors when choosing a casino site
    1. Only use regulated sites
    2. Does the site feature your favorite game?
    3. Read ALL the terms and conditions
    4. Does the casino cater for mobile gaming?
    5. The more payment methods the better
    6. Are the customer support options sufficient?
    7. Know your types of casino bonus

    Whether you reside in one of the aforementioned states, or, happen to be waiting eagerly for online casino gambling to arrive on your turf, it’s always wise to be aware of what to look for when choosing the best online casino site.

    Below are the key factors for you to consider:

    • Only use regulated sites

    We take it you’ll want your monies transferred upon winning, right? Well, this isn’t a guarantee of many offshore gambling sites who are known for not honoring wagers so steer clear of unregulated and illegal sites.

    To avoid being scammed, sidestep any gambling site that isn’t regulated within state jurisdiction. You can check out the safe and secure sites available in your state, here.

    • Does the site feature your favorite game?

    There really is no limit to the selection of games an online casino can house. State-of-the-art technology means your favorite game should be available for you to play - in theory.

    Make sure then to have a good nose around to see if the site meets all your needs - you don’t buy a house without having a look inside first, do you? (Yes, it is as important!)

    • Read ALL the terms and conditions

    It's no secret that casino sites are out for you not to win. The offer will always include a set of terms and conditions that must be followed if you are to stand a chance of making some cash.

    You're not alone in passing up the chance to read the t's & c's, we all do it. But before parting with your money, we recommend knowing the terms of the offer on the table. You may come unstuck otherwise.

    Betting bonus clued up us
    • Does the casino cater for mobile gaming?

      Chances are you’re going to want to play your favored game on your mobile phone. Fortunately, most online casinos have the graphics, payment facilities and gaming speed in built to make it possible for you to play whenever, wherever.

      Not making games accessible on mobile or even better on an app seems criminal thinking about it. This said, there may be casinos not yet up to speed so it’s important to investigate prior to committing.

      • The more payment methods the better

        We say this because, as a customer, you should be able to deposit and withdraw funds how you want.

        Not everybody is comfortable using their bank card online, while some may not know much about e-wallets or Bitcoin. Maybe you'd prefer to use a prepaid card to makes it easier to control your spending.

        When it comes to payment options, the more choice, the better

        An online casino with a wide range of different payment options online, offline, in-person or even over-the-phone is a minimum ask of any online casino offering.

        • What are the customer support options like?

        Whether the casino of your choosing lives up to its billing, there’s likely to come a point you need a query answering. And it’s important the online casino is able to see to your needs instantly, regardless of the time of day.

        A reliable Live Chat facility allows customer support 24 hours a day, 7 days a week and this is what you should be looking for. This way, no matter the time, day or night, instant assistance will be available.

        Live Chat provides customer support 24/7

        As with any online offering, casino sites are inclined to direct you the way of FAQ, Live Chat and e-mail before suggesting you call them. But don’t let this stop you picking up the phone if your issue is urgent and needs investigating without delay.

        • Know your types of casino bonus

        As a new player, you may be overwhelmed with the sheer number of online casino bonus offers you will come across. Amidst a crowded marketplace, sites will aim to attract new customers to sign up by offering an array of different welcome bonuses.

        But it's important to remember that it's you who holds the cards. You're under no obligation to sign up to a specific offer. Whoever you decide to sign up with is up to you.

        This said, before storming in, we do first recommend knowing the types of casino bonus on the market.

        Online Casino Bonus Types

        Casinos will entice new customers to sign up by offering a series of welcome bonuses. These exist in various forms, as you'll discover below.

        Before you go ahead and pick one though, it's important to know what the specific terms actually mean.

        Don't fall into the trap of not knowing exactly what it is you're getting, as many new players tend to do.

        Casino Bonus Offers: Key Terms
        • First deposit bonus - most common type awarded to new players upon first deposit being made
        • Deposit bonus - same as above but issued to existing customers as part of a promotion
        • No deposit casino bonus - the chance to earn free money without depositing a single dime!
        • Free spin bonus - spin the reels on a certain game for free and keep the winnings.
        • Reload bonus - a promotional cash offer for existing customers and to reward loyalty
        • Free play casino bonus - play for free and win real money up to a set amount or a period of time
        • Loyalty bonus - awarded to players signed up with an online casino for a long time
        • Referral bonus - refer a friend and receive a fixed bonus amount or a percentage of their deposit

        Online Casino Bonuses for New Players

        First deposit bonus

          The one bonus you’re likely to come across more than any other as a new player. First deposit casino bonuses offered 'up to' a certain amount, e.g. 100% deposit up to $100.

          Before becoming eligible new players must create a new account and make a first deposit. Using the example above, this would amount to anything between the industry minimum of $10 and a maximum of $100.

          The amount deposited will then be matched by the casino operator. In this case the offer is a 100% match. So, let's say you make a first deposit of $50. This will be matched with a bonus of $50 giving you a total of $100 to start gambling with.

          No deposit casino bonus

            Before risking your own money, you can play ‘on the house’. Such an offer, also known as a Free Money bonus, only comes into effect once you create a new account.

            No deposit bonus us

            The bonus requires no deposit to be made, hence the name. But bear in mind wagering requirements and withdrawal limits that come automatically with such an offer.

            Free spin bonus

              New players who enjoy slots should check out slots-only promotions, aimed with just slots players in mind.

              A free spin bonus offers the chance to play a certain game with nothing taken from your balance

              You'll be issued with a set number of spins which are credited to your account upon a deposit being made.

              As part of a welcome bonus, you may also be offered Free Spins No Deposit. Here, you can play and test the game without having to deposit.

              Can I win real money with free spins?

              Absolutely. Any winnings generated from playing your Free Spins will show up on your account balance. The offer may require wagering requirements to be met before you can withdraw as real cash however.

              Read on below for what is meant by a 'Wagering Requirement'.

              Online Casino Bonuses for Existing Players

              The offers aren’t just limited to new players though. Existing customers are also catered for.

              Reload bonus

              From time to time, a casino will reward committed players by adding to their deposit amount, albeit at a lower percentage than new players, so less than 100%.

              Usually, depending on the casino you can expect to see reload bonuses offered on a weekly basis or to coincide with a big event.

              Free play casino bonus

              Used by a casino to drive interest in a particular tournament. A free play bonus comes with a time frame in which it needs to be played.

              Or a playing limit carrying a maximum amount that can be wagered. If and when either expire, you will need to make another deposit.

              Loyalty bonus

              With the competition as intense as it is, online gambling sites have begin to realize the importance of retaining custom, alongside attracting new players.

              As such, casino companies are rewarding loyal customers who have been an active customer for a sustained period of time (between six months and a year) with a free spin bonus or a ‘monthly match’ bonus.

              Referral bonus

              Tell your buddy, a family member or somebody at work about how good your casino is and, providing they go on to create an account, you’ll be rewarded with a percentage of their first deposit.

              The refer-a-friend style of bonus is worth exploring but don’t be surprised to come across strict wagering requirements for you and your referred.

              What is a wagering requirement?

              A Wagering Requirement is the number of times you must wager your bonus before you can convert into real cash that can be withdrawn.

              Also referred to as a “play through requirement” or a “rollover”, this is how casino operators cover their backs to make sure promos do not prove super costly.

              Using an example, let's say you have 20 Free Spins and win $50 in total. If there is a X10 wagering requirement, you'll need to keep playing until you've spun through $500 ($50 x 10).

              Only once you've spun through $500 are you then able to withdraw whatever is left.

              Wagering Requirements vary from casino to casino and will range between 0 and 50.

              How to deposit money to your online casino account

              As mentioned, new customers only become eligible for most bonuses upon creating an account and making a deposit.

              In total, the process shouldn’t exceed 10-15 minutes. In fact, so long as you have all the necessary information to hand you should glide through the account set-up in half the time.

              To receive your bonus, follow the steps below, applicable across all US online casino sites.

              1, Enter personal details to create account

              Nothing out of the ordinary required. Just the standard information when setting up any online account, with the exception of your social security number perhaps.

              • Full name
              • Address (including state and zipcode)
              • Social security number
              • Date of birth
              • Mobile number
              • Email address
              Why do sites require my social security number?

              A common ask. Basically, casinos are viewed as financial institution by the US government and so need to abide by strict regulations which helping preventing money laundering. To see they do this the name, permanent address and social security number of a new player must be provided.

              2, Choose payment option and deposit

              The engine is running. You have an account. But now we need to add some fuel to fully ignite your online gambling career.

              How you fund your online casino account is a personal choice

              Being creatures of habit, we tend to opt for methods that have served us well in the past.

              Whichever way you prefer to move funds to your account, most online casinos offer a range of options to ensure everybody is catered for.

              Credit/Debit cards

                • VISA
                • Mastercard
                • American Express

                Hands down the most reliable and universally accepted payment option has to be VISA, with Mastercard not too far behind. Both are tried and tested and are renowned for offering maximum security.

                US Online casino payment methods

                How will you fund your account?


                • Paypal
                • Skrill
                • Neteller

                Despite added competition in the shape of Neteller and Skrill, PayPal remains the go-to e-wallet for many. Skrill is rated as one of the more convenient payment options, in part, due to its previous life as Moneybookers. Neteller, meanwhile, may not be as popular but still makes a strong case for a solid e-wallet option. You can't go wrong with either really.

                Bank Transfer/Offline

                • Western Union
                • Bank wire
                • E-check

                Prefer to send money offline? Bank wire allows for a transfer to be made from one company to another using your local ban. Western Union work in similar fashion where moving money via telephone and in-person is easily doable. E-checks, widespread across many online casinos, function the same way a paper one does, albeit, a little quicker!


                • Casino cashier
                • PayNearMe

                Pay-as-you-go by taking cash to the casino cage of the land-based establishment or to a 7-Eleven convenience store. In legalized states of course.

                Online Casino Games

                The variety of games on offer - all of which carry numerous online casino bonuses and promotions - goes way beyond what can be found at brick-and-mortar casinos.

                Despite the wide choice and well liked games such as Bingo, Baccarat, Keno and Caribbean Stud Poker, most of us are inclined to return to more traditional and long standing games.

                  Traditional online casino games are hard to beat
                  • Blackjack

                  A timeless classic and the most commonly played online game. One or more players compete against a dealer to try to get to the number 21 with the cards dealt, without going over. Various online versions can see some diversity in how the game is played but as a game with one of the smallest house edges among table games, its popularity stretches across the board.

                  • Roulette

                  The roulette wheel consists of red and black pockets numbered between 0 and 36. The goal is to call which pocket the ball - spun by the dealer - falls into. You can wager on red or black, odd or even or between 1-18 and 19-36. Or a specific number if you're feeling daring! These account for the most common and some of the easier wagers but a whole host of bets are available. The game is favored by new and experienced gamblers alike due to its simplicity.

                  • Slots

                  Played by the masses, slots are the backbone of any casino regardless of location. If you’re a newbie it’s probably best you stick with the 3-reel slots but that’s not to say you can’t enjoy your fair share of beginner’s luck. After all winning on the slots is purely luck based. In every online slot game, the destiny of your game will be decided by a Random Number Generator (RGN). The computer component used to provide a combination can be likened to the random element involved in rolling a dice.

                  • Craps

                  Talking of rolling a dice, that brings us nicely onto Craps. Which moves us on nicely to a game based solely on the roll of the dice. Players must wager on the outcome on each roll of a pair of dice and whether it can be matched. It’s a game that requires a fair degree of understanding and possibly a couple of sit throughs, before playing for real.

                  Land based casinos vs Online casinos

                  In the past, little came close to the bright lights and electricity of Vegas.

                  But is playing online now better than the real thing?

                  More of us are choosing to play online at our own leisure

                  Given how easy it is to access online casinos via mobile devices, more and more of us are swapping the suit for slippers and choosing to play online at our own leisure, rather than visit the bright lights of a physical casino.

                  What are the main differences then? Let’s take a look.

                  Land based casinos

                  There’s plenty to enjoy about a visit to a land-based casino.

                  The dressing up, the buzz, the socializing, the celebrations that come with beating the dealer - even the disappointment of a loss can be glossed over with a free glass of something.

                  The whole experience really is one to savour. Free accommodation. Free buffets to lure you back into the casino or indeed keep you playing. Such temptations can also be viewed as negatives however.

                  It’s easy to get carried away in the excitement of it all. Playing for longer than you’d planned and spending more than you set aside are just two potential issues.

                  There’s also the location of land-based casinos to consider. Some casinos aren’t too much of a hassle to get to. But many outside the city’s main border, or perhaps in another state entirely, can contribute toward unnecessary costs and wasted time spent travelling.

                  Las vegas casinos

                  There is certainly no shortage of iconic casinos along the Las Vegas Strip.

                  Online casinos

                  No such problem getting to an online casino in regulated states.

                  No need to dress up or make unnecessary small talk. In fact, you need not leave the comfort of your sofa. Required only is a mobile device/laptop and a fast and reliable internet connection.

                  You won’t be offered a trip to the local buffet as at a land-based casino but there's no shortage of promotional offers and perks to take advantage of.

                  Online casino bonuses can range from $10 to $500

                  It’s an offer that can be taken up at a time that suits you too so need to consult the diary.

                  Unlike the typical opening and closing times of a physical casino, no such restrictions come when gambling online; online casinos are open for business 365 days a year.

                  Be it 2.00 in the afternoon or 2.00 in the middle of the night, you can play around the clock.


                  How you gamble is entirely personal.

                  Clearly, the thrill of an ‘actual’ casino cannot be compared with. But it depends on circumstances and also your objectives for gambling. Are you out for a good night or are you out to try and make money?

                  There’s no saying which is better or worse but with online gambling in such easy reach - literally in our pockets - it appears more and more of us will be choosing to trade our suit and shoes for slippers and the sofa.

                  History of Online Casino Gambling

                  Overall, it’s fair to say, online casinos set the ball rolling in terms of online gambling in the US.

                  Who got the wheel spinning?

                  Microgaming and CryptoLogic are probably still arguing about who was first to market. But in truth, both of their respective products, The Gaming Club and InterCasino, played significant roles in developing the technology required to power the games and financial systems we play and use today.

                  Even now, Microgaming is one of the most trusted software providers and more than likely to be the operator behind your favourite online casino offering today. InterCasino, meanwhile, is a renowned name within the online casino world given its status as one of the longest-running online casinos in existence.

                  Neither would’ve been able to function had it not been for the Free Trade and Processing Act, however. The bill, passed in the Antigua and Bermuda, granted licenses to companies wishing to provide gambling services online and, in many ways, initiated matters to begin with.

                  Growing signs were alway there

                  The formation of the Kahnawake Gaming Commission in the late 90s paved the way for more and more companies to gain the gaming licenses needed to regulate online casinos.

                  This extended to other forms of gambling too and before the millennium arrived, the online gambling industry as a whole was hitting record levels - over 200 websites generating revenues of over $830 million.

                  But this was nothing compared with what was to come with the explosion of the internet and giant steps forward in technology.

                  The turn of the new century witnessed online casino numbers reach an estimated 8 million

                  With every year bringing more advancements in technology, smarter devices and the ability for more players to access their favourite games, the industry has continued to blossom.

                  Fierce competition

                  With more and more betting operators seizing the opportunity to get involved in a lucrative industry, the market increased further with many operators setting out to become the biggest and the best.

                  Not only did added competition this increase the options for customers, the overall standard of the industry evolved almost monthly with added features added time and again.

                  Progressive jackpots, slots based on tv shows and multiplayer games are just a few of the reasons why and how numbers have soared. And, crucially, continue to do so.

                  What of the future?

                  Graphics used for online casino games nowadays resemble those seen in digitally animated films, making the online casino experience as true-to-life possible.

                  The future for the casino industry is clearly online

                  Whether you’re a traditionalist or not, the future for the casino industry is clearly online.

                  It’s almost inevitable the $1 trillion mark will be passed going into the next decade, a landmark that will confirm the online gambling industry as the fastest growing market in the world.
