Casino Sites USA | Best US Legal Online Gambling Sites [September 2020]

At OLBG we strongly recommend that you only wager with legal online casino sites in the USA. We have all the information available to you so that you can understand which sites you can bet with legally in whichever state you are located in or planning to visit. With more than 20 legal casinos live in NJ we have a whole section dedicated to online casino sites in New Jersey and another to PA Casino Sites 

Legal Online Casino Sites By State  

Which States Sites Live What’s Next Total Sites Tell Me More 
New Jersey 23 More Coming Soon Unlimited See List of Sites
Pennsylvania  10 More Coming Soon 12 See List of Sites
Delaware 3 That’s It 3 See List of Sites
West Virginia  1 More Coming Soon  15 Tell Me More
Michigan  0 Coming Soon 15

As you can see, New Jersey is streets ahead when it comes to legal gambling sites in operation. 

Pennsylvania went live with online legal casino sites in July 2019 and has grown to a good number already. The only other states where legal online casino gambling is permitted currently are Delaware and West Virginia. There are three brands live online in DE but all are overseen by the state lottery with the same software providers so are essentially the same experience. West Virginia is live with DraftKings casino and more will follow soon.

Michigan approved online casino sites at the end of 2019 in law which will allow up to 15 online casinos in the state. We expect these to start going online later this year.   

Whilst legal land based casinos are available in many states, it will be some time before online casinos catch up. The growth of legal sports betting online is likely to spread much more quickly but we expect online casino gambling to gradually become more widespread in time. 

Remember though, you do not have to live permanently in NJ, PA, DE or WV to be able to gamble there legally online, you just need to be physically present within state boundaries at the time of making your transactions and playing the casino games of your choice. Many people in bordering states will visit one of these states to open their casino accounts online and to play the games of their choice. With the number of generous sign up offers available including some very attractive no deposit offers then it is easy to see why people think the journey is well worth it.

  • Legal Online Casino Sites Delaware

    There are three legal online casino sites in Delaware

    • Casino Delaware Park
    • Dover Downs 
    • Harrington Gaming Online 

    Delaware has offered legal online gambling since 2012. All three of the states brick and mortar casinos have a live online site or mobile app. 

    However legal gambling in Delaware is run by the state lottery so these sites are very similar in all but brand name. They are each powered in a partnership with 888 and Scientific Games. There is a possibility that Delaware may expand the number of online casinos in the future. 

  • Legal Online Casino Sites West Virginia

    Gambling online in West Virginia is legal. Each of the four racetracks in the state and the one land based brick and mortar casino may run an online casino or mobile app. 

    We expect the West Virginia online casino sites to go live during 2020 when they will include 

    • The Greenbrier Casino
    • Mardi Gras Casino
    • Mountaineer Casino
    • Hollywood Casino
    • Wheeling Island Online Casino 

    Mountaineer and Hollywood are partnered with William Hill whilst Mardi Gras and Wheeling Island have a partnership with Miomni. Fanduel Sportsbook are partners with Greenbrier so expect to see Betfair Casino providing the gambling arm here. 

  • Growth of Legal Online Casino Sites Through the States

    This is the number of legal casino sites live now. But how will this change?

    • New Jersey (23)
    • Pennsylvania (9)
    • Delaware (3)

    New Jersey is clearly leading the way with 23 online casinos operating already. Unlike with NJ Sportsbooks, where skins are restricted to three per land based operator, New Jersey licence holders can run unlimited numbers of casino skins. So this number is expected to keep growing until either some control is placed on it or it becomes too competitive for all of them to operate. This should be good for the consumer as the competitive nature of the industry should lead to great welcome offers, products and retention programs. 

    Pennsylvania currently allows for just one skin per licensed operator going online. Also in PA, each license needs to be applied for separately, with slots games, table games and poker being different licenses. At a cost of $4m per license this is also limiting the number of operators.

    Delaware is towards the other end of the extreme compared to NJ. Whilst there are three different casino brands they are all in effect the same as they are all run by the state lottery. 

  • What to Look for When Choosing a New Online Casino

    Don’t choose your casino on the welcome offer alone. 

    Welcome offers and promotions last for just a few days whereas I expect you are looking for a casino you can play regularly for months and even years into the future.

    Don’t get drawn into a bad casino just because the bonus looks great.

    Read our expert reviews of each casino and select the one that looks like it is what you want for a long term online casino experience.

  • Choose the right Online Casino Welcome Offer

    Often new players are attracted by the bigger bonuses.

    Deposit match bonuses that they can not actually afford. Often players will choose the offer that says it will match up to $1000 on the first deposit, but then only deposit an affordable $100.

    The bigger the bonus, usually the bigger the rollover requirements, and you could have deposited $100 elsewhere and had to turn it over fewer times.

    Also consider signing up using a sportsbook bonus or free bet as if you like to wager on sports, sometimes these offers can be more generous or suitable than the casino offers. We are seeing some particularly good New Jersey sportsbook deposit bonus offers.

  • Understand the Casino Welcome Offer

    Take a look at the range of welcome offers, and understand how each works before diving in. Our reviews are updated daily to show the current welcome offers available. 

    By clicking a link to an offer on OLBG you will get no nasty surprises or an offer that is different from the one you are expecting. At the same time, it is important to read and fully understand the full terms and conditions of every offer advertised so you know what to expect from your new welcome offer and New jersey online casino experience.

    There are many types of offers, from straight-up free credits to bet with just for registering as a player, to a bonus that will be the same as your first deposit value.

    Many offer both of the above!

    The most important thing to consider and understand is what you have to do to turn your bonus money into real money you can withdraw. I’ll make no secret that it is very difficult to do, but some are easier than others.

    Look for the lower bonuses and lower rollover requirements for a start.
