The Growth of Legal Gambling Sites USA 

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 Michigan, 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 allows up to 15 online casinos in the state. 

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 sites 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,MI, 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.

    In addition to the casino sites above there are three legal online casinos 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.


  • How to Choose The Best Online Casino for You

    There are a number of things to consider before registering with a new online casino app. You'll want to ensure that if you are going to install an app on your mobile, it will be the one that is right for you to prevent you from having to chop, change and keep switching apps.

    So here we have a few steps you can take, quite quickly to discover the right online casino app for you

    1. Use Legally Licensed US Online Casinos
    2. Read Online Casino Reviews
    3. Welcome Bonus Offers
    4. Slots Selection
    5. Games Available
    6. Live Dealer Options
    7. Banking Options & Withdrawal Times
    8. Mobile Performance 


    Use Legally Licensed US Online Casinos

    The first step to consider is whether you want to use a legally licensed casino or take a chance with an unregulated offshore company. The main difference between the two is the security, backup and protection you have should a dispute occur.

    Type Protected? Safe?
    US State Licensed
    Offshore unlicensed

    Offshore casino sites have long been in use and there are grey areas in regards to the legality of use and whether these companies should accept players and deposits from us residents. There have also been horror stories of companies disappearing overnight and disputes over big wins, generally with the players paying the price.

    You have a safer option of registering and using a state-licensed online casino in the US

    OLBG will never list any unlicensed casinos on our pages, and all reviews are undertaken in the knowledge that they are operating 100% legally with gaming board licenses.

    Read Online Casino Reviews

    If you are considering using an online casino for the first time, you'll find they are plainly very different from land based operations. It is no surprise outside of game availability you may not know what to expect.

    Don't worry there are no nasty surprises, however, we have a team of extensively experienced online casino players who have years of experience both here in the US and in Europe of what makes an online casino a good option for players new and old.

    We recommend reading all casino reviews available for your state so you can find out what to expect inside and the range of wagering options and rewards programs they have in place, as well as any welcome-bonus offers you could take advantage of when you sign up.

    Welcome Bonus Offers

    Welcome bonus offers for online casinos are a nice way to try them out. Give them a test drive if you will.

    However, too much focus is often put on the welcome offers available and not the actual product behind the bonus. 

    Remember, you are choosing an online casino to use recreationally for far longer than any welcome bonus will last, and for that reason, it should be the last consideration when choosing which online casino to join. 

    Bonus offers almost always have a wagering requirement attached to them, and the rule of thumb is that the bigger the offer, the bigger the wagering requirement will be before those bonus funds can be turned into real and withdrawable cash. for more information take a look at our casino bonus rollover article which explains in more depth how to choose a bonus.

    Slots Selection

    The main reason people choose to play casinos online is the ease of which you can play online slots, with no inconvenient hand-pay procedure for semi-good wins. Land a huge bonus round win, and you'll not be waiting for someone to come check your machine and give you a ticket. The win goes immediately into your balance.

    So, how do you know which online casino has the best slot game selection? Well, the first thing to consider is that bigger is not always better. There are some casinos with thousands of slot games available to play, they will include the top slot providers and many games, but it may be a bit of a task trawling through to find the game you want to play.

    Consider an online casino slot selection that still uses the top providers but lists maybe 200-300 slots at most. This is till a huge variety and you'll be sure to find the most popular and newest slot games online

    Games Available

    Outside of slots, there are few thrills than playing the tables, be it, Roulette, Blackjack or craps. versions will be available at all online casinos, so there is little differentiation between each. Where things can become interesting is when using live dealers for online casinos.

    Live Dealer Options

    Live dealers for online casinos has been a huge growth area as they have been introduced to online casino gaming in states like New Jersey and Pennsylvania. Evolution are the biggest provider of this type of online casino gaming to online casino operator and have recently acquired their biggest competitor Ezugi. This has provided them with a near-monopoly of supply and with good reason, it is the highest growth area of online casino gaming by far.

    Evolution have also gone as far as to release the worlds first live online craps game which promises to be yet another game-changer in the US online casino market.

    Banking Options & Withdrawal Times

    A flexible arrangement for banking options to fund an account and to make withdrawals is always a plus when choosing which online casino to select. 

    Banking options tend to be slow for withdrawals so the growth of online eWallet solutions being available is to the customers benefit, as is the withdrawal of sometimes having to go to a land-based casino to fund and withdraw from an account. Our online casino reviews contain the latest banking option info so you can make an inform choice on which casino would best suit the way you would like to manage your account.

    Mobile Performance

    And of course, the very nature of online availability of casino play will utilize the ability to play online whenever and wherever you choose from your mobile device. Modern online casinos are all optimized for mobile play, understand the demand from players.

    With legally licensed casino operators, you will have to be within the state boundaries of the online casino you are playing, and geo location from your mobile will need to be applied to verify your location to access these sites
