DraftKings Sportsbook

If we’re talking about the number of operative states (eleven), then there’s no company that can compete with DraftKings. But what about the betting site - is it actually any good?

Well, in a word, yes. No matter the extent of your betting experience, DraftKings will take care of your wagering needs and guarantee you an excellent online betting experience time and again.

Perhaps, the company’s biggest weapon is the fact it’s powered by leading sportsbook provider, Kambi, who have a proven track record of delivering premium sportsbooks for many global sports betting brands.

And while there are unquestionably other companies that do certain things better - for instance, FanDuel looks more attractive, Bet365 offers an incredible number of markets - DraftKings is the most complete sportsbook for the American bettor.

  • Available in eleven states (most in US)
  • Ideal for bettors of every level
  • Powered by global sports betting provider, Kambi

FanDuel Sportsbook

Like all great rivals, wherever DraftKings is mentioned, FanDuel is never far away! FanDuel’s superb online sportsbook and app have been a roaring success in every legal sports betting state it has entered so far.

Maybe this is no surprise given the company’s roots as a provider of Daily Fantasy Sports before stepping into the sports betting ring in 2018 - the opportunity to tap into an existing US audience has certainly helped FanDuel in that respect.

But that’s not taking anything away from the product itself, which, to date, is live in ten states. The FanDuel sportsbook offers a superb user experience on the mobile app and the developers haven’t forgotten about the bettors who still prefer to use the web-based platform - this is nicely done too!

Aesthetically, the product is clean and a well-considered layout makes the site and app thoroughly enjoyable to use.

PointsBet Sportsbook

Go back to January 2019 and very little was known about the Australian online bookmaker, PointsBet. Today, it’s almost impossible not to know about one of the fastest-growing sportsbooks in the country.

A key reason behind PointsBet’s popularity thus far is the speed at which the company has expanded its US footprint. New Jersey, Indiana, Illinois, Iowa, Colorado, and Michigan all have PointsBet available, with access to further states in the pipeline.

However, the company’s innovative type of sports wagering, PointsBetting where winnings (and losses) are determined on the accuracy of a bet and not the final outcome, has proved a massive hit with bettors seeking an alternative to traditional fixed odds wagering.

As the only US sportsbook that can offer this, in addition to the partnership with NBCUniversal, PoinstBet has quickly developed into an established brand and a standout option for bettors amid strong competition.

Why PointsBet is so popular

  • Available in six states

  • Exclusive sportsbook partner of NBC Sports

Golden Nugget Casino

Golden Nugget has a library of over 600 casino games which eclipses that of any other online casino. In addition to a high-quality mobile app, great banking options, a good level of customer support and reliable software, you can see why this the go-to online casino in New Jersey.

As complete as it gets for an online casino in 2021

When you consider Golden Nugget’s strong reputation in the Garden State, its status as the number one online casino is perhaps no surprise.

It will, however, be interesting to see how the offering fares ‘away from home’, so to speak in Illinois, Michigan and West Virginia, three states in which Golden Nugget will expand its US footprint in the near future.

  • Biggest collection of casino games in NJ

BetMGM Casino

MGM has taken all of the experience and expertise gained from decades within the casino industry to produce a top online casino, at present, available for casino players in New Jersey, West Virginia, Pennsylvania, and Michigan.

A bumper collection of exclusive games, an array of payment methods, and the ability to play many of the games for free - quite an unusual approach compared with other online casinos - are all reasons why BetMGM is a popular choice of casino site.

An all-in-one gambling app that facilitates seamless switching between sports betting and casino games brings an added convenience for players looking for the ultimate online gambling experience.

Sports betting behemoth, William Hill has steadily grown into one of the most recognizable betting brands in the US. The British bookmaker has secured market access in over 20 states and is live with mobile betting in nine of those.

With decades of experience in the bank, William Hill is super reliable and about as trustworthy as sportsbooks come. A glorious selection of bets across various markets is perfect for the sports bettor who enjoys wagering on all types of sports and immediately removes the prospect of customers having to find another book.

Meanwhile, a straightforward and user-friendly mobile app without all the advanced features of competitors is in-tune with the no-frills type of bettor who just wants to place a bet without distractions.

Best of all though, Tropicana is operated by renowned casino software provider, Gamesys. The UK gambling giant is responsible for the creation of many of the best casino games, many of which are available at Tropicana and Virgin casino, the sister site to Tropicana in New Jersey.

Of course, though, any online casino site is judged by not only the quality of the casino games available but how many. Tropicana delivers in this regard too, guaranteeing all players can find the games they enjoy most. Players at Tropicana also have the opportunity to try out new games for free.

888 Casino

888’s award winning online casino is a staple of the US online casino market and has been active in New Jersey ever since online casino sites were first allowed in the Garden State.

The offering ticks all the boxes in terms of what a player wants and needs including a first-class gaming experience, a highly functional mobile app and a catalog of games packed full of slots and live table games - the site is especially good if online slots are your thing!

Most impressive is how 888 continues to look at ways to keep 888casino relevant and fresh for the modern day player. The company’s roll out of its own range of live dealer games in particular goes to show how and why 888casino has remained a favorite for casino players in New Jersey.

  • Brilliant choice of online slots

All of the experience gained as an online casino, 888 used to launch 888sport, the company’s sports betting arm in 2008. Having become an established betting brand in Europe, 888sport then expanded to the US ten years later, launching in New Jersey.

Like DraftKings, 888sport is also powered by tech provider, Kambi. This is a major plus in delivering the ultimate sports betting experience for US bettors looking to wager on hundreds of markets across various sports. The company’s European background meanwhile ensures you can bank on being able to bet on any sport or competition which takes your fancy, American or otherwise.

Live betting, a simple yet very effective interface, and a comprehensive stats section for the real betting nerds to tap into, are also factors why 888sport is winning many fans in the US.

Bet365 Sportsbook

It’s hard to imagine any sports betting market without Bet365, the largest sports betting company in the world. And though Bet365 is a lesser-known brand in the US as it stands, you can place a futures wager on this being the sportsbook that blows the competition away eventually.

Why? Well because it’s simply the best at giving the bettor precisely what he/she wants, without them being aware. The company first introduced live streaming for example which revolutionized the industry and set Bet365 apart from the competition - you could argue many are still trying to catch-up!

Despite its US footprint limited to just New Jersey at present, the British bookmaker is still growing in popularity in America. And as soon as Bet365 gain access to more markets on top of confirmed deals for Colorado and New York, you can see Bet365 challenging FanDuel and DraftKings for market leader status in many states.

Why Bet365 is so popular

  • Seamless online betting experience
  • Best betting site for live streaming
  • Huge range of markets and types of wagers
