5 Best USA Online Gambling Sites 2021 Reviewed

America’s love affair with online gambling is still in its early stages, and yet already there are more casino sites and brands in this marketplace than you can reasonably be expected to try out for yourself.

If you are struggling to choose a legitimate online casino operator, this overview of the best sites around at the moment will point you in the right direction. Online Casino Snoop is a great source to start your search.


Consistently ranked among the top US online casinos & sportsbooks reviewed here, BetRivers is a reputable brand which provides all sorts of games, gambling opportunities and services.

Its website is slick and easy to use, with a straightforward interface that should not be too confusing for newcomers to get to grips with. There are also plenty of different experiences available, from classic casino games and online slots to sports betting that even includes esports events.

A solid deposit-matching bonus for first timers is also available, so you can get up to $250 of free cash to use on the site as you are getting started. The only downside is that because it is not as well known as some of the other brands in this list, it might not have the same recognition with all players, which might put you off.


Another up and coming online casino brand, UniBet has the advantage of being especially focused on sports betting, which could give it the edge if you are mainly interested in this kind of gambling activity.

Of course it would not be able to earn a place in this line-up if it was not also capable of catering to customers with other tastes, so you will find plenty of digital casino games including video poker and a healthy dose of slots.

New customers can claim a $10 free play reward even if they do not deposit any cash with UniBet, which makes it an excellent no-risk option if you just want to take an online gambling site for a test drive. Then if you do decide to commit, you can get a 100% deposit matching bonus worth up to $500 courtesy of this site right now.


When it comes to being well-known, it is hard to top MGM in the casino world, and its online gambling service is undeniably up to the task of meeting and even exceeding expectations for customers who have visited its land-based venues.

In fact with BetMGM you can even replicate the real-world casino experience thanks to the large number of live dealer games which can be played. These let you enjoy table games like blackjack, roulette and poker with a human host responsible for orchestrating everything, which is a nice touch.

The generosity of BetMGM’s new customer bonuses should also be celebrated. Deposit matching up to a value of $1,000 is on the cards as we speak, although of course you will need to read the terms and conditions to make sure you are eligible for this kind of offer.

Caesars Casino & Sportsbook

Another name you will no doubt recognize from the bricks and mortar casinos that have made it famous, Caesars is an old hand when it comes to handling online services as well. So if you are looking for a resilient and reliable casino platform, then you will find it courtesy of this venerable operator.

A $10 no deposit bonus follows in the footsteps of the risk-free offer found at UniBet, and we definitely recommend taking advantage of this even if you do not plan to play on the site regularly, because there is nothing tying you down to it if you go this route.

Aside from the bonuses, Caesars also has plentiful slot games and sports betting opportunities for customers. It is also a popular place to play poker online, which could sway you if this is your preferred skill-based card game.

Sugar House

Sitting pretty at the bottom of the list, Sugar House is still very much worthy of your attention thanks to its impressive mobile application, which is a quick, slick way to enjoy slots, casino games and sports betting while out and about.

You can even get access to its live dealer games from the app, or of course you can stick to playing on your laptop or desktop machine instead; the choice is yours!

Regardless of the online casino site that grabs your attention, remember to only play with legitimate operators and adhere to the rules that apply in your state when it comes to web-based gambling.
