The best casinos in the US

What’s the Best Online Casino in the US?

Whilst the market is restricted, some of the renowned land-based casinos have opened their own online casinos so that they can cater to players who prefer to play without visiting the casino in person.

Due to the fact that the gambling legislation differs from one state to another, it is very important to check whether the casino you would like to play at accepts players from the state you are in. for example, there are several casinos that allow USA players to open an account however the players need to be within a particular state border to place wagers.

Remember, on CasinoTopsOnline, we don't publish casino reviews of illegal operators, such as Bovada, Las Atlantis, Cafe Casino, and El Royale. There are blacklisted online casinos and we don't offer them to US players.

The concept of fantasy sports has been around since the sixties and has evolved with technological advancements throughout the decades.

Each contest comes with an entry fee of as little as $1 and could go up to $10,600 and its own prize pool.

Monkey Knife Fight USA

Monkey Knife Fight (MFK) entered the scene in late 2018 and its different take on traditional daily fantasy sports quickly put traction amongst players. Unlike picking a line-up of athletes whilst respecting the pre-set salary cap, the main point of MFK is to see whether a player will go over or under a predetermined benchmark. Monkey knife fight comes with an attractive welcome offer consisting of a $50 match deposit bonus.

  • Payment methods accepted: Visa, Mastercard, Discover;
  • Win rate: 96.04%;
  • Support: Live chat, email.

United States gambling laws

Gambling Regulations Within the US

Due to each state having its own state laws and is governed differently, you might find that it’s illegal to gamble in the state you live in, while your neighbouring state is free to do so. Therefore, it's important to determine whether you're in a region that permits gambling online. Due to these restrictions, some online casinos have banned US players entirely.

When it comes down to USA online gambling laws, we have seen states allowing a bill that makes gambling, sportsbook, or online gambling completely legal in order to drive tax revenue back into the economy. Tax revenue is the biggest driving force behind passing bills that legalize all forms of gambling.

Because each state acts as a sovereign entity, it is entirely up to the state in question whether it wants to legalize online gambling or other online gambling activities. While states have control over their own regulations and legislation, federal laws still reign supreme over state laws, making it difficult to navigate the landscape for punters. There are three acts that fall under gambling federal law that are of importance:

  • The Federal Wire Act of 1961;
  • The Professional and Amateur Sports Protection Act of 1992 (PASPA);
  • The Unlawful Internet Gambling Enforcement Act of 2016.

These three federal laws do not strictly prohibit gambling and online gambling, but rather put major restrictions on the act. Aside from Utah and Hawaii, every state does have some form of gambling. Land-based casinos are legal state-wide within Nevada and Louisiana, while other states must rely on Native American casinos or racinos (a horse racing track with a slot parlour).

Only recently several states have moved towards making online sports betting legal. With that in mind, here at CasinoTopsOnline we only list American online casinos that have been regulated within each respectable state by its legislative body in order to be compliant with each state's laws.

Federal Wire Act

Originally, having the main objective of hindering fraudulent bookmakers and organized crime, the federal wire act was passed in 1961. The law prohibits the communication of sports betting-related information over wire communication (at that time mostly telephone and telegrams), but now it also includes the internet.

The law also prevents businesses (legal or illegal) from receiving any funds or profits gained from sports betting services. This was effective against underground bookmakers and organized crime gangs, cutting off a major source of their income.

The law itself only concerned itself with sports betting until recently. In 2018, the US Government issued an opinion to change the federal wire act to cover all betting and gambling solutions such as online poker, online lottery, scratch cards, online keno, online red dog, and online gambling. While nothing is set in stone, it does create some instability within the iGaming industry.

Professional and Amateur Sports Protection Act

The Professional and Amateur Sports Protection Act of 1992 (PASPA) is a bill signed by George W Bush that prohibits new laws in favour of online and offline sports betting. PASPA was created to stop the spread and popularity of sportsbooks throughout the United States.

When the bill was signed, Delaware, Montana, Nevada, and Oregon were made exempt because the bill did not state that any existing sports betting regulations needed to be abolished.

Rather, the PASPA bill prevented new laws from being made that could potentially legalize sports betting. In 2018 the PASPA bill was struck down in the supreme court through the sheer effort made by the state of New Jersey. The Supreme Court declared the bill unconstitutional on May 14th, 2018, paving the way for other states to legalize sports betting.

Unlawful Internet Gambling Enforcement Act

Now, the recent Unlawful Internet Gambling Enforcement Act (UIGEA) is an anti-gambling law that was passed in 2006. The law does not specifically state that online gambling itself is illegal, but rather the transactions made to deposit funds into one’s online casino account. Without funds, you cannot gamble, which effectively renders it impossible to play at any domestic or offshore online casino.

The law is not limited to cover just a player’s online casino account, but it also prohibits the funding of accounts at any fantasy sports and skill-based games providers. This meant the complete obliteration of the US poker scene and Daily Fantasy Sports fanbase, much to the dismay of players. Currently, more states are looking into abolishing the UIGEA law in order to bring in tax revenue and allow punters to safely gamble under supervised regulations.

US states which allow online gambling

US States Allowing Online Gambling

Currently, there are four states that allow online gambling within a regulated market and accept real-money bets and wagers. These states include Delaware, Nevada, New Jersey, and Pennsylvania. While online gambling within these states still comes with more restrictions and rules than what European players have to abide by. In the past few years, there has been a massive breakthrough in giving USA citizens the choice to gamble freely, which is a trend only likely to continue.

There are several states that are in the process of loosening the laws surrounding online gambling and sportsbook. This not only gives power back to the players, but it will also create thousands of new jobs within the industry and millions, if not billions, of dollars in tax revenue.

We've made a small list of what's allowed and where. Keep in mind that in some locations you may need to register at a physical casino. We'll update this when states have made any changes to their legislation.

US casino games and promos

USA Online Casino Bonuses

When choosing an online casino, it is vital to check the bonuses and promotions that are currently running. Most casinos also offer bonuses specifically for slots casino games, table games, and even sportsbooks so make sure that the casino bonuses are suited for your preferences.

Some casinos also offer bonuses for high rollers i.e. those people who don’t mind the wagering requirements of larger amounts of money, and while such bonuses require a larger input, the cash out is expectantly much bigger. It is always recommended that you stick to your budget and spend the amount that you can afford.

It is important to note that all bonuses and promotions have terms and conditions and any failure to comply will result in cancellation of the bonus and any winnings from the online casino bonus will be voided. Some casinos also require the players to input bonus codes for the casino offers to be activated.

There are two categories of bonuses that casinos may offer; bonuses that require a deposit to be made with one of the many payment options, and bonuses that players can opt-in for without making a deposit. Each category comes with different types of bonuses, which will all be explained in more detail below.

US Online Casino Games

There are two types of online casino games that are very popular with American players: slot machines and table games. All top online casinos offer such staple games and most also have dedicated sections on their online casino gambling site so that there is a full variety for all types of players.

Online slots come in various types include the simple classic slots casino games that provide you with a trip down memory lane, to the exciting multiple pay lines video slots! For those who wish to try their luck in winning real money progressive jackpots, you can find a variety of fixed and progressive jackpot slots in the game lobbies of most casinos. 

A leading online casino website would also offer the opportunity to play a variety of table games Including the classic blackjack, roulette, baccarat, and poker online. Some casinos also offer the opportunity to experience playing at a land-based casino from the comfort of your home by providing live dealer casino games. Live casinos are becoming more popular as they allow players to interact with the dealer as well as other players at the table.

One should note that some casinos have a significantly smaller section for table games as opposed to the super slots game section. So, if table games are your preference be sure to sign up for a casino that can tailor to your needs.

US Online Slots

US Table Games

Some games like three card poker and a bunch of others cards games may not be popular in European casinos, but in the US, this game is a thing. Let's see some of the choices you can find in the American online casinos.

New Sweepstakes Casinos in the United States

The United States brought a few changes to the policy of the contest, when new anti-lottery laws introduced by the Federal Trade Commission, resulted in refined US broadcasting laws. The laws stated that the participants do not need to make any sort of purchase or payment to enter the contest. It was emphasized that making any sort of purchase would not increase the participant's chances of winning. Many companies that started online sweepstakes used to forego the law and would only state that no purchase is necessary to enter the contest, without mentioning the rest of the law.

If you are a resident of the United States, you might also be familiar with office traditions surrounding sweepstakes. They are often referred to as 'pools' and are generally based on some huge sporting events like the Grand National or the World Cup. To enter the contest, the individual needs to pay a stake that is equal for each of the horses or teams before they can draw out of the balloting tool well before the event itself. If the individual wins, they can take the pot. As for horse racing events, the whole sum can be split between the winner horse and runners-up until horse number 3.

Banking Methods

Before signing up to a casino, have a look at the accepted payment methods and check if the casino accepts USD payments. It is also important to check for any hidden fees from certain payment methods. You can find such information on both the casino’s and the payment service provider’s sites. Not only the list of deposit methods has to be considered, but also if a casino offers fast payouts.

Customer Care

It is important that a casino has an accessible customer support team. Top casinos usually offer 24/7 customer support so that any queries are dealt with immediately. Options for contacting a casino consist of a contact form, live chat, phone number (could be toll-free for certain states), and email.

Payment Methods in the US

When playing at a real money online casino, it is very important to check that the payment methods offered are secure. One of the main issues American players face is the fact that major credit card providers are not willing to process payments if they are for online gambling purposes. This is most problematic for those players living outside of the states that have been regulated very recently.

A top real money casino would have several payment methods available, such as e-wallets. Remember, some methods, such as Bitcoin, are not very common as banking options within the USA. In general, gambling with cryptocurrencies is not allowed. Popular payment methods offered by casinos for real money play that can be used by USA players include:

  • Online Casinos With PayPal

Final Thoughts on US Online Casinos

The future for an online casino within the United States seems very promising. Although there are many different hurdles to overcome, and the federal government does not seem lenient towards paving the way on its own, we will have to rely on individual states to make a change. New Jersey has already set an example by fighting for the removal of the PASPA bill in 2018. 

Within every single state, there is some form of talk about loosening the restrictions on all forms of gambling. A lot of hesitation comes from the fear of an increase in players experiencing problem gambling. However, if the market becomes regulated and legit casinos have to apply for a license in order to operate, it will create a much safer environment for us players.

This means that US players will be shielded from unsafe online casinos, can set deposit limits for themselves, and can even self-exclude themselves for several months and up to 5 years. There are many different methods that allow the player to have control over how much they gamble and how to do this safely.

Follow our tips to improve your gambling experience.

Do US online casinos give out bonuses?

Yes! However, you must be located in a state that the online casino is licensed in to be able to play with real money. If you are not located in Nevada, New Jersey, Pennsylvania, or Delaware for a casino licensed in one of those states specifically, then you can only play for free, without real money.
