Online Casinos USA – Best USA Online Casino Sites 2021

The USA online casino market is the biggest market since it produces billions of dollars in revenue every year. Needless to say, everybody wants a slice of this highly lucrative pie.

In this piece, we focus on the USA casinos with licenses in Curacao, Panama, and Costa Rica. Long story short, they’re legal casinos that welcome players from the United States and from abroad. Therefore, casino gamblers from America can play their slots for real money, legally.

But, more importantly, the Federal Government states that online gambling is no longer against the law. So, if you’re one of those players that’s afraid to sign up and play, don’t be. The notion of gambling in your underpants might not be a pretty sight. But, it’s undoubtedly the reality and the future of gaming.

At onlinecasinos2.com we review the best casinos online for US players. Casino sites that offer legitimate games certified by independent third parties. Furthermore, the US casinos give new customers a bonus on deposit. They also take care of their loyal players by offering them comps, special bonuses, free spins, and VIP programs.

The best casinos for Americans cater to Millennials as well. Even though they’re the next generation of online gamblers, they’re an interesting bunch too. Classic casino games don’t interest them at all. Hence the reason slots studios now release skill-based games with a social element. Unlike mom and dad, they’ll never play classic games. Suffice to say, our best casinos online USA give these nascent customers exactly what they want.

Overview US Casinos Online

As we said previously we only advertise the best US sites at OC2. They’re casinos with licenses that list a variety of deposit and withdrawal methods.

Chief among them are cryptocurrencies like Bitcoin, XRP, Ethereum, and Bitcoin Cash.

Cryptos are cheap, fast and they make cross-border payments possible. Moreover, US casinos settle withdrawals within minutes up to 12 hours. We discuss this in more detail in the casino USA banking section.

Another thing casinos focus on is mobile casino gambling for USA players. Mobile phone technology disrupted the online casino industry by a country mile.

Players can now play their favorite casino game on-the-go. They also receive incentivized deals such as special mobile bonuses, free spins, and frequent player points.

The most popular software houses for American gambling sites are Betsoft, RealTime Gaming, and Rival. They offer players hundreds of casino games that they can download or access in their browsers.

Are the games safe at our top US casinos online? Yes, they are. A random number generator determines the result of each spin. We can then honestly say that the games are random and of course, safe.

US Casinos Bonuses, Promotions & Rewards

The size of the deposit bonus US casinos offer is between 100% to 500%. Generally speaking, they’re the biggest sign-on bonuses in the business. Players are also eligible for free spins and no-deposit bonuses.

To claim a bonus you must provide the code for it at the casino’s cashier. Moreover, you must deposit $30 or more before the casino credits your account with a bonus.

Note, before you can withdraw the money you won with the bonus you must clear the WR. Make sure you read the fine print attached to the bonus.

Players at our best USA casinos like it when they overstay their welcome. They can participate in daily promotions where they cash in on free spins, a Bitcoin bonus, and reload bonuses.

As far as the comps go. US casino sites online reward players 1 comp for every $10 they wager on slots. If you accumulated 100 comps over a few sessions.

The casino will exchange them for $1 in hard cash. Furthermore, casinos online in the US offer cashback of up to 20% on player losses. They, therefore, model their rewards structure around the more you play the more we pay.

Next in line is the casino’s high roller VIP program. The moment you deposit and play a casino game with real money you start earning comps.

The more comps you earn the higher your VIP standing at the casino. VIP members have certain benefits. They can withdraw bigger cash amounts. They receive special bonuses and a VIP manager looks after them well.

Banking At Casinos Online USA

In the case of U.S online gaming; the car in question is the ease with which the player can fund his online account. Initially, getting player funds in and out of a USA casino online was a big problem. If players can’t fund their accounts they can’t play.

In addition, American banks won’t touch anything that relates to the Unlawful Internet Gambling Enforcement Act of 2006. Most US banks took a blanket view to avoid unnecessary exposure.

The Justice Department’s reinterpretation of the Wire Act in 2011; gave the gambling industry and banks more insight into the UIGEA.

The broader understanding was that online gambling wasn’t as illegal as everybody thought it was. On the condition, it did not involve sports betting.

The US banking industry’s relationship with online casinos is spotty at best. In an ideal world, players must be able to fund their casino accounts with a variety of methods. Luckily, online US casinos in offshore regions successfully address this problem.

Different Deposit and Withdrawal Options

usa mobile casinos

Players can now deposit and withdraw with Bitcoin, XRP, Bitcoin Cash, Ethereum, and Dogecoin. The de facto currency is USD$ but they also accept Euros and British pounds. While deposits at our best online USA casinos are instant.

Give or take a minute or two for BTC. Cryptocurrency payments go out within minutes at best up to 12 hours. They also accept fiat currency banking options such as Bank Wire, Check, and MST Gift Cards. The weekly withdrawals at American casinos range from $BTC2,500 up to $BTC15,000.

However, this depends largely on the player’s status at the casino. As VIP casino high rollers can withdraw more money.

US casinos are streets ahead because fiat currency banking is archaic by now. Unfortunately, the banking industry is not paying as much attention to the gambling industry as we are.

 

Is It Legal To Gamble At US Offshore Casinos?

Yes, it is. First, because the Federal Government doesn’t ban online gambling. Secondly, online casinos US that operate offshore have licenses. As such they’re legal, but before you can play at them you must be at least 21 years old.

 

Casino Software American Gambling Sites

Betsoft Gaming, RealTime Gaming, Saucify, and Rival are the best software providers for casinos USA online. They list hundreds of casinos which they divided into slots, table games, progressives, video poker, and specialty games.

The majority of the games at our best casinos US are online slots. They boast a variety of themes, with colorful visuals, large jackpots, high RTPs, and plenty of bonuses. It’s not only slot machines that grace their virtual lobbies.

Table games like blackjack, craps, baccarat, red dog and pai gow poker do too. Bets per hand start with a few cents up to a few thousand dollars.

Moreover, they sport video poker varieties like Aces and Faces, Jackpots, or Better and Deuces Wild. Gaming on the go is the next big thing, to be more specific mobile online casino gaming.

As long as players have the Internet and a mobile phone – they can gamble from anywhere. The other “less popular” games on the list are bingo, keno, and scratch cards.

Live US Casino Gambling Online

Live casinos have been climbing the casino ladder steadily the past year. Thanks to Evolution Gaming, US players can now play live baccarat or roulette against live dealers for real money.

Play occurs in real-time which means the live casino mimics a real casino environment. It’s social gaming at its best less all the distractions that occur at brick and mortar casinos. Players can chat to the dealers or to fellow players if they wish. The USA live casinos is the best of both worlds.

Moreover, instant withdrawal live US casinos allows players to engage in low-cost games with a high turnover.

 

Player Support

The hallmark of any successful casino operation is its customer support. The good news is that the best casinos online treat their USA players like royalty.

By this we mean, players can reach them at any time through email, live chat, or telephone. Some of them offer an online form that you must fill out.

Live chat is only available during certain hours but email support is on standby 24/7. US gambling sites provide a FAQ section.

To get a snapshot of the casino’s operation please go through it. They address common player questions such as banking, how to claim a bonus, and so on.

Yes, they are. There are two types of online casinos that target American casino players. The first is casinos that have a legitimate license in offshore regions such as Curacao, Panama, and Costa Rica.

The other type of American casinos is the ones that have licenses in US states like Delaware, New Jersey, Nevada, and Pennsylvania.

At onlinecasinos2.com we cover the most secure USA casinos. They list plenty of download and instant play mobile casino games. We categorize them in terms of their games, bonuses, perks, withdrawal times, reputation, and support.

Absolutely no. At least the casinos OC2 promotes don’t. We play slots for real money and we can vouch that their games are safe.

Unfortunately, there are online casinos that cheat their players. It can be through dodgy games, top-heavy bonus terms, or not paying player wins.

The best casino games are slots for real money and video poker. Slots have RTPs of 94% to 98% and video poker up to 99%. If you play blackjack make sure you know the basic strategy. As it reduces the house edge to -054%.

Sweepstakes casinos use the sweepstakes cash model and they’re in every state. Players buy virtual coins that allows them to play casino games for real cash online.

No, it’s not necessary. You can play slots, table games, video poker, or progressive jackpots on your mobile phone’s browser.

Yes, they do. Players can self-exclude themselves for a period to permanently from the casino. Casinos enable players to set their own deposit and session limits. They also use phishing software to prevent minors under the age of 18 from gambling. The min age to play at USA casinos is 21.
