In 2021, five states have legalized online casino games. Although the American gaming industry is still in its infancy, you can participate in online slots, table games, video poker, and live dealer games in these four states. More states are set to join the legal gambling club in 2021 and 2022.

New Jersey

NJ online gambling was the first to legalize online casinos back in 2013. There are more than 20 online casinos and even more sports betting sites in the state. The best NJ no deposit casinos give players up to $25 for free, whereas the deposit match bonuses can go as high as $1,500. More than 1,000 online slots NJ are available at the best casinos.


Pennsylvania gambling is almost like NJ’s younger sibling when it comes to online gambling. With 10+ casinos live and more being added constantly, the future of PA online casinos looks bright. They also have some exclusive casinos like the Hollywood Casino Online.

West Virginia

West Virginia gambling is small, but they were the third in the country to legalize mobile casinos and sports betting. Although WV is a small market, the WV online casino industry has attracted the attention of some large players in the industry.


Michigan online casinos opened up on January 23rd 2021, and the Michigan gambling industry’s been growing rapidly ever since. The total gambling handle is closing in on Pennsylvania, and Michigan might well overtake PA by the end of the year.

⭐ Online Casinos in the US by Category

When it comes to online gambling, many of us have niche interests. Consequently, we offer detailed lists of American online casinos in three distinct categories – casino bonus, free spins, and legal sports betting. These sections make it easier for players like yourself to get the most out of your gaming experience.

  • Best US Casino Bonuses: BonusFinder lists legal American online casinos that offer the best casino bonuses. These include ongoing promotions as well as welcome offers. These deals change often, so check this site and New USA No Deposit Casinos 2021 page as well as the No Deposit Bonus Codes page.
  • Top US Free Spin Casinos: Online slot fans covet free spins, as they give them the chance to win untold sums of money. However, at this moment, American online casinos mostly hand out free cash instead of free spins. Convert them to free spins, and you can play 100 or 200 free spins – no deposit! You can find the offers easiest on our free spins page.
  • Best US Casinos For Online Betting: sports betting is the most widespread form of gaming in America today. While casino gaming mostly remains confined to NJ, PA, WV, Michigan, and Delaware, online betting is legal in states like Indiana, Illinois, Tennessee and Colorado. Many of these states have a mix of homegrown and international players, so the market is competitive in many states.

Mobile Casino Apps

It’s 2021. Consequently, most American online casinos offer mobile functionality to their players. Many sites have mobile apps, but even those that don’t are designed to work in mobile browsers. All websites we recommend work on both iOS and Android devices, as well as on rare ones like Blackberry and Windows Phone.

Mobile-friendly casinos can be found in America, so they offer functionality to all devices. If your phone can run a modern web browser like Google Chrome, you can play online casino games in America. Most online casinos offer mobile apps, but when a particular site doesn’t, their game software will work in your mobile browser just fine.

Most online casinos offer the same number of slots and casino games on mobile. They often have the same graphics, but with features that make gaming on a mobile device a breeze.

⭐ Types of Online Bonuses

Almost every casino in Vegas tosses out comps to keep their players happy. Similarly, the best American online casinos are no different. Here are the most common bonuses you’ll encounter at top US online casinos:

  • No-Deposit Free Money: In markets like NJ, competition is cutthroat. To attract players, NJ online casinos will offer bonuses if you sign up for an account. These are called no-deposit bonuses. While small, getting any amount of cash for free is amazing. The winnings are in most cases paid in site credits you can use to win real money.
  • Deposit Bonuses: This bonus is the most common online casino offer. In return for depositing, American online casinos will match your sum up to a set amount. For instance, a 100% up to $500 would give you a total of $400 if you deposit $200. If you’re after big money, providers like 888Casino offer thousands in bonus cash through their offers.
  • Cashback: Cashback is a loyalty scheme that pays you back a percentage of your wagers or net losses. For example, 10% cashback on monthly net losses of $500 would get you $50.
  • Reload Bonuses: Sometimes, US online casinos will dangle these deals when you lose your bankroll. Often, they reserve this arrangement for VIP members. But, sometimes, they’ll offer them as part of an ongoing promotion.
  • Free Spins: A popular bonus offer elsewhere in the world, free spins have yet to catch on in America. In time, though, we are confident they will make their debut here. Free spins are exactly what they sound like – they are spins on slot games that cost the player nothing. Money won can be awarded as bonus cash (with wagering requirements attached) or real cash (withdrawable.)

Wagering Requirements

Remember: every American online casino promotion comes with a bit of a catch. Wagering requirements are only the start – expiry dates and other conditions also apply. Wagering requirements also vary from site-to-site. Some sites impose 10x requirements, others 5x, and some only require you to bet through bonus funds once. You can find the best no wagering and low wagering casino bonuses from our site.

⭐ Types Of Casino Games At American Online Casinos

If you’ve gambled at real-world casinos before, you’ll be pleased by what American online casinos have to offer. The selection is excellent, the odds of winning are high, and with a little luck, you could win significant cash payouts.

Blackjack, roulette, slots – offer the experience of casino gambling, but from the comfort of your home. Software-based games not doing it for you? Many US online casinos are live dealer casinos. In other words, a real dealer, via a live stream, deals the cards, not an algorithm.

Casino Game Description
Online Slots Slots are easily the most popular game in any American online casino. Any decent site will have hundreds of titles and scores of variants to choose from. From classic 3-reel machines to games that offer 1,024 ways to win, the options are endless. Lastly, some slots boast progressive jackpots worth, hundreds of thousands, or even millions of dollars.
Scratch Cards These games are virtual versions of corner store scratch tickets. Dont balk at them – they are way better than their real-world counterparts. Lottery-issued scratch tickets only return an 65% of winnings to players. Meanwhile, American online scratch cards have RTPs as high as 95%!
Sports Betting From football to soccer, Americans love sports betting. Football Sundays and the baseball season get a whole lot more interesting with a couple of dollars on the line.
Live Blackjack Online Blackjack games offer some of thinnest edges online. In some cases, the house only has an advantage of 0.1%. In American online casinos, you find software-based and live dealer versions of the classic table game.
Live Roulette Available in software-based or live dealer versions. You'll find American and European versions in most US online casinos. At the eisk of sounding unpatriotic, we recommend European roulette over American. Why? Because American roulette has two 'zero slots' instead of one, which increases the house edge significantly.
Live Craps Who doesn't like hitting the Craps table? Craps at live casinos are not yet available, but with Evolution Gaming releasing Live Craps, you can hit the table right from your couch. That's perfect.

Golden Nugget has the most robust American live dealer casino. In it, there are 14 different tables to choose from.
