Why Play Real Money Casinos Online?

Nothing can match the fun and excitement of real money casinos. Here are just some of the benefits of gambling for real cash at great online casinos in 2021.

Win Real Money at Home

With online casino sites, you can play for real cash and win jackpots in the comfort of your own home. There’s no need to travel miles to a brick-and-mortar casino and you can even play through your smartphone or tablet.

Choose Stakes to Suit Your Wallet

Most land-based casinos have high minimum bets on slots, roulette and blackjack. However, USA online casinos will let you play video slots, video poker or table games for just a few cents.

Play a Wide Range of Games & Slots

Online casinos give you an enormous choice of video slots and games. Whatever your taste, there’s a game for you. Select old-school Vegas slots or the latest multiway video slots with big bonus round and progressives. You can also try out live dealer games with stakes starting at just a dollar.

Enjoy the Best Promotions

You can access some top casino promotions when you play for real money. Play online casino games and earn loyalty points which can be redeemed for real cash. Plus, you’ll be able to enjoy regular reload bonuses, free spins on new releases, or join a slots leaderboard challenge.

Try Free-Play Before You Buy

The best online casinos will let you test out games for free before you commit real cash. Try a new slot or an unfamiliar table game and see if it’s worth risking your own hard-earned bankroll.

US Casino Apps vs. Desktop Playing

All good US online casinos offer a mobile app that lets you play slots and games on the go. Install a native app through the casino or visit the App Store or Google Play. You’ll need a recent smartphone to access games, but playing is as easy as logging on and tapping on your favorite titles.

Mobile Casino AppsOnline Casino Desktop Play
  • Use GPS and WiFi to pinpoint your location
  • Play slots and table games specially designed for your device
  • Use mobile payment options such as Apple Pay and BOKU
  • Enjoy games that utilize a bigger desktop screen
  • Access the best online casino gambling promotions directly through your phone
  • A wider range of games are usually available
  • Install geolocation tools to ensure you’re playing legally within state borders
  • Use your debit card, e-wallet or prepaid card to deposit
  • Excellent touch-screen slots and table games
  • Claim a welcome bonus or join a loyalty program
  • Funding Your US Casino Online Account

    You can fund your account at the best online casinos via a wide range of banking options. Use an approved US debit card or load a prepaid card if one is available. Always be aware of any fees that your bank or the casino may charge.

    In addition, you will be able to make withdrawals from your online gambling account back to your checking account or e-wallet. Processing can take a few days and fees are normally waived.

    Other Payment Options at US Online Casinos

    There are a few good alternative payment methods to use at the top real-money online casinos. Some rely on cash in person, which can be a great option if you don’t want to pay online.

    Some casinos let you pay in person at the cage. That’s great if you live close to the partner casino. Just rock up and make a cash deposit at the casino cage. Your funds will be deposited into your online gambling account within 30 minutes.

    Alternatively, you can make cash payments at your local 7-Eleven by using PayNearMe. Deposit up to $500 in cash and provide your online casino account details. It’s as easy as that.

    Top Games at Online Casinos in the US

    The best online casinos spread an eye-watering range of games. The variety is oftentimes much wider than you’ll find at a brick-and-mortar casino too. In addition, minimum stakes can be very low, as little as $0.01 a spin.

    But there’s still enough action for the high rollers. Many of the best online casinos in the USA will offer VIP rooms where you can play for up to $5,000 a hand.

    Online Slots

    Slots dominate the lobbies at real money online casinos. You’re bound to find way more online slots at casinos than any other game. Choose from classic 3-reel slots like you’ll find in your nearest casino, or test your mettle on the big-money progressives. In between, there are the latest branded games from NetEnt, High 5 Games or SG Gaming that are filled with bonus features and great graphics.

    Jackpot Slots

    Any self-respecting online casino in the USA will have at least a few progressive jackpot slots. Progressives are linked jackpots that increase the longer they go unclaimed. Jackpots can be triggered at random or by playing a special bonus game. In some cases, progressive jackpots can eclipse the million-dollar mark.

    Blackjack

    Online blackjack looks and feels like the real-life casino favorite: try to reach 21 without going bust and beat the dealer’s total in the process. You can win 3/2 for a natural blackjack too. Plus, many top online casinos spread interesting blackjack variants with side bets and special rules.

    Roulette

    Online roulette is easy to play and most of the big game developers provide at least one variant. Try familiar American Roulette with its 00 pocket or go for a lower house edge in European Roulette and French Roulette. The beauty of online roulette is that you can play at very low stakes – perfect for the casual gambler.

    Video Poker

    Most of the video poker games at USA casinos are provided by IGT. Select your stake and get dealt five cards. It’s up to you to hold or change cards to try to make the best 5-card poker hand. The better your hand, the more you win. You can even bag a jackpot by hitting a Royal Flush when playing the maximum stake.

    Baccarat

    Baccarat is easy to play and offers one of the lowest house edges around. Bet on which hand — the Banker or Player — will have the highest hand total closest to 9. You can also win on the Tie. Baccarat is offered in computerized and live dealer forms.

    Craps

    Craps is known across US casinos for its party atmosphere and big gambling action. Online, you get to be the shooter and roll the dice to determine the Point. Then, bet on which numbers will be rolled next. You can even play in Demo Mode to get accustomed to the rules first.

    Novelty Games

    Most online casinos offer a selection of alternative games. Keno is the casino favorite that pays out when you match as many numbers as possible. Also, look out for instant-win "scratchers" and fast bingo games where you can win a jackpot for filling the full house.

    Casino Bonuses to Look For

    The best real money casinos will offer a steady stream of bonuses and promotions. Start off with a welcome bonus, then follow up with a reload bonus, bonus spins or VIP program. The top gambling sites will keep you up to date with the latest deals so you don’t miss a thing.

    Welcome Bonus

    A welcome bonus is reserved for new signups and tends to be the biggest deal in town. Just open your account and make an initial deposit to claim the promotion.

    The casino will match your deposit with bonus funds which you can use on eligible video slots and table games. You can unlock any winnings – plus the bonus cash itself – as long as you meet the casino’s wagering requirements.

    Free Spins Bonus

    Many welcome bonuses at online casino websites include free spins on slots. Use your free slot spins on a nominated slot and claim your winnings as long as you meet the wagering terms. Free spins are normally given at set stakes, so the total you can claim can be fairly small.

    No-Deposit Bonus

    Some US online casinos award a little free-play cash for you to use before you make a deposit. Use your free cash on eligible games of your choice and wager your winnings a few times over before releasing them.

    Reload Deposit Bonus

    A reload bonus normally follows an initial welcome bonus. It guarantees a deposit match of around 25–50%, and the maximum deposit amount will be limited. However, if you’re experienced in working off deposit match bonuses these deals are recommended.

    Loyalty/Reward Programs

    All good online casinos will run some sort of loyalty scheme. You accrue player points every time you gamble on slots and table games. The more points you earn, the higher up the loyalty ladder you can climb.

    You can also redeem points for cash or enjoy benefits such as faster cashout times. You may also be able to get access to a personal manager who can award bespoke promotions.

    Understanding Playthrough Requirements

    Most casino bonuses will feature some sort of wagering requirements. These are the conditions you must meet in order to unlock any bonus cash plus your winnings.

    For example, imagine a casino is offering a 100% deposit match bonus up to $1,000 with a 50x wagering requirement. That means the casino will match your $1,000 with $1,000 in bonus funds. To unlock your free $1,000 plus winnings, you must first gamble $50,000 (50 x $1,000).

    In addition, casinos will apply eligibility rates to certain games. For instance, slots may contribute 100%, while table games and video poker may only contribute 20%. You need to factor this in when deciding which games to play.

    Online Casino vs. Land Based Casinos

    The US now boasts the best in online casino betting and land-based casinos. However, only a handful of states offer both. So, which should you go for and what the benefits of land-based casinos vs online casinos?

    Land Based Casino vs. Online Casinos: Pros and Cons

    A big debate looms over which is better: land based or online casinos? The answer is subjective; however, its safe to say, online casinos are taking the lead.

    States With Legal Online Casinos

    Online casinos are now perfectly legal in many US states. Some states even offer a mix of legalized online sports betting and poker alongside casino games. Remember, you can join up with regulated online casinos anywhere in the USA. However, you will have to be located within those states to be able to log in and play games for real money.

    Michigan

    Michigan joined the party with legalized online casino gambling back in 2019. In one fell swoop, Gov. Gretchen Whitmer put pen to paper on blanket gaming laws regulating casino games, poker and sports betting. Some of the biggest casino players are already making inroads into the regulated market in MI.

    New Jersey

    New Jersey was the first US state to legalize online casino games. The home of Atlantic City now boasts some of the best internet gaming anywhere in the US. Join up with major players such as Golden Nugget and Borgata and make deposits in person at partner casinos in AC.

    Pennsylvania

    Pennsylvania legalized casino gambling back in 2017. It’s now legal to log on to a licensed PA casino and play slots and table games. Plus, many of the state’s biggest gambling players such as BetMGM, Caesars and Unibet are open for business.

    West Virginia

    West Virginia officially started regulating online casino sites in 2019. At the same time, WV legalized sports betting and online poker. Some of America’s largest operators wasted no time in opening online casinos, including BetMGM, DraftKings and FanDuel.

    Delaware

    Delaware was one of the first US states to legalize online casino games. However, since Delaware passed its first laws in 2013, the industry had been slow to move on. Most of the state’s regulated gambling sites are run by the same operator – 888.

    US Casino Regulation

    The USA still has no federal law legalizing online casino gaming, so it’s come down to individual states to pass their own laws. New Jersey, Nevada and Delaware were the early pioneers back in 2013 with a mix of online poker and casino games. Since then, several other states have joined the party.

    While individual state laws differ slightly in regards to casinos, there are some clear similarities. Online casinos must be partnered with an existing brick-and-mortar casino or racino, if one exists. Plus, gamblers must be aged 21 or over to open an account and be physically located within the licensing state.

    Under each state gaming law, gaming commissions or state lotteries are responsible for issuing licenses and ensuring due diligence.
