Popular Real Money Casino Games

You can play hundreds of different games at the best US casino sites. Some game variants may only be found online. Let’s explore your online options for table games and slots.

American Roulette

American Roulette features a wheel with 38 numbered pockets – 1 through 36 plus the 0 and 00. You place wagers on where the ball will land. You can bet on single numbers (Straight Up), which pay 35/1. Columns and Dozens pay 2/1, while betting red/black or odd/even pays 1/1. The house edge of American Roulette is 5.26%.

Online casino sites usually let you bet on American Roulette for as little as $0.10, but high-roller variants are also available.

Best Online Roulette

In online roulette, you place bets on where the ball will land in a specially designed wheel. American Roulette is available at all good US casinos, but you can also find other variants such as European Roulette and French Roulette.

European Roulette and French Roulette boast a lower house edge too. The edge in European Roulette is around 2.7% as it has just one zero pocket. The edge is 1.35% in French Roulette. This is due to the “La Partage” rule. If you bet odd/even or red/black, and the zero appears, you receive half your stake back.

Online Baccarat

In online baccarat, two hands (the Banker or the Player) are dealt by the computer. You place bets on which hand will be closest to a total of 9, where picture cards are worth 0.

Each hand receives two cards. A third card may also be dealt, depending on the two totals shown.

Baccarat is available in a few variations online, including Mini-Baccarat and Punto Banco. It’s easy to play and you can play at low stakes.

Online Blackjack

In online casino blackjack, you and the computer receive two cards. You now have the option to receive more cards (“hit”) or “stand” and receive no more cards. The dealer then draws cards trying to get to 21 too. The aim is to beat the dealer’s hand or get a total nearest to 21 without going over (“bust”).

If you beat the dealer you win even-money. You win 3/2 if you hit a natural blackjack (an ace and picture card for a total of 21).

Online blackjack lets you place additional bets. You can double down on totals of 9, 10 or 11, or split pairs to create two unique hands. You can also take a 2/1 Insurance bet against the dealer holding a blackjack.

Online Live Casino

At online live casinos, you get to play real blackjack or roulette against a human croupier. The dealer is situated in a live casino setting or studio. They use special equipment which enables you to place bets on your computer.

In a live blackjack game, for example, the dealer uses barcoded cards that they scan as they are dealt out on a table. The cards appear on the screen, and you place bets as normal.

In live roulette, a real table and ball are used but a camera picks up the winning number and displays it on your video stream. The computer calculates winnings automatically after every game.

You can try online live dealer casino games at most US gambling sites. You will need speakers to hear the dealer and a graphics card to handle the live stream. You can even send messages to the dealer as you play. They will read the messages on their monitor and respond in real time.

Live dealer games:

  • Live roulette
  • Live blackjack
  • Live 3-Card Poker
  • Live Caribbean Stud
  • Live Casino Hold’em
  • Live Ultimate Texas Hold’em
  • Dream Catcher
  • Live Let it Ride

Real Money US Slots

You can play hundreds of amazing video slots and classic slot machines at good slots casinos . Choose from a 3-reel stepper with a few paylines or play for big stakes on a 5-reel slot with hundreds of win lines.

In online casino slots, you win money by matching symbols across horizontal paylines. You can also land wild symbols that act like jokers and help you complete winning combinations. Scatter symbols pay anywhere and will also help to trigger a bonus feature.

Bonus rounds can be as simple as a free spins feature, but new slots boast slick immersive bonus rounds with prize wheels, prize trails or win multipliers.

At an online casino, players can also take down a huge progressive jackpot. Progressives are formed with small portions of qualifying bets. Progressive jackpots may be linked across all participating casinos.

To win the jackpot, you may have to trigger a special bonus game. Usually, the more you bet, the better your chances of winning the big jackpot.

Many of the world’s biggest gambling software manufacturers are licensed to supply online slots in the US. Here are some of the leading US slots developers:

  • IGT
  • NetEnt
  • Bally
  • WMS
  • Scientific Games
  • Barcrest
  • High 5 Games
  • Everi
  • Lightning Box
  • Amaya

Are Online Casinos in the US Safe?

Safety and security are paramount concerns for US online casino players. You need to know that your games are fair and your money is protected.

Licensed casinos only support software from regulated providers. Before games reach the casino lobby, they are independently tested by approved gaming laboratories. Reputable casinos are also regularly audited by leading bodies such as eCOGRA and TST.

Fair online casino games are governed by Random Number Generators (RNGs). RNGs determine the outcome of every spin of the roulette wheel or deal of the blackjack cards.

Testing labs will audit RNGs over samples of thousands of practice games. Often, you can read audit certificates on the casino site. These display the average payouts being awarded by the casino for every type of game. If the payouts are too low, you know there is something wrong with the games.

Licensed US casinos will also protect players’ data. Online payments are protected by top-level encryption to prevent hackers. Funds will also be held in segregated accounts away from the casino’s operating budgets. This means that in the event of liquidation, your money is always safe.

In US states where online casino games are legal, gambling sites will always check that customers are allowed to play. They employ a security process at registration where you must supply proof of ID and proof of address. You may also have to supply your Social Security number (SSN) to verify your identity.





Online Casino Bonuses - What You Should Know

Most US casinos online will offer bonuses to players. To attract new players, casinos offer welcome bonuses. These usually include a deposit match and maybe free spins on selected slots.

Once you become a regular customer, you may get access to ongoing promotions such as a reload bonus or bonus spins. You can even join a loyalty program and earn free cash every time you play.

How do Online Casino Bonuses Work?

Most casinos offer some kind of bonus. They will award you with free cash if you meet the wagering terms and conditions of the bonus. Most times you will have to make a deposit to claim a bonus. However, there are lots of casino bonuses that require no deposit. Sometimes you will need to provide a bonus code to activate the bonus but often bonuses are automatically triggered for first-time players.

Types of Online Casino Bonuses

Welcome bonus: This is the most typical casino bonus you will find. It is awarded to new players only, and regular players will be exempt.

To claim a welcome bonus, you must make a deposit when you sign up. The casino will usually match your bonus 100%, but the amount can vary. You must then play enough eligible online casino games during your first 20-30 days in order to withdraw your bonus plus any winnings. Not all games count the same toward satisfying your wagering requirements, so read the terms carefully. Some casinos apply 100% of slots wagers but just 10-20% of table games, while others will count the play equally.

No deposit bonus: Some casinos also offer a new player bonus where no deposit is required. You can use your money to try out slots and table games. To withdraw the free cash, you must wager the bonus amount a certain number of times, typically 10-20 times over.

Free spins: New players can also receive free spins on a nominated slot. You can release any winnings from those spins once you have met the wagering requirements.

For example, you may earn 50 free spins when you sign up to a casino. Any winnings must be wagered 20-30 times before you can withdraw them.

Reload bonus: Regular casino players can also claim a regular reload bonus. This helps to retain loyal customers at the casino. The reload bonus works like a deposit match, but it will usually be smaller than a welcome bonus. You may only be able to claim 25-50% up to $100 or $200.

Casino Bonus Conditions and Wagering Requirements

As we have shown, online casinos in the USA don’t give away money for nothing. There are always strict wagering conditions to any casino bonus. We recommend you always read the terms and conditions before committing to any casino promotion.

Here are the four questions you need to ask yourself:

  • The minimum and maximum qualifying deposit
  • The time limit applied to the bonus
  • The size of the rollover requirement
  • The game eligibility percentages for slots and table games

We can’t stress how important it is to do your calculations before you start. At an online casino, a real money bonus may be so strict it’s impossible to clear. For example, you may only have a few days to clear the bonus, or the wagering requirement is so high you will never be able to gamble enough.

Some games might not be eligible, either. If all table games are exempt, for example, you will lose out if you want to play blackjack to clear your bonus.

Every casino bonus has wagering requirements. Here’s a good example of how a casino imposes a playthrough, or rollover, requirement to a bonus:

BONUS TOTAL: A casino offers 100% up to $500. You deposit the full $500. You now have $1,000 in total.

WAGERING REQUIREMENTS WITH BONUS: The wagering requirement is 20x the deposit amount. All slots contribute 100%, while table games and video poker contribute 20%. You have 14 days to clear the bonus total.

TO TRIGGER YOUR BONUS: To withdraw your bonus, you must gamble 20 x $500, or $10,000. You want to play roulette, but only 20% of eligible bets will contribute, meaning you would need to wager $50,000 in roulette to get the $500 bonus.

Bonus Abuse

As well as wagering requirements, the online casino will also impose strict bonus terms on how you can place your bets. To ensure fair gaming, the casino may annul your bonus if they suspect you of one or all of the following:

  • Placing single bets worth over 50% of your bonus total
  • Changing regularly between large bets and small bets
  • Withdrawing bonus cash immediately once it has cleared
  • Only playing low margin games (e.g. blackjack, craps, video poker)

What is the Sign-Up Process for Online Casinos?

It’s easy to open an account at an online casino. Players will need to be over 21 and you must have a valid, current home address. The registration process only takes a few minutes, and casinos also provide ways for you to upload sensitive documents.

Step 1: Click on the Sign Up button on the casino site. Enter your name, email address and date of birth.

Step 2: Create an account name and password. Your password must be hard to guess, so include a letter, number and symbol. You can also create a separate screen name, which is different to the username. This will be displayed on screen when you play games.

Step 3: Enter your Social Security Number. Most casinos only require the last 4 digits of your SSN.

Step 4: Enter your home address, including the state. The online casino may deny your registration if you enter an invalid address. At this point, you can also enter a welcome bonus promo code if you have one available.

Step 5: Once your registration is complete, you will have to verify your email address. You will be sent a validation email. Click on the link in the message to complete the verification process.

Step 6: Before you make a first deposit, the casino will need to verify your ID. You will be asked to supply copies of a photo ID like a US passport or driver’s license. You can also upload a copy of a government-issued ID.

You will have to upload a copy of a recent utility bill as well to confirm your residential address. This process usually takes 24-48 hours. Some casinos even let you upload documents via the live chat support window.

Depositing and Withdrawing at Online Casinos in the US

You can make a deposit as soon as your online casino account is verified. Depositing cash into your account is quick, and you can even save payment details for later.

In 2020, many US casinos still can’t accept credit and debit card payments because some financial institutions continue to block the transactions. It’s good to have one or two alternative casino payment methods ready when you want to deposit. Popular online casino real money banking options include:

VIP Preferred (ACH/e-Check): VIP Preferred is a third-party processor that lets you write virtual checks from your bank account. VIP Preferred uses the Automated Clearing House (ACH) for payments. It’s quick and safe, and there are no fees.

Play+/prepaid cards: Many casinos accept prepaid cards, and the Play+ card was created for exactly this purpose. You can sign up right after registering at the casino, fund it with a credit or debit card or bank transfer, and start betting. You can use one Play+ card at multiple casinos and withdraw winnings at ATMs.

PayPal/e-wallets: E-wallets are safe, virtual accounts where you can store funds online from multiple sources. Because e-wallet payments are anonymous, they are ideal for online casino play. PayPal, Neteller and Skrill are currently the biggest e-wallet providers accepted at US casinos.

Bank/Wire Transfer: Some casinos let you transfer cash direct from your checking account without using a card. Some fees may apply, but deposits are safe.

PayNearMe: PayNearMe lets you transfer funds in person with cash at your local 7-Eleven, CVS or Family Dollar store. There are fees associated with PayNearMe, but most regulated US casinos accept the payment method.

Debit/Credit cards: Major cards such as VISA and MasterCard are accepted at online casinos in the US. However, around a dozen US banks won’t process deposits for online gambling. It’s worth checking with your local bank to see if they will honor online casino payments. Card deposits are instant, and you can deposit from as little as $20 into your casino account.

Casino cashier: If you live near a land-based casino partnered with an online casino, you can deposit cash in person. Simply visit the cage at the casino and deposit USD. Your funds will appear instantly in your online account. You can also withdraw funds this way.

Check by Mail: You can also deposit gambling funds by personal check. Checks may take weeks to clear but you avoid having to use a card or bank transfer.

Making Online Casino Withdrawals

As long as you have funds in your casino account, you can cash them out to a prepaid card, e-wallet or bank account.

In general, debit and credit cards can’t be used to make withdrawals. Prepaid cards are a good alternative as they are accepted widely and you can use them to withdraw cash at an ATM.

Processing times: All casinos apply processing periods to cash-out requests. This is a 1-2 day period where the casino can perform the necessary background checks. It also gives you time to change your mind and reverse the withdrawal request.

Are Online Casinos Different from Traditional Casinos?

Online casinos couldn’t be more different than brick and mortar casinos. Here are three of the biggest differences.

A wider range of games: An online casino in the US might boast hundreds of slots and table games. Your nearest land-based casino may only have a handful of table games and a dozen slot machines. Online casinos can boast hundreds of slots and exciting table game variants you can only find on the web.

Casino bonuses: At an online casino, you can earn a new player bonus just by signing up. Regular promotions include reload bonuses, bonus spins and membership of a VIP program. Those benefits just can’t be found at a brick and mortar casino.

Higher RTPs: Many land-based casino slots are programmed with lower RTPs (Return to Player percentages) than online machines. Land-based slots may pay out 85-90% compared to 95-97% for popular online slots.

Faster games: Online casino games are quick, and you never have to wait for a space at the table to play. Because games move a lot faster, you can work harder to clear an online casino bonus.

Free Online Casino Games vs Real Money Casino Games

One major advantage of online casinos is that they offer both demo play and real money games. Here are some of the differences between the two types of game.

Risking real money: In demo play games, you never risk your own cash. The casino will give you play credits to gamble with. You can keep playing as long as you like. If you run out of credits, simply exit the game and re-enter via the lobby. You will be awarded more credits to play with.

Live dealer games: Not all online casino games have a demo play mode. Live dealer games are usually only available for real money, so you will have to make a deposit in order to play.

Winning progressive jackpots: You can try many online slots in free-play mode. Progressive slots will always have the progressive jackpot deactivated, however. There is no way to activate the special bonus feature that triggers the progressive.

Earning bonuses: To claim a casino bonus, you will have to play real money games. Even a no-deposit casino bonus must be claimed via real money slots and table games.

Slots RTPs and volatility: Online slots have different volatility. This is the frequency with which a slot pays out over time. Some free-to-play slots tend to be less volatile as there is no financial risk for the casino. The RTPs (Return to Player percentage) can also be higher in some demo play slots compared to real money games.

Offshore Online Casinos vs Regulated Online Casinos

In the US, there are two types of casinos you will find online: regulated casinos and risky offshore casinos. All online gambling enterprises must acquire a gaming license to operate legally in the US. Let’s examine the difference between the two.

Legal online casinos: Regulated casinos are properly licensed in the states where they operate. Only customers located within the state’s borders can play for real money.

Legal US casinos practice responsible gambling and have proper security checks in place. Funds are segregated and all financial transactions are encrypted.

Regulated online casino sites will only offer safe and fair slots and table games that have been properly audited. You can always be sure that the random number generators have been checked for fairness.

Legal US sites also boast a wider range of games. Software providers are licensed to supply games within the regulated state.

Offshore casinos: Offshore online casinos have their headquarters outside the United States. They still carry gaming licenses, but they are from jurisdictions like Curacao that don’t have the approval of US gambling regulators.

Offshore gambling sites can carry a lot of games, but typically they aren’t from software providers who have US licenses themselves. Offshore casinos acquire cheap licenses and run sites without the due diligence shown by regulated US operators.

To stay completely safe, only sign up with legal online casinos in the US. Your funds will be protected and you can be sure of a fair game.
