Most Popular Games at Online Casinos

Of course, whenever you are looking for an online casino, one of the biggest attractions is the variety of casino games that are at your disposal. These are the most popular games at online casinos across the United States, and if an online casino does not have these games, you might want to keep looking around.

You could definitely argue that online slots is the most popular game that you’ll find not only at online casinos, but at land-based casinos as well. With improved technology, you are no longer playing classic 3-reel slots (although they are still an option). 5-reel slots, 243 Ways to Win slots, video slots, progressive jackpot slots….they’re all here. Just make your bet, spin the reels and away you go!


Poker grew exponentially online when internet qualifier Chris Moneymaker won the World Series Of Poker in 2003. Now, there are entire online poker rooms in existence, and there are a slew of different variations of poker which players can dig into, such as Texas Hold’em, Omaha and Pai Gow. There is even some video poker if you would like to check that out.


Blackjack, or “21”, is the age-old game of trying to get to a total of 21 and beat the dealer, who also aims to reach a score of 21. There are far more variations of it online, where you can play Spanish 21, Atlantic City blackjack, Pontoon and many more.


Roulette is another popular offering at online casinos. You’ve seen it before: throw the ball in the wheel, make your bet (red or black, even or odd, and more), and let the ball land where it may. Check out the differences between American roulette, European roulette and French roulette, all of which you can play at online casinos in the USA.


Play James Bond’s favorite game as baccarat looks complicated, but it really has three outcomes: you win, the banker (dealer) wins, or there is a tie. Nice and easy, with variations such as Punto banco and Chemin de fer, which you can find online.

Live Dealer Games

Live dealer games are a modern approach to online casinos in the USA. You can play all of the casino games you would normally play, like blackjack, roulette and baccarat. However, you are playing along with a video feed of a real-life dealer, who you can interact with like you would at a land-based casino.

Online Casino Strategy

There are lots of different strategies for being successful at online gambling, especially for each game. Some games (roulette) can be more complex than others (slots), so it is a matter of figuring out what your favorite games are and adapting specific strategies to those. However, there are a few concepts you should put into practice, regardless of what online casino games you are playing.

Bankroll Management

We cannot stress this enough, and you will see it elsewhere on this site. Bankroll management is the #1 way to make your time playing at online casinos in the USA as enjoyable as possible. Simply put, don’t play with more than you can afford. That also means, don’t chase losses with even larger bets.

Play The Online Casino Games That You Know

This is another aspect of the game that players, especially novice players, tend to overlook. Stick to playing the games that you really know, or at least do the research to get familiar with the game before you starting betting real money on it. If you don’t know the first thing about slots, for example, you can read one of our gambling guides, which we have for most of the games that you will come across. Or, read the Help section of the game, which will give you a foundation to start off from. Also, if you can play a game for free first, to help you learn the nuances of the game, you should absolutely do so. Many online casinos in the USA allow you to play casino games for free first.

Look for the Best Bonuses

Online casinos in the USA are well known for enticing their players with excellent casino bonuses, from welcome bonuses to reload bonuses, from cashback bonuses to free spins and entrance to a lucrative loyalty program. There are even no-deposit bonuses, which are rare, but can really come in handy. Our online casino reviews will point you towards the casinos with the best bonuses that you can use to make your hard-earned American dollars stretch as much as possible.

Online Casino Bonuses

Speaking of bonuses, we can’t underestimate how important these are to both the player and online casinos in the USA. It allows the casinos to show off their services and attract players of all experience levels. Meanwhile, it gives the players a little more money to spend, which they can then use to play whatever they want. Just a few of these bonuses include:

Welcome Bonus

This is your welcome to an online casino in the USA. The welcome bonus is usually a match deposit, for example, the casino would match your deposit 100%, up to $1,000. That means you basically double your money before you even make a bet.

Free Spins

Free spins can also be included in the welcome bonus, or they can come on their own. These free spins can be used to sweeten other offers, or they can be used for a new online slot game that the casino is promoting.

No Deposit Bonus

A no deposit bonus is just that: you receive a bonus without making a deposit. It might be free spins, or it might be a small amount of money that you can bet with. But it’s extremely popular with online casino players for obvious reasons.

Reload Bonus

A reload bonus is usually a deposit bonus that can occur on a weekly basis. It isn’t usually as good as the welcome bonus, but receiving a 50% bonus on a deposit is better than 0%.

Loyalty Programs

Loyalty programs used to be just for the high rollers. However, many online casinos in the USA will enter you into the loyalty program as soon as you sign up. The more you play, the more points you receive to move up through a tiered system. As you progress, you can get a dedicated account manager, higher limits for deposits and withdrawals and many more perks.

Online Casino Reviews

online casino usa

Our online casino reviews are written by our team of experienced experts, who sign up, log in and tell you how these sites work from start to finish. We evaluate our casinos based on:

Bonuses and Promotions

Again, we examine how good the welcome bonus is, and whether they offer more bonuses for players.

How can you make deposits? Bitcoin? Credit cards? E-wallets? Wire transfers? We tell you so you don’t have to search for the information.

Variety of Casino Games

We let you know what real money casino games you can find, and what games you won’t find at online casinos in the USA.

Mobile Casinos

We also let you know how good the mobile casinos are. Most sites allow you to play through the browser, but we also tell you if you need to download a casino app.

Safety and Security

Safety and security is paramount when it comes to online casinos in the USA. We make sure that you are only playing and betting at the safest online casinos in the USA, so you only need to think about winning.

Customer Service

In the event you do need help, it’s nice when an online casino has good customer service. We wouldn’t send you to a place with poor customer service. We also want to send you to online casinos in the USA where you can receive customer service around the clock.

How to Choose an Online Casino

What Games Can You Play At Online Casinos?
  • Slots
  • Poker
  • Blackjack
  • Roulette
  • Baccarat
  • Live Dealer Games
  • Bingo
  • Keno
  • Craps
  • Sic Bo

Our online casino reviews will looking into the main aspects of selecting an online casino in the USA. However, you should take note of some other points.

How Popular Is It?

If an online casino is popular, you can usually deduce that they’re doing something good. You can check this out yourself  by heading into poker rooms to see how many seats are left at the tables. You can also do this with blackjack and roulette, among other games. But player traffic is a good indicator of a successful online casino in the USA.

What Software Are They Using?

Software should be discussed in our online casino reviews, but it is very important to how a site runs. Is it easy to navigate? Are the games running smoothly? Are you getting kicked out all the time due to a poor connection? Are they using top-of-the-line software providers for their games? How are these games running as mobile casinos? These are all aspects you need to take a look at.


Can you tell bonuses are important? We cannot stress them enough. Bonuses are the best way to build your online casino bankroll up and just as importantly, keeping it topped up.

Game Variety

Again, this has also been mentioned before, but it is very important. Many online casino players like variety, so they can jump around from blackjack to slots, maybe throw in a little poker and then on to roulette. Some players like one game and they stick with it. But game variety is huge in the eyes of most online casino players.
