How We Recommend Casinos With the Best Slots

We live in a day and age where anyone can start a website and leave reviews and recommendations. This means that people have to be all the more careful about who they trust.

That’s where The Sports Geek comes in. We don’t want you to think for one second we don’t care about our readers. We take the time to carefully choose which sites we are going to put in our recommendations. We have an extensive review process that we go through with every real money online casino and slot machine app. For your peace of mind, we’ll give you a glimpse into that process now.

If you want to have more detail, you can read how we conduct our reviews in full here.

Sites

We Always Check User Reviews

Just like if you were buying anything else online, you always want to look at user reviews. Sometimes an individual will have a bad personal experience with a real money slots app or gambling site and as a result, leave an overly critical review.

On the flip side, people will leave positive reviews because they are getting paid to do so. For this reason reviews of online slots casions don’t tell the full story. It’s not easy, but we do our best to sift through many reviews and determine which ones are actually legitimate based on the wording, user reputation, and our own personal experiences with using the casino sites.

Reddit is a great platform to check for reviews as they have moderators in the forum that usually eliminate spam postings.

We Test Payouts

One thing that we feel genuinely sets us apart from the rest of the pack of reviewers is our testing of the banking options at any real money slots casino. Choosing a USA casino site is no small task, and ensuring safe deposits and withdrawals is our first priority when playing online slot games for money.

We go as far as to make a few separate accounts and try making deposits and withdrawals. We make sure that each of our users can seamlessly make deposits, play some games, and get money withdrawn in a timely fashion.

If we experience any hiccups, we go straight to customer service to see if we can get it straightened out. If we get the workaround from them, we know we’re in the midst of a shady operation.

We Use Every Form of Contact the Real Money US Casino Offers

You’ll often find a few different types of contact, such as email or a phone number at the casino you choose. Sometimes, you might even find live chat. There are a few other options, but no matter how many there are, we test them all. It doesn’t matter how many online slots casinos we visit, we check every single option, every single time.

We are looking to see how quickly they respond and if they get back to us in the timeframe they claim. For example, if an online casino states that they will respond to any questions within 24 hours, then we expect them to uphold that standard.

Another thing we examine is how they talk to us. We don’t want them to know we are reviewers, so we make sure to come off like the average joe looking for help.

We want to know whether they address issues and concerns in a helpful, quick, and responsive fashion.

Most Popular US Slots

Not settled on a site quite yet? Maybe you just want to know what games are available for US players? Never fear, because yet again, we got you covered!

Let’s go over a few of the most popular US real money slot machines that you can currently find.

Megabucks

Megabucks is a fan favorite to many US slot players. This game has a spectacular progressive jackpot that just keeps reeling players back time and time again. Powered by IGT software, it’s no surprise this game functions as flawlessly as it does. With great sound effects to accompany everything else, there’s no reason to not try out Megabucks today!

Buffalo

As a team that really loves real money online slots, this one is one of our favorites. The original Buffalo slot machine was released by Australian casino gaming manufacturer Aristocrat Leisure in 2008. In the modern version, there is arguably no better sound when playing online slots for real money than hearing that “Buffalo!” yell out at you. If you’ve never heard that sound, you need to stop what you’re doing and go try it right now!

Mega Moolah

Do you need a few extra million dollars? Of course, you do! Mega Moolah holds the record for the biggest online slot jackpot win of $16.4 million. Mega Moolah is a go-to for US players with its massive payouts and unique gameplay. No need to hunt any further for a great online slot game, Mega Moolah is for everyone!

Reasons to Play Online Slot Games for Money

Do you need any more convincing as to why you should play some real money slot machines? Here are a few of the pros you can look forward to.

Easy to Get Started

We’ll talk about this in a little more detail later, but it’s worth noting now. Real money slots are super simple to get started with. If you are in the US and looking for a way to wager some money with ease, online slots are the way to go!

Lots of Variety

No matter what casino you choose, you will be greeted with a library that has the largest number of game variations available. Sure, you can find plenty of blackjack and roulette variations, but the slot libraries will have hundreds of real money casino games to choose from!

Potential to Win Huge Jackpots!

If you are a sports bettor, you know the drill with placing bets. One of the downsides to sports betting is your winnings are capped based on how much you bet. With real money online slots in the USA, you can max bet a certain amount for the chance to win possibly millions of dollars! All jackpots are different, but depending on the game, the chances are there!

Playing Slots vs. Sports Betting Why You Can Enjoy Both

Real money online slots are definitely not in the same realm as sports betting. When you get right down to it, the only real similarity is that you are wagering money.

For avid sports bettors, we take an extraordinary amount of time to research our sport of choice and dive into a mass amount of spreadsheets and data tracking. However, when you sign onto a slots online casino to play some games, you can turn your brain off for a little while.

Admittedly, that might not sound like something overly enthralling for some, but it can be great for sports bettors in the long run. For sports bettors that are working day in and day out on their trade, it’s nice to have a scapegoat to help relieve some stress and just not think about stats and numbers for a while!

And you should have no trouble finding a real money slot game that you can enjoy! You can always find real money online casinos with mass quantities of casino games and different kinds of slots. Don’t let people tell you that you can’t enjoy betting on sports and play real money slots in the US; it is entirely possible, and our team is proof of that!

Closing Thoughts on Real Money Online Slot Games

All in all, real money US online slots are a great way to pass the time and win some cash! We hope that after reading this, you can better trust our casino recommendations. And also that you feel like you know more about real money online slots and are now better equipped to play them.

If you have any other questions or concerns, you can refer to our FAQ section below. If we don’t answer any question you might have, you can contact us, and we will try and answer it as quickly as possible.

What Makes One Slot Machine Website Better (or Worse) than Another

With all of the choices that players have today for online slots casinos, it can be easy to just pick the first one that pops up in a search. But a question that needs to be asked before trusting this company with your money is: what makes this the best online slots casino for me?

The answer to this question is a complicated one because it can be subjective. A person may like the way a certain site looks. Another may like a bonus offer that the site offers. Still another may like the types of slots offered.

In any case, there could be dozens of reasons why a person likes a certain casino.

But are these personal preferences the only thing that should be considered?

The answer in most cases is no. Personal preferences should only play a small fraction of the reason chooses slots sites online.

When choosing the online slots sites that you wish to play, you should consider a number of factors that relate to the money you’re spending, the information that you provide to the website, and your overall enjoyment.

Online Casino Reputation

Reputation means everything.

It’s not just true in finding the best online slot machine sites but in any business.

Many people will look up reviews of businesses before patronizing them. This is quite common when someone is thinking of trying a restaurant they’ve never eaten at previously. If you were to research a restaurant on a review website such as Yelp and saw that the customers gave poor reviews and said such things as they had poor service and the food made them ill, would you still want to try the restaurant? In all likelihood, you wouldn’t.

The same is true for an online casino. While there’s no Yelp to help casinos with the best slots, sites like onlinecasino.info and casino.org provide reviews of many online slots sites to help you understand their reputation as well as other factors.

The sites that have the best reputations are the ones that have been around for many years and have subjected themselves to some type of local jurisdictions and have been issued licenses by a gaming authority. Other factors may play a role in the reputation of an online slot machine casino as well.

Online Gaming License

Among the traits that make a casino or slots site among the best and safest is where and how they’re licensed. A site that’s totally disreputable won’t even bother with licensing and place their website services in a jurisdiction that doesn’t require any licensing.

Most reputable sites will be licensed by a governmental agency. The most common and reputable authorities include:

  • Alderney Gambling Control Commission https://www.gamblingcontrol.org
  • Gibraltar Gambling Commissioner https://www.gibraltar.gov.gi/finance-gaming-and-regulations/remote-gambling
  • Isle of Man Gambling Supervision Commission https://www.gov.im/categories/business-and-industries/gambling-and-e-gaming/
  • Kahnawake Gaming Commission https://www.gamingcommission.ca/
  • Nevada Gaming Commission https://gaming.nv.gov/
  • New Jersey Casino Control Commission https://www.nj.gov/casinos/
  • UK Gambling Commission gamblingcommission.gov.uk/

All of these licensing authorities have among some of the highest standards when it comes to the licensing of online casinos and slot machine websites. These commissions regularly assess that these sites are following rules and regulations set forth by the commissions. These commissions also have set up ways that consumers can report problems with the casinos licensed under them and have these issues investigated and addressed in a prompt manner.

Free Online Gambling Slots

Not all online gaming licenses are equal, however. Licenses issued under that Government of Curaçao are no more than a business license that anyone can obtain. Curaçao has no infrastructure to handle complaints or investigate casinos that are acting in bad faith. This isn’t to say that casinos licensed out of Curaçao are unscrupulous, simply that the licensing authority doesn’t have the same safeguards as others that have been mentioned.

Customer Support Availability

The best online slots casinos have multiple ways in which a customer can get help when needed. This is true for any business.

For many players, this boils down to personal preferences. Some players like the ability to call someone and talk on the phone. Some are fine with the ability to simply email customer support. Others may like an interactive chat for help.

When seeking out an online slots site to play at, you need to look at when they offer for customer service. Most sites will show their options on the main page of the site. Factors you should consider are:

  • The hours that customer service is available
  • The methods in which you can contact customer service
  • The country the casino is based out of (for time zone and language purposes)

One of the big trends in customer service for online casinos in the last few years (as well as other businesses) is the use of bots or automated chat response systems. While these are designed to provide users with the quickest responses, they’re not always the best.

As a rule of thumb, before depositing any money at an online slots casino, try out their customer service. Ask questions of them that you may have. See if the options for customer service work best for you.

Casino Software Reputation

The casino software industry has been steadily growing for the last 2 decades. A majority of online casinos buy software packages from an online casino software supplier. These suppliers offer customizations to the casinos based on their needs. This is why you can go to an online casino and possibly see a slot machine that’s featured at another online casino. This is similar to walking into 2 different grocery stores and seeing both sell Pepsi.

For the most part, an online slots casino will only feature one software provider’s games. Among the most popular and most respected software companies are:

  • Real Time Gaming (RTG)
  • Playtech
  • Microgaming
  • Aristocrat
  • Interactive Gaming Technology (IGT)
  • NETent
  • Novomatic
  • Next Gen Gaming (NYX)
  • Betsoft

These companies offer not only safe software but have a reputation for keeping up with technology. For example, many games from a decade ago used a technology called “flash” and many casinos touted this technology by advertising “flash” games. As time passed, the major players in the internet browser industry realized that flash had limitations and even some security concerns, so they moved away from supporting it. In the next few years, it may not be supported at all. This was a major concern for many online casinos and software companies took note by upgrading the technology that conformed to the new browser specifications and provided a smooth transition to the new experience for customers.

Reputable software companies are concerned with the player experience. They look for new technologies (such as games involving virtual reality, mobile gaming, and 4k and 8k video displays) and they look for the most secure ways for a player to enjoy the games so that they don’t have to worry when providing a casino their personal information.

Number and Variety of Games Offered

Some online slot casinos offer only a handful of games. And this can be attractive to some players. But the online casinos with the best slots offer a wide variety of themes and types of games.

Some of the types of online slots that the top slots sites offer include:

  • 3 reel slots
  • 5 reel slots
  • 6 reel slots
  • 7 reel slots
  • Progressive slots
  • Mobile slots
  • Multi-pay line slots
  • 3D slots
  • i-slots (interactive slots)

Best Online Gambling Sites Slots

While these slots may not be available at every online slot casino, most will have a majority of these types. Some may have some not listed for you to try.

To get an idea of the different types of slots that can be played online, a number of people have posted videos on sites like YouTube and Twitch to give a unique perspective of how the games work. One such YouTube channel that streams live online slots play is JimboCasino. The videos usually last about 30 minutes and give the player an idea of how a casino bonus will play out in an online slots casino.

Casino Bonuses

When playing at the best slot websites, players should take into consideration the bonuses that the casino offers.

The most common bonus offered is a welcome bonus. In this type of bonus, you’re either matched dollar-for-dollar (or whichever currency you use) or you’re matched by a percentage of the money you deposit when opening an account up to a certain amount.

For example, a website like Café Casino (cafecasino.lv) offers a 500% welcome bonus up to $5,000. That means that for your $5000 investment, you’ll receive $25,000 to play with.

But casinos offer other bonuses too. For example, some offer reload bonuses that work similarly to the welcome deposit. These deposits are matched either dollar-for-dollar, by a percentage, or in some cases a flat amount (a minimum deposit is usually required).

Other types of bonuses that slots machine casinos offer include referral bonuses, bonuses for playing on certain days, VIP bonuses, high-roller bonuses, and tournament bonuses.

Bonus Terms and Conditions

While bonuses are great and can provide a lot of extra money to play with, they always come with strings attached. This is for their protection. In the offer from Café Casino, it wouldn’t make sense for them to give a player $25,000 for only depositing $5,000 if the player could just take the money and run.

By accepting a bonus, you’re accepting the terms and conditions that accompany that bonus. In the case of Café Casino, by accepting the bonus, you agree to the following:

“The deposit plus bonus amount is subject to a 35X playthrough requirement as well as a max cash out of 10x the value of the deposit. Any winning above the 10x deposit amount, based on the bonus code will be forfeited upon cash out.

Some games contribute towards playthrough requirements; however certain games may have a greater contribution than others. For more information please view our wagering contribution chart.”

So in order to take advantage of the deposit bonus, a player must play the slots 35 times. Also, the player agrees to forfeit any winnings that are higher than 10 times the deposit. So in the case of a $5,000 deposit, the maximum that a player can withdraw is $50,000, no matter how much they win.

So it’s important to be aware of the terms and conditions of any bonuses that are accepted. If a player doesn’t want to accept the bonus terms, they’re welcome to deposit their money and decline any bonuses which will eliminate the bonus restrictions, although the casino may have limits on how little or how much can be withdrawn at one time.

Player Loyalty Programs

Player loyalty programs for online casinos are similar to comp points in a land-based casino. A player usually needs to sign up for the rewards program and once signed up, the player receives points for every dollar spent. These points accumulate into prizes and cash that the player can use to put towards betting. In most cases, there’s no fee to join a loyalty program.

Overall Average Payouts

The payback percentage for a slot machine game is determined by 2 factors:

  1. The prize amounts
  2. The probability of winning those prizes

Most slot machine games have a payback percentage in the 75% or higher range, which means that–on average–you’ll win back 75 cents every time you bet $1.

Your goal when choosing an online casino is to find a site with higher-than-average payback percentages.

Free Gambling Slots

But as luck would have it, I’ve done the hard work for you–the 6 slots sites listed here all have payout percentages of 95% or more on average.

Online Slot Tournaments

No casino can claim to be the best online slots sites without adding an element of fun to the gameplay. That’s why many conduct tournaments for players.

These tournaments allow players to pay a flat fee to compete against other players. Instead of winning money with each spin, the players accumulate points. Tournaments provide an opportunity for players to play slots without losing money on each spin. They also allow the competitors to win small prizes such as casino swag during the tournament. The real payoff, however, comes in the form of the prize pool. The prize pool is based on the number of players that have entered the tournament. The casino usually pays out a percentage of the entry fees collected to the top point accumulators.
