Best Slot Sites
The best slot sites are the ones that combine entertainment with the possibility of hitting a big jackpot. It might seem like you could just sign up for an account at the first search listing in Bing or Google and be off to the races, but that’s a big mistake.
Your best bet is to find a guide to the top slot sites that you can trust. This will help you avoid scams. We recommend the following websites:
You can play free online slots right here on our site. SlotoZilla has more than 3,000 of the best free slot games available for players. Are the payout percentages different between real money and free play slots? No, payout percentages are identical whether you place real money bets or play free online slots machines. The best gambling sites in the USA list hundreds of online casino games from different software providers. The various games on the menu are table games, video poker, progressives, and specialty games. There’s absolutely no shortage of slot machines to play at our best online casinos in the USA.
| Rank | Gambling Site | Deposit Bonus | Get Started | |
| #1 | 100% Up To €250 | Visit Site | ||
| #2 | Europa Casino | 200% Up To €500 | Visit Site | |
| #3 | 100% Up To €400 | Visit Site | ||
| #4 | Spinia | 100% Up To €250 | Visit Site | |
| #5 | 100% Up To €400 | Visit Site | ||
We have a more ambitious goal for this guide of the best slot machine sites
than to just offer you a list of recommendations, though. In fact, you should
expect more than that from any guide.
You’ll find the justifications and criteria for our rankings on the rest of
this page. We didn’t just put together a random list of the “top” slot machine
websites. We considered several factors, and you should understand all these
when deciding where to play.
What Makes a Slot Site the Best
When we say that we’re going to provide information about what makes a slot
site the best, we’re talking about the factors that we consider when ranking
slots sites. It’s about more than having the best games with the best graphics
(although, that’s a factor).
We want to account for other factors which are just as important to a slot
machine gambler but aren’t as readily apparent. Below, we’ve listed the factors
that make a slot site the best.
High Payouts
Probably the most important consideration for evaluating a casino for this
list of best slot sites online is payback percentage (or return to player). Some
players worry about this too much, but others don’t even consider it. We’ve
tried to list the online casinos with the best slots in order of payback
percentage.
What does that mean?
It’s just the statistical average payout divided by the amount of money
you’ve wagered on the machine. A slots game with a payback percentage of 96%
will win 4% of your aggregate wagers in the long run, while a slots game with a
payback percentage of 95% will win 6% of your aggregate wagers in the long run.
When you’re looking at an average of 600 spins per hour, you’re talking about
putting at least $150 into action per hour, so the difference between 4% and 6%
adds up.
Keep in mind, too, that the payback percentages advertised for various online
slot sites are estimates based on all their games over time.
Some slots games at these online casinos might have a payback percentage of 95%, while others might
have a payback percentage of 75%.
If you’re intrigued by this concept, it’s easy to enough to track your wagers
and how much money you’ve lost. With enough spins in your database, you can
start to estimate the payback percentages for the games yourself. Just keep in
mind that in the short run, your actual payback will be at the whim of
short-term variance.
Of course, we don’t have access to the algorithms behind the games. We
base our rankings of payback percentages on anecdotal evidence and our own play
at these sites.
The best payout percentage we’ve seen for a slot machine game is the
Cosmic Quest slot game at Café Casino. If that’s your most important criterion,
you should sign up there and play Cosmic Quest for yourself.
Variety of Games
The casino sites with the best slots also usually have the best variety of games to choose from.
If all the games are similar in presentation, you’ll get bored fast. This means
different games with different themes and payback structures make for the best
player experience.
Sometimes, you might be in the mood for a game with three reels and a single
payline and traditional symbols like cherries, bars, and plums. Other times you
might prefer a five-reel game with 25 paylines and multiple bonus features. You
might even be looking for a game with a progressive jackpot.
Each of these types of games has its pros and cons. A three-reel, single
payline game usually has a higher payback percentage than the other types of
games available, but the top jackpot is usually limited to about 1000 coins. The
games with more reels and more paylines are more exciting and have bigger
prizes, but over enough time, you tend to lose more money.
The games with the lowest payback percentage are the progressive slots, but
players who love those games don’t care about the statistical payback
percentage. They want a shot at a jackpot that could change the quality of their
lives.
We’ve chosen this list of slot sites because they offer each of these experiences.
If you’re looking for the site with the most slots games, try Bovada
Casino. They offer over 500 different slot machine games from multiple software
providers. You can also play poker with other real players and bet on sports
there if you need a break from the one-armed bandits.
Mobile Compatibility
At one time, everyone interested in the sites with the best slots focused
entirely on playing these games from their desktop computer. Eventually, laptop
computers got strong enough to use, too. Mobile compatibility wasn’t an issue
until recently.
But now that it’s an issue, it’s essential for most slots players. After all,
how many people do you know that strictly use a flip phone and only access the
internet from their laptop or desktop computer?
The level of graphics and sound effects provided by these games as part of a
mobile user experience are a major criterion we used to develop this list of
recommendations. We understand that most of our players are interested in
playing mobile slots.
Ignition Casino offers the best mobile compatible slots. We recommend
trying Ignition if you’re planning to play from your mobile device most of the
time.
Bonus Offers
It’s impossible to create a list of the best online slot sites without
considering who has the best bonus offers. If you’re not familiar with how an
online slots casino bonus offer works, it’s simple:
To incentivize signups, online casinos offer free money when you make your
first account. They add this money to your account as a percentage of your first
deposit. You then must make a minimum number of wagers before cashing out your
winnings.
The biggest signup bonus you’ll find is at Sloto Cash. They offer a
200% signup bonus of up to $7777 on your first five deposits. To take full
advantage of this bonus, you only need to deposit $3889 over five deposits. When
you do, you’ll get the $7777 bonus added to your account, which means you’ll
have a total bankroll to play with of $11,667.
You can chase jackpots for a long time with a bankroll like that.
And if that’s not enough, Sloto Cash also offers new players 300 free spins.
Café Casino offers a great bonus offer, too. Deposit $1000, and
you’ll get a 500% bonus of $5000 added to your account. This means you’ll have a
total bankroll of $6000 to play with.
Of course, you can’t cash that money out unless and until you meet the
wagering requirements. One of the requirements for being listed here is that the
casino in question has reasonable wagering requirements.
With the bonus offer at Sloto Cash, you’re required to wager 60x your deposit
plus bonus. With the bonus offer at Café Casino, you’re required to wager 35x
your deposit plus bonus.
If you have the bankroll to afford it, we recommend taking advantage of both
offers. Get as much free money to play with as you can.
Tournament Availability
It’s hard to list a company on a list of top online slots sites if it doesn’t
offer slots tournaments. And if you’re not familiar with how online slots
tournaments work, you’re missing out.
The site has a starting time for the tournament. You usually pay an entry
fee, although some slots tournaments are free.
Everyone who pays the entry fee gets the same number of credits to play with.
You use those credits to spin the reels. Your goal is to have the largest number
of credits at the end of the tourney.
It’s important to remember that these credits are only useful in the context
of the tournament. They’re like Monopoly money. They’re just used to keep score.
The best way to win one of these tournaments is to make as many spins as
possible so that you can book as many wins as possible. Of course, there’s no
more skill involved in a slot machine tournament than there is in playing online
slots for regular money.
Online slots tournaments are generally special events or promotions offered
periodically by the top casino sites. Sometimes they even offer free entries into
freeroll slots tournaments where you can win real money. Your entry is comped
based on the amount of play you’ve brought the site over time.
The top slot sites for online tournaments are listed above including
Sloto Cash and Slots.lv. Of those Sloto Cash offers more tournaments more often
and with lower entry fees.
Software
The top online slots sites use multiple reliable software providers. A
decade ago, most of these kinds of sites only offered games from a single
software provider, but now, most offer multiple games through multiple
platforms. This provides players with a bigger variety of games to choose from.
Our favorite site based on software is Bovada, although Slots.lv is a close
second. Both sites offer slot machine games through RTG, Rival, and Spinomenal
software packages. RTG provides both sites with slot machine games like The
Three Stooges and Cleopatra’s Gold.
We’ve already talked about what big fans we are of Cosmic Quest
slots, which is one of the top-tier games offered by Rival licensees. Midway
Madness is another fun game from Rival that’s available at these casinos.
Our favorite games from Spinomenal include Demi Gods II and
Lemur Does Vegas, both of which offer unique experiences unavailable in
traditional land-based casinos.
But any of the sites on our top online slots casinos list offer multiple
games from multiple high-quality software providers. You won’t find a loser in
the bunch.
Country Considerations
The best slot sites online offer service to the widest range of countries. It’s hard
for us to list a slots site here if they don’t accept real money players from
the United States, for example.
We won’t get into details of the legal situations in various countries. In
fact, these recommended sites aren’t available to all players in all countries
(or even jurisdictions within countries).
You should always check your local laws before playing on these online slot sites for
real money. We’re convinced that in most jurisdictions, your legal risk is
negligible, but that doesn’t mean its nonexistent. We disclaim any liability
based on decisions you’ve made. We assume you’re an adult of decision-making age
who has done their due diligence before deciding where to play.
Suffice it to say that most of the top slot sites listed here operate from
the assumption that the gambling is taking place in THEIR jurisdiction not
yours. Since they’re licensed and regulated there, no laws are being broken.
Other properties operate from different assumptions, but if they have a large
number of countries that they disallow play from, we disqualify them from our
list.
All of the properties on our list of best slot sites accept players from most
countries – even the United States, which is the country that seems to get singled
out for discrimination among online casinos more than anyone else.
Customer Service Considerations
Anyone doing research into which top slot sites deserve to be ranked “the
best” would be negligent if they didn’t spend time researching customer service
complaints on the various player forums on the internet. Not only should
customer service operate during reasonable hours (preferably 24/7), but they
should also offer multiple avenues for contacting them.
Some of our visitors prefer to talk on the phone, while others prefer to send
an email and get a response via email in a timely manner. Some of our visitors
probably prefer live chat support.
We’ve tried to be sensitive to these preferences when putting together this
list. The online casinos with the best slots on this list have minimal
legitimate complaints made against them in the most popular player forums on the
internet.
Licensing and Regulation
One of the first things we look for when evaluating for the best slot site is
where they’re licensed and regulated. Most online casinos are licensed and
regulated somewhere, but some jurisdictions provide more oversight than others.
Obviously, the jurisdictions which provide more oversight provide a safer
experience than the jurisdictions providing less oversight.
And naturally, we eliminate any site from consideration from our list if it
doesn’t prominently display information about where it’s licensed and regulated.
Here’s a list of jurisdictions which commonly license and regulate slots
sites online, we’ve ranked them from best to worst, in terms of oversight and saftey
- Kahnawake
- Antigua and Barbuda
- Curacao N.V.
- First Cagayan Philippines
- Costa Rica
Most of the sites that made our list are licensed in Kahnawake, but at least
one is licensed in Curacao. Some even more restrictive jurisdictions often
restrict real money players from the United States, so we’ve leaned toward
listing the sites with licenses from jurisdictions that allow play from most (or
all) foreign countries.
Online Casinos With the Best Slots
Above are the five online casinos with the best slots.
We’ve included some observations about what each of these sites bring to the
table and what qualifies them for this list below.
Ignition Casino
Ignition Casino caters only to slots players from the United States and
Australia, but their selection of games is unrivaled. They offer slot machine
games powered by their proprietary software, as well as offering games from
Rival, RTG, Revolver Gaming, and Spinomenal software.
If you’re one of those slot machine players who also enjoy poker, you can
play real poker with other players there. Their customer service is second to
none, and they have a wide variety of deposit and payout options. The gambling
age at Ignition Casino is 18+, making it friendlier for younger gamblers than
some of the other top online slot sites.
Bovada Casino
Most people associate the Bovada brand with sports betting, but they offer
one of the most robust casino platforms on the web. Bovada serves a broader
worldwide audience than Ignition Casino, having customer support and websites in
the following languages:
- Chinese
- English
- Portuguese
- Spanish
They also use proprietary software for some of their slots games, as well as
offering the most popular slots games from RTG, Rival, and Spinomenal. Bovada is
also completely mobile-friendly.
Café Casino
Café Casino is known for being friendly and welcoming to players from the
United States. They offer one of the best signup bonuses for slot machine
players, and they also feature games from a variety of software providers,
including Betsoft, RTG, Revolver, and Rival.
Café Casino, like Ignition, operates primarily in the United States. If
you’re a player using Bitcoin to gamble with, this is one of your best options.
Sloto Cash
Sloto Cash Casino offers a wide variety of mobile-friendly slots games using
both RTG and BiG software. Slot sites like Sloto cash are avaliable in English and serve mostly a
United States-based market, although Sloto Cash does not accept real money
players from states with restrictive gambling laws like Kentucky, Louisiana,
Maryland, Missouri, New Jersey, New York, and Washington.
If you’re looking for the biggest signup bonus, you won’t find a better offer
than the $7777 in free money at Sloto Cash.
Slots.lv
Slots.lv specializes in slots and related games like bingo games and lottery
games, especially scratch and win games. Most of the games are powered by RTG
and Rival, but Slots.lv also has some of its own proprietary slot machine games
on offer.
Slots.lv is mobile-friendly and caters to a United States audience. Slots.lv
also accepts players from China.
Conclusion
That’s our detailed look at the best slot sites online. Whether your goal is
to while away some time or win a big jackpot, the top slot sites on this list
should fill your needs with minimum customer service hassle and a maximum of
payouts.
Don’t sign up for just any casino site. Insist on only playing at the top
slot sites online, like the ones listed at the top of the page. You work hard for your
money, and you shouldn’t gamble with it at shady operations or casino sites with
a minimal variety of games.

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.
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.

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!
