Learn more about these amazing USA online slots casinos below.
What is CasinoSmash?
CasinoSmash is an independent website. We are not related to any of the operators you see listed on our site. Our mission is to help players find the best slot sites and discover all the best online slots.
We run independent tests of all the platforms and games we describe and we may earn a commission when our players register and begin to play on any of the sites we recommend.
We are in the business of reviewing casino sites since 2013 and we are considered to be one of the most authoritative and trustworthy casino guides in this field.
How Do We Pick the Best Slot Sites
A website with reviews and suggestions may be created by anybody, and community-led sites like Quora and Reddit are full of self-proclaimed experts ready to give their advice on just about anything.
As a result, players must be much more cautious about putting their confidence in what other people have to say about the best websites to play slots online.
That's when CasinoSmash steps in to save the day. Since 2013, we take time to thoroughly choose the websites that will be included in our suggestions.
Part of one of the largest groups in online gaming that includes award-winning websites like OddsChecker and WhoScored, we go through a rigorous evaluation process that takes many hours for each and every real money online casino and slot machine app that we assess.
In the part that follows, we are going to share with you some of the key factors we consider when we analyse slot sites.
The Ranking Methodology
You should always read user reviews when playing slots online, just as you would if you were purchasing anything else online. A user may have a negative personal experience with a real money slots app or online slot site and, as a consequence, submit an unduly critical review.
The opposite is also true: players who are paid to submit favourable evaluations will do so because they are being compensated. So reviews of online slots sites don't reveal the whole picture.
There are a lot of reviews to wade through, but we try our best to sort through them and identify which ones are credible based on the language, user reputation, and the result of our special tests of all the casino sites we evaluate.
When it comes to deciding whether or not gambling sites deserve a place in our list of the best options to play real money slot games online, we apply a ranking methodology that is based on six pillars:
- Licensing Information
- Game Providers
- Free Slots
- Online Slots Payout
- Player Support
- Free Gambling Addiction Resources
1. Licensing Information
Our list of the best online slots sites includes only casino operators that are legally allowed to offer real money games. Before we get onto the analysis of games, platforms, and bonus offers, we make sure the sites we suggest have the correct licenses to let users play real money slots online.
2. Game Providers
There are so many online slot games available online that no one can really understand the exact size of the industry. Some game creators have been launching new games for the most part of the past 20 years - and we have reasons to believe they too have lost count of how many slots they have in total.
Some of the real money slot sites on this page list thousands of options. However, like in everything in life, quantity and quality are not always the same thing.
To make sure you can enjoy playing real money slots by accessing all the best titles, we assess all the developers offered by each gambling site and use this information for our ranking algorithm. Of course, having games from giant like NetEnt, Microgaming, and Playtech is always a good thing.
3. Free Slots
Giving players the opportunity to win real money is great and finding the best gambling sites for is what this page is all about - but we believe free online slots are equally important. That's why we make sure all the casino sites we review offer ways to play free slots.
We will let you know if this happens with free spins or with demos of the real money games - but be sure of this: for an online casino to make it to this list, they need to offer free slots to our players.
While only a minority of players will use their bankroll to chase the biggest progressive jackpots on jackpot slots, we believe fairness and transparency are basic requirements that every real money slot site must guarantee to their users.
If you play slots for real money, you need to know the site of your choice will pay your winnings in a timely manner and without forcing you to go through any hurdles.
One thing that we think truly sets us apart from the rest of the sites about online slot machines and casino games in general is how we test the banking options at any real money slots casino.
When we play online slot games for money, the first thing we want to do is make sure that our deposits and withdrawals are safe.
We even set up a few separate accounts and try depositing and withdrawing money to see if that works for us. Users should be able to easily deposit money, play some games, and get their money back quickly.
We also test the deposit bonuses to make sure we can use them to start playing online slots games as promised. If we get free spins and we win real money, we double (sometimes even triple) check the wagering requirements to make sure all slot bonuses work as advertised.
5. Player Support
When you join one of the best online casinos, you'll usually discover a few various ways to contact their support service. The most common ways to seek assistance are via email or phone, even if more and more online casinos have started to include the option to talk with a support representative right away via live chat.
On occasion, there can be a few additional alternatives. We make sure to test them all regardless of how many there are and how much time it takes us to complete our 'mission'. We check every single option available at every online slot casino, every single time, no matter how many online casinos we visit.
During this test, we have a script that includes a number of defined goals. Before we suggest you any sites to play popular online casino games, we want to see how quickly and how long it takes them to get back to us. The way we think about it is that if an online casino says that they will answer any questions about casino games, payments, bonuses and promotions within 24 hours, we expect them to live up to that promise.
Another aspect we look at is how the online casinos communicate with us. Rather than coming across as reviewers, we pretend to be a regular person seeking assistance.
6. Responsible Gambling Tools
Playing slots online should be fun and exciting - that's why we reward the online casinos that go the extra mile in providing tools to reduce the risk of problem gambling issues. When you play online slots (and all sorts of casino games), you need to remember that you should not chase real money wins and you should not see online gambling as a way to win money online.
The odds in video slots favor the house so, in the longer term, the online casinos have an unbeatable advantage over the players even when you pick the best online slots available.
Whether you play progressive jackpot slots or classic slot machines, you should always do so by setting some clear limits to yourself. When an online slot site makes this easier by offering their users some tools that make playing slots safer, we give them extra points.
Best Real Money Slots for US Players
In the list below, we bring you the top online real money slots games available to play this month. In addition to the RTP % - which is one of the top elements to consider when you try to pick a winning slot machine -, we also included the online slot game provider, the stakes, and the jackpots you may dream of while playing for real money.
Slot Machine Software
Popular Slots and New Slots
Every month, the best game providers race to bring players new slot games to try and explore. A quick look at the titles listed on the top slots sites today shows you how far this innovation went and how different the newest slots are when compared to the classics that made Las Vegas and Atlantic City famous.
From NetEnt's attempt to bring the adventure of Gonzalo Pizzarro to the world of virtual reality with Gonzo's Quest VR to the innovative gameplay introduced by the Street Fighter II slot, the games we play in this decade are so evolved that comparing them to old slot machines like Liberty Bells and Mega Bucks would be simply unfair.
Video slots are the casino games that most benefitted from the technology advancements that happened in the last 20 years, giving players the opportunity to enjoy games that get more complex and entertaining every month.
The downside of this race to impress players is that there are too many slots out there - and as the paradox of choice tells us, having 1,000s slot machines to choose from isn't always good for those who want to try the best games.
Our list of the most popular slots helps you find all the games to try based on industry ratings and what other players are playing.
Using a proprietary algorithm that combines casino and industry data with feedback coming from real players, we are able to suggest all the best games to play every month - giving you a good mix of old and new slots to try.
On top of that, we match the games with the casinos that are available in your location, so we can also suggest what are the highest-rated slots site when you can play each game.

Online Slots for Real Money v Free Slot Machines
Are you still undecided about whether or not to play slot machines for real money? Here are some of the things you can expect when you join online slot casinos.
Easy to Learn How to Play Real Money Slot Games
We talk about this on a specific page dedicated to how to play slots, but now is a good time to point out this important element. Getting started with online casino slots is super easy - to the point video slots are considered to be the easiest game to master compared to all other games you can win real money.
If you live in the United States and are seeking a convenient to get started with online gambling, slots are the way to go - especially if you are not too familiar with other casino games like table games and video poker.
Keep in mind that all slot games play the same, so you don't need to spend your cash if all you want is to learn how to play online slots. If that's the case, the free slots you find on all the best online casinos will work just fine for you.
Lots of Themes and Game Types
Every real money slots site features an impressive number of slot games to play. From classic slots like Book of Ra, Starburst, and Buffalo Blitz, to modern slot games like John Hunter and the Quest for Bermuda Riches or games with mind-blowing progressive jackpots like Mega Moolah, you'll have always a lot of slot games to try.
Here on CasinoSmash we try to help you find the best slots for real money with lists that feature the best slot games for each category. If you are looking for a new slot game to try, have a look at these collections of slot games:
- Best games like Scatter Slots
- High RTP slots
- NetEnt slots
- IGT slots
- WMS slots
- Egyptian-themed slots
- Asian slots
- iPad slots
Progressive Slots and Jackpots
Progressive slots are one of the most exciting sides of online gambling. These games come with massive progressive jackpots that can distribute wins for tens of millions.
Depending on the online slots site of your choice, you may access numerous slot game options to chase the biggest jackpots in your state. US casinos like BetMGM and DraftKings specialize in this slot game type to the point they dedicate entire sections to progressive games.
Keep in mind that progressive games can be very expensive and extremely hard to beat. Regardless of the slots site you choose, the only way to compete for the top prizes on a progressive online slots game is to bet the maximum every time you spin the reels. That, in conjunction with a below-average Return to Player % are what make these the hardest games to crack on the casino floor.
Free Spins v Demo games
If you see a site presenting a new game as "the best online slot," make sure you can try it for free with free spins, a welcome bonus, or a demo version.
Since the free and paid versions of every slot game play the same, welcome bonuses that include free spins are your best option to try out a new title risk-free.
Here on CasinoSmash we review all the welcome bonuses you receive when registering on one of the online slots casino sites on our page - giving you full visibility of their free spins and other no deposit bonus offers.
Using bonuses and promotions is not your only option to ensure online gambling stays free and fun for you. If you are not interested in claiming the welcome bonus a casino offers (or you already used all your free spins) you can play free demo games.
The only difference between these ones and the real money ones is that you can't win cash prizes. Everything else is exactly the same.
How Do Online Slots Work?
Online slots are all about luck. Return-to-player rates vary amongst slot games, so look for one with a high RTP rate when selecting one. Determine which symbols to look for by studying the game's paytable. The paytable also indicates if the game has multiplier, wild, scatter, or bonus symbols. If you see a bonus symbol, you may expect to be sent to a bonus round in the game, which might result in cash awards or free spins.
Decide on your wager size and paylines. Before you start spinning, make a spending plan; establish how much money you can afford to spend (or lose) and adhere to it. If you're hoping to win, play slots with lesser jackpots rather than ones with larger ones.
About Casino Bonuses to Play Slots Online
One of the best things about playing online slots is that casinos give you free money and free spins to play. There are many different sorts of bonuses available, so you need to do your research before you claim a welcome bonus. Nearly all the slot sites on this page try to get people to come to their site by giving them big bonuses when they sign up.
Some sites offer free spins as deposit or no deposit bonus offers. These are regular bonuses players can use to try a limited number of real money spins for free.
Free spins bonuses can be triggered also when a player triggers a bonus round in a game. In this case, the free spins enable the player to spin for free an additional number of times.
The best thing to do, when you shop for a new welcome bonus on slots, is to look for huge sign-up bonuses that come with the lowest possible wagering restrictions. This combination increases the amount of real money available to a player.
For your convenience, we collected all the top offers in this simple list of the best casino bonuses. Before taking any casino offer, make sure you completely grasp the terms and restrictions.
Check to see whether there's a time restriction on bonus money, if promo codes need to be input, and which games are included in the bonus offer before making a deposit.
