How Are Online Slots for Real Money Similar to Land-Based Slot Games

If you look at the gameplay of slots, both online and land-based variations are quite similar. All you have to do is spin the reels and wait for the best possible outcome.

However, online real money slots have several important advantages compared to land-based ones, so let’s take a look at them.

  • You can play online slots wherever you are.
  • Real money slots have better progressive jackpot prizes.
  • There are thousands of available online slots, meaning the variety is much greater compared to land-based slots.
  • All kinds of innovative slots are released every month by leading providers.
  • The technology behind online slots is continuously upgraded to improve the overall player experience.

How Popular Are Online Real-Money Slots

Simply put, online slots are the most popular genre of casino games on the web. There are millions of players spinning the reels of their favorite titles every day. Slots are some of the biggest contributors to the revenue of many online operators.

No matter which online casino you decide to visit, you’ll notice that there are hundreds of slots available, as opposed to other casino games, which is an indicator of their popularity.

How to Play Slots for Real Money

Playing online slots is relatively easy. All you have to do is select your bet amount and click the Spin button. However, we decided to make a step-by-step guide on how to start playing online slots right away.

  1. Choose an online casino offered on this page.
  2. Open an account by filling out the sign-up form. Confirm your account.
  3. Make a deposit using one of the available payment methods.
  4. Claim the welcome bonus (most online casinos with slots offer welcome bonuses;
    we’ll talk about them later in the text).
  5. Select an online slot that you like the most.
  6. Place a bet and spin the reels.
  7. Hope for the best result!

Even if you want to play games other than slots, the process is quite similar. For example, if you’re going to play the best online roulette games, all you have to do is select an online casino that offers this type of game. The good news is — most of them do.

How to Play Real-Money Slots on a Mobile Device


There are two ways to play online slots on mobile. You can download a dedicated app or visit the casino via your mobile browser. The latter is the more popular option, as it works on all types of smartphones, whereas the operator has to develop two separate apps for Android and iOS devices. However, some mobile players still prefer using an app, even though not all online casinos offer apps.

We decided to give you a step-by-step guide on playing online real-money slots on mobile devices.

  1. Select a site from this list (try using the same one you already registered on).
  2. There are two options here.
    1. If you want to use an app, make sure to download it from the App Store or Google Play if available (alternatively, download the app from the website of the selected casino).
    2. If you want to play games in your mobile browser, just load the site.
  3. Open an account, log in and make a deposit (if you already haven’t).
  4. Select one of the available online slots.
  5. Enjoy playing slots on the go!

Mobile slots are popular because you can play them virtually anywhere. They are great for passing the time when you’re commuting or waiting in a line. However, you have to make sure that there’s always a stable Internet connection when you’re playing slots online for real money. Moreover, make sure not to run out of battery while spinning the reels, which can sometimes make your winnings void.


We already covered the overall process of joining an online casino. However, you should consider that some casinos also offer desktop apps that you can download, even though most players still prefer the instant-play option. What we’d like to discuss here is the difference between desktop and mobile slots.

The main advantage of playing slots on a PC is the bigger screen. If you tend to enjoy the design and animation quality in slots, this is the best option for you. On the other hand, mobile slots allow playing on the go, meaning you can access them anytime you like!

Moreover, PCs are plugged in and have more stable connections, which can sometimes be a disadvantage for mobile slot lovers who will not be able to play if they run out of battery or are in a remote area with a weak signal.

So, which one is better? It’s up to you to decide, as it’s a matter of personal preference.


The third option for playing mobile real money slots is to access them on your tablet. The process of signing up and playing games is pretty much identical to mobile devices. The only advantage is that tablets are bigger, enabling a more immersive experience when playing online slots.

To sum up, the three options you have for playing online real money slots are desktop, mobile, and tablet. All the best online casinos are available on each device, so choose the one that suits you most.

Online Slots With the Highest Payouts

Payouts from slots come in two forms: regular payouts from making combos and payouts from jackpots.

The payout usually refers to the amount of money that players, on average, earn compared to the amount of money wagered. This is also called RTP.

The average payout for online slots is somewhere between 90% and 97%. We’ll explain how these work in one of the following sections, where we’ll cover the concept of RTP.

Jackpot payouts are usually triggered randomly, meaning it’s difficult to determine the actual payout percentages. The only rule is that the higher the jackpot is, the more difficult it is to win one.

How to Pick a Casino for Playing Real Money Slots

Please pay attention to the following features when selecting an online casino.


Check out the other players’ opinions about the casino you want to join. Read reviews written by casino and slot experts. Several reviews are available on our site.

Licenses and Fairness

Make sure that an official regulatory body licenses the casino in question. Check whether it has fairness certificates to prove that it’s trustworthy.

Safety and Security

Does the casino in question have the latest safety and security protocols to protect you and your money from cyberattacks? Does it feature SSL encryption?


Visit the site’s Promotions section and check out the available bonuses for new and regular players. Read the underlying rules and T&Cs to learn more about wagering requirements, expiry dates, maximum cashouts, and more.

Banking Options & Payout Speed

The best casinos out there have plenty of banking options that can help you load the money to your casino balance and play real money slots games right away. Pay attention to available payment options, deposit & withdrawal speed, and transaction limits.

Mobile & Tablet Casino

Best Real-Money Slots for USA Players

Like it or not, some slots are available only in certain countries. In other words, as a casino enthusiast from the US, you can only access the games that are available in US casinos. This is actually not as bad as it might sound, given that the US is one of the biggest markets, meaning game providers frequently make new games for Americans.

Since there are hundreds of slots available, it’s difficult for us to pick just a couple of them. Slots are like art — you either like them or don’t. Therefore, instead of giving you the exact titles, we’ll provide three casinos which we believe to offer the best US slots.

Types of Bonuses for Real-Money Online Slots

Bonuses in online casinos can be divided into two primary categories: welcome bonuses and regular players’ promotions.

Welcome bonuses are offered to newcomers, and they can be claimed only once. Some casinos offer a no deposit welcome bonus, meaning that players don’t have to make a deposit to receive a reward. All they have to do is open an account. However, no deposit bonuses are usually much smaller compared to those requiring an initial deposit. These are called deposit match bonuses.

With a deposit match bonus, players who join and make a deposit will receive bonus money that usually “matches” the deposit. For example, if you deposit $100, you can receive $100 more in bonuses. Some welcome bonuses offer free spins as well.

Bonuses for regular players can be claimed once you use your welcome bonus (or if it expires). There are all kinds of promotions. Let’s explore them.

Free Spins Bonus

Some bonuses only offer free spins for online slots. You’re going to love them if your goal is to play real money slots.

Reload Bonus

Similar to match bonuses, except the amount you receive in bonus money is smaller. Match bonuses usually give you 100% (or more) on top of your deposit, whereas reload bonuses offer less than 100%. For example, if it’s a 50% bonus, you’ll receive $50 for every $100 you deposit.


Cashback is an exciting type of bonus that can make you feel better after a losing streak. When you activate this promotion, you’ll get some money back from the casino. For example, a 10% cashback money bonus will return $10 to your account if you lose $100 while playing online casino games.

Payment Method Bonus

Some casinos award players who use a specific banking option for making a deposit.

High-Roller Bonus

High rollers sometimes get special offers. These often require depositing a lot of money first (but receiving even more in bonuses).


Many online casinos have a VIP or Loyalty program where you can receive many additional bonuses and benefits.

Difference Between Casino Apps and Instant-Play Online Casinos

We already discussed that online casinos come in two forms – instant-play and casino apps.

Instant-play casinos are the most popular option nowadays as they offer the convenience of playing games as soon as you open an account, as opposed to “download” casinos where you need to take additional steps and install the software.

On the other hand, casinos that give players the option of installing a platform on their PCs or mobile devices often have more features. Keeping casinos in browsers means that operators cannot achieve the maximum possible customizability on their platforms. For example, mobile casino apps can offer push notifications to users, which isn’t possible with browser-based casinos.

What Is RTP and How Does It Affect Your Online Slots Experience?

We talked about payout in one of the previous headings and mentioned the concept of RTP. Payout and RTP are basically the same thing and refer to the amount of money returned to players when they spin the reels.

RTP stands for Return to Player, and this figure is usually displayed in percentages. For example, if the RTP is 95%, then $95 will be returned as prizes to lucky players for every $100 that players bet. In other words, casinos keep $5 as profit. However, slots are random, meaning some players might not win anything, while others can win huge prizes. Therefore, you can notice how RTP works only after observing payouts and bets over a more extended period.

Promotions and Bonuses for Real Money Online Slots

Many online casinos offer bonuses that are tailored to suit online slot players. Therefore, if you want to collect online slots for real-money bonuses, make sure to check some of the casinos featured on this page.

If the casino of your choice offers bonus money, read its T&Cs to learn whether you can use that money for slots wagering. In other words, some casinos can offer game-specific bonuses, so claiming a bonus for roulette to play online slots will not be possible.

On the other hand, if you collect a free spins bonus, it’s essential to know whether you can use it for all slots. This is usually not the case in online casinos, as they often offer game-specific free spins, meaning you can use the spins only in one specific title. Its name is indicated in the T&C of that bonus.

There are five things that you need to pay attention to when selecting a bonus.

  1. Wagering requirements
  2. Expiry date
  3. Minimum deposit
  4. Maximum cashout
  5. Game’s contribution to wagering requirements

Ideally, you should read the entire T&Cs for the bonus you want to claim to get familiar with all the rules. That way, you’ll be able to make the most of it and have an incredible online casino journey using bonus money (or free spins).

Choose the Best Online Casino With Real-Money Slots in Three Easy Steps

Playing Slot Games for Real Money – A Short Tutorial

If you haven’t had an opportunity to play slots before, don’t worry. Slots are the easiest of all casino games. There are literally two things that you need to do to play them.

  1. Place a Bet
    Select how much money you want to bet in your next spin.
  2. Click the Spin Button
    Wait for the reels to align and hope to make a combination out of the symbols on the reels.

All online slots nowadays offer the Autospin option, which lets you set the number of spins that you want to be executed automatically. That way, you can sit back and enjoy the show.

Many slots have unique features and symbols, so make sure to read more about them before playing the game. You wouldn’t be able to trigger these features manually — it all depends on your luck. Still, you should know how they work before you start playing the game.

Is It Safe to Play Online Slots for Real Money?

If the casino of your choice has a valid license, then it’s most likely safe. Online regulators won’t risk giving licenses to platforms that offer games by suspicious providers. All the best online casinos are regularly audited for fairness by independent companies. Therefore, you don’t have to worry about the games being rigged.

Still, being a little cautious when choosing a casino is always a good idea!
